ASL Doctor Search — Source library
Public documentation snapshot: 2026-09-08
The official provider record - free, and in seconds.
Free bilingual search of the official U.S. provider registry, plus an in-browser DEA number check.
The official provider record - free, and in seconds.
Built for: A patient who got a referral and wants to know the practice is real and still at that address · A front-desk or scheduling person confirming a provider identifier before a claim goes out · Billing and credentialing staff sanity-checking an identifier against the authoritative federal record · A pharmacy or clinic worker who needs to catch a mistyped DEA number before it bounces something
ASL Doctor Search exists because of this.
You are usually trying to check one small thing. A referral came through and you want to know the office is real and still where the letter says. A claim bounced and you need the provider identifier that goes in the box. Someone handed you a number on a fax and one digit looks wrong. So you search the name, and the first screen you get is a row of lookup sites charging nineteen dollars to show you something the federal government publishes for nothing. The registry those sites are repackaging is free and public. But its own search wants exact spellings, speaks only English, and hands back a wall of codes rather than an answer. The deeper problem is what people think a result means. Someone finds an active record and decides the license must be current, the board certification real, the insurance accepted. It proves none of that. It means a person or an organization registered an identifier with the federal government, and that the registry holds whatever they last reported. An office that treats that as verification will eventually be wrong about something that matters, and nobody finds out until it costs them. And if DEA numbers cross your desk, you have the opposite frustration. A number that is simply transposed will kick back a prescription or a claim, and there is no quick free way to catch a bad check digit before it costs you an afternoon of phone calls. The tools that promise to check it want an account, and some of them want the number itself.
ASL Doctor Search exists because of this.
It asks the federal registry rather than serving a dataset it copied earlier - and it is specific about the one exception, a short-lived in-memory copy of a repeated identical query that is never written to disk.
ASL Doctor Search exists because of this.
The DEA check runs entirely on your device - the number never reaches us, is never stored, and never lands in a web address that could be shared or logged. The page even shows the arithmetic.
ASL Doctor Search exists because of this.
The honest limits are printed on the result itself. An active record is not a license check, and the page says so where you are looking, not in a terms link.
ASL Doctor Search exists because of this.
Free with no upsell path. The donation buttons are offered plainly, are disabled unless every payment link is valid, and provably do not gate, reorder, or alter results.
ASL Doctor Search exists because of this.
Spanish is a complete second experience, down to error text, the DEA calculation wording and the refund policy, rather than a translated front page.

No account, no ads, no paid placement, and no stored search history anywhere in the product.
ASL Doctor Search exists because of this.
One product across the website, an installable home-screen app, an Android app for invited testers, and a voice version in development - the same records and the same disclaimers on each.
How ASL Doctor Search works, start to finish.
ASL Doctor Search is a plain front door to the official U.S. provider registry. You type what you actually remember - a partial name, a clinic name, a specialty, a city, a state, a ZIP - and it asks the government registry directly rather than reading from a dataset it copied earlier. Results come back as readable cards rather than code tables: the name, the identifier, whether the record is active, the reported specialty, the practice address and phone number, and when the record was last updated. Every response is stamped with the time it was produced; because an identical repeat query can be answered for a few minutes from a short-lived copy held in memory, read that stamp as when you asked rather than as proof the registry was re-read at that instant. You can ask for ten, twenty or fifty results; fifty is the ceiling, and it is a ceiling, not a paywall step - there is no paid tier above it. Names are handled the way people remember them, not the way a database stores them. Partial names work as typed. The useful part is what happens when a search finds nothing: instead of shrugging, the tool retries. A combined entry like Chris Brad in the first-name box is re-run as a first and a last partial name, and a last name can be shortened by a letter, which is how Chris Brady surfaces - and the results line says plainly that you are now looking at partial-name matches. You can narrow to individual practitioners or to organizations, show only active records, sort by best match, name, most recently updated or nearest, and search within ten to two hundred fifty miles of a starting ZIP. Distance is honest about itself: it uses approximate ZIP geography and the addresses providers reported, it labels every figure as estimated, and it counts off the records it could not place rather than dropping them quietly. It also works best paired with a city or state, because it ranks and filters the batch of records your search already matched rather than sweeping the whole country by map. There are two identifier tools alongside the search. Type an exact ten-digit identifier and its own built-in check digit is verified on your device before anything is sent anywhere, so a typo comes back in an instant instead of as a confusing failure. The DEA tool checks a number for correct structure and checksum, and optionally compares the second letter against a registrant surname. That calculation never leaves your browser. The number and the name you type are not sent to us, not stored, not cached, and never placed in the page address, so they cannot end up in a shared link or a browser history that someone else reads. What the tool refuses to do is pretend. Every result states that an active record is not proof of a current license, board certification, accepted insurance, appointment availability, or clinical quality. A DEA check that passes says only that the number is shaped correctly and the arithmetic works - it says nothing about whether a registration is active, unexpired, or authorized for any particular schedule, and the page gives you the official registration tools and the DEA Registration Service Center number for that question instead of guessing. Where a provider reports a Colorado address, the result card itself links to the state's own license lookup. The guardrails sit on the result, not buried in a terms page nobody opens. Around that sit the practical bits. Save providers to your own device, where they stay - up to fifty of them, never uploaded, and they do not create an account. Export what you are looking at to a spreadsheet file. Copy a link to the search to hand to a colleague. Read the whole thing in English or Spanish, both complete rather than one being a translated afterthought, each at its own address. Add it to a phone or desktop home screen and it opens like an app, with the shell kept on your device but provider records and search responses deliberately never stored there. An Android app is out to invited testers, and a voice version is built but not yet published. Nothing anywhere asks for an account, shows an ad, sells placement, or keeps a record of what you searched. It is free, and the optional donation button provably changes nothing about what you see.
Everything in the current release.
Each of these is built and working today. Nothing on this list is a roadmap item.
Straight to the official registry, not a resold copy
There is no provider dataset sitting on a shelf here going stale between refreshes, and nothing is scraped or resold. Each search is a pass-through to the government's national provider registry. To avoid asking the registry the identical question repeatedly, a repeated search may be answered from a short-lived working copy held in memory - about ten minutes for a search, up to twenty-four hours for a repeat lookup of one exact identifier - so the time stamped on a response is when that response was produced, not a promise the registry was re-read that second. Nothing is written to disk and nothing is tied to a person.
Names the way you remember them
You rarely have the exact legal spelling, so partial names work as typed. The useful part is the retry: when a search finds nothing, it does not stop there. A combined entry like Chris Brad in the first-name box is re-run as a first and a last partial name, and a last name can be shortened by a letter - which is how Chris Brady turns up - and the results line tells you plainly that you are looking at partial-name matches rather than an exact hit.
Narrow it down without a manual
Filter by organization or clinic name, specialty, city, state, and practice ZIP, and choose whether you want individual practitioners, organizations, or both. Ask for ten, twenty, or fifty results. You can tick a box to show only active records, and sort by best match, name A-Z, most recently updated, or nearest.
Search by distance from a ZIP
Give it a starting ZIP and a radius of ten, twenty-five, fifty, one hundred or two hundred fifty miles and it can rank the nearest practices first. It is upfront that this uses approximate ZIP geography and the addresses providers themselves reported - every figure is labelled estimated - and it tells you how many records could not be distance-matched instead of silently dropping them. Pair it with a city or state for best results: it sorts and filters the batch of records your search already matched rather than searching the whole country by map.
Exact identifier lookup that catches your typo first
Paste a ten-digit provider identifier and its own built-in check digit is verified on your device before any request leaves. A transposed digit comes back immediately with a clear message instead of a slow, vague error. Valid numbers go straight through to the registry for the real record.
A DEA number check that stays in your browser
Enter a DEA number, and optionally a registrant last name, and the format, check digit, and surname initial are checked entirely on your own device. The number and the name are never sent to us, never stored, never cached, and never added to the page address. It also prints the arithmetic - the odd-position digits, the doubled even-position digits, the total and the expected final digit - in whichever language you are reading, so you can see exactly what it did.
Every result says what it does not prove
The limitation is printed next to the answer, not hidden in a policy page. An active record is not proof of a current license, board certification, accepted insurance, appointment availability, or clinical quality. A passing DEA checksum is not proof that the number belongs to a particular person or that a registration is active, unexpired, or authorized for any schedule.
A direct route to the answers this tool cannot give
Instead of guessing, it points you at the official source for each question. A result whose practice address is in Colorado carries a link to the state's own professional license lookup on the card itself. The DEA section links the official Diversion Control registration tools and prints the DEA Registration Service Center number, 1-800-882-9539, for anyone who needs actual registration status.
Save, export, and share
Save providers you are working through and they stay in that browser on that device, up to fifty of them - they are never uploaded here and they do not create a search-history account, and the page says so above the list. Export the results currently on screen to a spreadsheet file in one click, or copy a link that reopens the same search for a colleague.
Complete in English and Spanish
Both languages are full experiences, not a translated homepage over an English tool. Form labels, help text, error messages, the DEA calculation wording, and the donation refund policy all exist in Spanish at their own address, with the page marked as Spanish so screen readers and browsers handle it correctly.
Install it like an app
On a phone or a desktop it can be added to the home screen and opened without a browser bar. It keeps the shell of the app on your device so it opens fast and shows useful guidance when you are offline, but provider searches and health checks are explicitly excluded from that offline store - records are never kept there.
An Android app with native screens, not a wrapped web page
The current Android app draws native forms and result cards and makes its own requests, rather than hiding a browser view behind an icon - the project's first Android release did wrap the website, and this one deliberately does not. It declares exactly one permission, internet access, and carries no ads and no analytics tracking. It ships English and Spanish and registers with the phone's per-app language picker. The one published cold-start measurement - 278 ms with a clean log on a physical Google Pixel 8, on 2026-08-03 - was taken on a development build of the earlier version of this app, not on the newest signed build, which has so far only been through an emulator acceptance run. The app is available to invited testers on Google Play rather than listed publicly, and that newer signed build is finished but not yet uploaded.
Voice version, in development
A voice version is built and configured to answer requests such as finding a provider by name, by specialty and city, or by exact identifier, speaking the first three matches and placing five on a card. Its model builds with zero errors and passes the store's own certification validation, but it has never been submitted or published, and no successful end-to-end voice test has been recorded yet - treat it as coming, not available. It is US English only, and it carries the same honesty about what a record proves.
Free, with nothing hidden behind the free
There is no account, no ad, no paid placement, and no record kept of what you searched. Donation buttons are offered because the tool costs something to run, but they are optional and they never change access, ordering, or results, and the page says so where you can see it. Donations are not represented as tax-deductible, and the buttons stay switched off entirely unless all four payment links are correctly configured.
Numbers we can stand behind.
Every figure below comes from the product's own release record or test suite, not from a marketing estimate.
Numbers we can stand behind.
Accessibility is treated as a defect class, not a checkbox: a text-contrast problem measured on the live page was found, fixed, and re-verified at 5.39:1, and the fix was chased until it actually reached installed copies rather than stopping at the server.
Numbers we can stand behind.
It sends you elsewhere on purpose - to the Colorado license lookup and to the DEA's own registration tools - rather than implying it can answer questions it cannot.
Surfaces and status.
Status as of 2026-09-02. Verified directly against the running service on 2026-09-02. The health endpoint returned HTTP 200 reporting release 1.4.0 at 2026-09-02T12:02:15Z. A provider search the same minute returned real records from the federal registry stamped 2026-09-02T12:02:21Z, and a distance search from ZIP 80202 resolved 41 of 50 practice addresses and reported the 9 it could not place, exactly as the page promises. The donation-options response returned all four configured amounts with their disclosures - optional, does not affect access or results, not represented as tax-deductible. The Spanish home page, the donation refund policy and its Spanish version all returned HTTP 200. The distance search, active-only filter, sorting, saved providers, spreadsheet export and shareable search links are all present in the deployed 1.4.0 source. The Android and voice surfaces are deliberately not covered by this Live label - see their own status lines.
Worth more together.
Products on this platform share one sign-in, one support queue, and one engineering standard. These pair naturally with ASL Doctor Search.
ASL Verifier
If your office also has to confirm that the person in front of you matches the ID they handed over, Verifier does a strict one-to-one comparison and nothing else - no face search, no gallery, no surveillance, and it refuses to return a pass it cannot support.
ASL Vault
For the logins and credentials an office has to keep somewhere: a sealed store where the systems that file secrets away are structurally unable to read them back, and every reveal is recorded.
Recent progress.
This product ships often. The most recent verified changes, newest first.
Recent progress.
2026-08-13 the operator removed the Windows desktop application from the project entirely, narrowing the product to website, Android and voice.
Recent progress.
2026-08-13 /14: a real accessibility defect was found by measuring contrast on the live page rather than reading the stylesheet - a label rendering at 1.26:1 against a light background - and fixed; a second problem was caught in the same pass when the fix did not reach installed home-screen copies until the asset version marker was bumped, and it was then re-verified live at 5.39:1 with no regression on the dark sections.
Recent progress.
2026-08-22 the Android client was rebuilt with native screens and passed a fresh-install, launcher, foreground and screenshot acceptance run on an emulator; the physical-device rerun is still outstanding.
Recent progress.
2026-08-25 that build was signed and verified on the artifacts themselves - version 2.1.0, signature schemes confirmed, only the internet permission declared, and the signing certificate matching the one the store already has on file. Uploading it remains the current open step. As of.
Recent progress.
2026-09-02 the website is live on release 1.4.0, returning real registry records and resolving distance searches, re-confirmed by direct check that day.
Recent progress.
Free. Searching, both languages, and every surface cost nothing. Optional one-time donations of $5, $10, $20 or $50 are offered through Stripe's own hosted checkout - all four amounts confirmed live on 2026-09-02; the application never receives card numbers, donations are not represented as tax-deductible, and giving never changes access, ordering, or results. The donation buttons stay disabled unless all four payment links are configured and valid. A published refund policy covers duplicate, incorrect-amount or unauthorized donations reported within 14 days of the charge, reviewed case by case.
What does it cost, and what is the catch?
Searching is free and always has been - no account, no ad, no paid placement, no trial that expires. There are donation buttons for $5, $10, $20 or $50 because the tool costs something to keep running, and the page states plainly that donating never changes access, ordering, or results. Nothing is unlocked by paying, so there is nothing to catch you out later.
We already look this up on the federal registry site. Why use yours?
Because the federal search wants precision you often do not have, and gives you back codes rather than answers. This searches the same records, accepts partial names, and when a search comes back empty it retries rather than reporting nothing - re-running a combined entry like Chris Brad as a first and last partial name, and telling you on the results line that you are seeing partial-name matches. It also filters by specialty and location, sorts by distance from a ZIP, and reads the same in Spanish. You can save what you found, export a spreadsheet, and send a colleague a link to the search.
Is there anything to set up, install, or migrate?
No. There is no account to create, no data to import, and nothing to connect. Open the site and search. If you want it to behave like an app you can add it to a phone or desktop home screen, and there is an Android app out to invited testers, but neither is required and neither changes what you can search.
Can I use this to verify that a doctor's license or DEA registration is valid?
No, and the tool says so on every result rather than letting you assume otherwise. An active federal record means an identifier is registered, not that a license is current, a board certification is real, or insurance is accepted. A passing DEA check means the number is shaped correctly and the math works. For actual status, a Colorado result links to the state license lookup, and the DEA section gives you the official registration tools and the DEA Registration Service Center number.
What happens to what I search? Do you keep it?
There is no account and no stored search history, so there is nothing to attach a history to. Provider searches go to the federal registry and the results are shown to you rather than filed against your name; an identical repeat query may be answered for a few minutes from a working copy held only in memory, never written to disk and never tied to a person. DEA numbers are the strictest case: that check runs entirely in your browser, so the number and any surname you type are never sent, stored, cached, or added to the page address. Providers you save stay in your own browser and are never uploaded.
If I donate once and then stop, do I lose anything?
Nothing at all, because donating never bought you anything in the first place. Access, result order, and result content are identical for someone who has given fifty dollars and someone who has given nothing. If a donation was a duplicate, the wrong amount, or unauthorized, there is a published refund policy and a 14-day window from the charge to ask for a review.
Is it actually ready, or will it change under us?
The website is live today on release 1.4.0 - confirmed serving and returning real registry records on 2026-09-02 - with automated checks run against the built release before it is allowed to go live and each release traceable to the exact source it was built from. The Android app is out to invited testers with a newer signed build waiting to be uploaded, and the voice version has never been submitted to a store. Those two are named as not-yet-public rather than dressed up as finished.
How current is the data? How often do you refresh it?
There is no refresh cycle, because there is no dataset here to refresh - each search asks the federal registry. Two nuances worth knowing. Repeating the identical search inside about ten minutes, or the identical exact-identifier lookup inside twenty-four hours, can be answered from a short-lived working copy held in memory, so the time printed on a response is when that response was produced rather than a guarantee the registry was re-read at that instant. And the bigger limit is the registry itself, which holds what providers reported - so call the practice before you rely on an address or phone number.
Is this a government site? Are you affiliated with CMS or the DEA?
No. This is an independent search interface over publicly available federal data, run by Auto Secure Login. It is not operated by, affiliated with, or endorsed by any government agency, it does not provide medical advice, and it does not credential providers - the site's own footer states the last two. Where an official source is the right answer, it links you straight to that source.
Can our whole office use it at once, and is there a limit?
Yes, a team can use it without licenses or seats, because there is nothing to sign into. There is fair-use rate limiting - roughly 120 requests per ten minutes from one network address - so a runaway script cannot degrade the service for everyone. Ordinary searching by a front desk or billing team sits inside that, but it is shared across everyone on the same office connection, so sustained automated lookups from one office would hit it.
What should I know before I rely on it?
We would rather you hear this from us than discover it later. As of 2026-09-02:
What should I know before I rely on it?
This is a search interface over public records, not a verification service. An active record is not proof of a current license, board certification, accepted insurance, appointment availability, or clinical quality.
What should I know before I rely on it?
The DEA tool checks structure and the check digit only. A pass does not prove the number belongs to a particular practitioner, or that a registration is active, unexpired, or authorized for any schedule. Integrating live registration status was considered and deliberately ruled out on 2026-07-31, so this will not change quietly.
What should I know before I rely on it?
Data quality is whatever providers reported to the federal registry. Addresses and phone numbers can be out of date, and the tool tells you to call the practice to confirm insurance, new-patient status, services, accessibility, and the current address.
What should I know before I rely on it?
To avoid asking the registry the same question repeatedly, an identical repeated query can be answered from a short-lived working copy held only in memory - about ten minutes for a search, and up to twenty-four hours for a repeat lookup of one exact identifier. ZIP-level geography used for distance is held longer still, up to thirty days, because it barely changes. Nothing is written to disk and nothing is tied to a person, but a record changed at the registry inside that window may not show immediately on a repeated identical query, and the retrieval time printed on a response is when that response was produced rather than proof the registry was re-read at that moment.
What should I know before I rely on it?
Distance search is approximate, and it is a filter rather than a map search. It sorts and filters the batch of records your search already matched - not every provider near that ZIP - so a broad name with no city or state can return nothing nearby even when nearby providers exist. Add a city or state and it behaves as you would expect. Every figure is labelled estimated, and records that cannot be placed are counted off for you rather than dropped silently.
What should I know before I rely on it?
The state license link on a result covers Colorado only. For other states you would go to that state's own board.
What should I know before I rely on it?
Records are U.S. federal provider records. There is no international coverage.
What should I know before I rely on it?
The website and the Android app are English and Spanish. The voice version is US English only. No other languages yet.
What should I know before I rely on it?
Saved providers live only in the browser you saved them in, and the list holds up to fifty. Clearing your browser data loses them, and they do not follow you to another device - which is the deliberate trade for never uploading them.
What should I know before I rely on it?
The Android app is available to invited testers rather than as a public store listing. The newer signed build is finished but not uploaded, and it has not had a physical-device acceptance run under its own version - only an emulator run. The one published cold-start figure was measured on a development build of the earlier version.
The official provider record - free, and in seconds.
