How can we help?
Most of what people ask is below. For everything else, a human reads every email.
Getting started
Files, formats, and the first five free rows.
The National Provider Identifier is a 10-digit identifier used for covered health care providers in HIPAA standard transactions. Type 1 NPIs identify individuals, such as physicians or nurse practitioners; Type 2 NPIs identify organizations, such as group practices, clinics, and hospitals. Claims, referrals, and directories often key on it, which is why a wrong digit can be expensive.
A CSV with a header row. Beyond that, any combination of signals works: names, practice addresses, cities, states, ZIPs, phone numbers, specialties. The more corroborating signal a row carries, the higher the confidence the result can earn, but even a name and a state are enough to start an investigation.
No. Messy files are the expected input. The agent handles nicknames (Mike → Michael), misspellings, “Last, First” formats, credentials glued to names, marketing names, former names, and DBAs. It can also flag internal inconsistencies it finds, like a state column that disagrees with the ZIP.
Uploaded tables can hold up to 50,000 rows. Runs are orchestrated in parallel and streamed into the grid as rows finish, with app controls for how many rows process at once. Very large workflows should be split thoughtfully so you can review cost and results in manageable passes.
Yes. Set the NPI type filter when you map columns: Auto, Type 1 (individuals), or Type 2 (organizations). It's enforced inside the engine, so a row filtered to organizations can never come back with a person's NPI.
Results & accuracy
Confidence grades, no-matches, and how the gate works.
Every answer has to pass the name-identity gate: the chosen NPI's registered name must plausibly denote your entity, meaning the same person or the same organization. Address, ZIP, and phone corroborate a name match and set the confidence grade, but they can never substitute for one. A different practice in the same building is rejected no matter how perfectly the address lines up.
High — the registered name matches and a strong location signal (street or ZIP) corroborates it. Best candidate for normal downstream review.
Medium — the name matches but corroboration is weaker (city/state-level), or your file carried no address signal at all, which caps confidence at medium by design.
Low — a plausible match with thin corroboration. Treat these as your review queue; the per-row reasoning shows exactly what's missing.
It means the investigation found no NPI record that plausibly denotes your entity after checking registry and public evidence. You get the reasoning and the sources it checked. For directory hygiene, a well-explained no-match can be one of the most useful results in the file.
Not necessarily. Organizations hold many NPIs across locations, and individual providers move. A record whose name clearly denotes your entity is still a match at a different address; it just earns a lower confidence grade so you know to glance at it. The matched registry address is in the result, side by side with yours.
Discovery runs against the official CMS NPPES Registry first, then the open web for what the registry can't see (misspellings, marketing names, practice websites). Candidate NPIs are screened with the NPI check-digit algorithm and checked against NPPES during the run before they can receive high confidence. Any fallback that cannot be verified is capped low and flagged in the reasoning.
Open the row to see the full reasoning, every candidate NPI considered, and the source URLs. If something still looks off, rerun the row (a fresh $1 investigation), or send us the batch reference at support@npi-finder.com and we'll dig in.
Billing & credits
Costs, credit-backs, and the ledger.
$1.00 per completed row run, debited from a prepaid credit balance. New accounts start with $5.00 of free credit, enough for five row runs with no card required. There's no subscription and no minimum. Full details on the pricing page.
No. All credit purchases are final. Credits have no cash value, can't be transferred, and are never converted back to money. Once a row starts running, its credit is spent. They also never expire, so an unused balance simply waits for your next batch.
Automatically, whenever a row fails for reasons on our side: system errors, or runs you cancel before a row completes. The credit posts straight back to your balance with its own ledger entry as service credit. Completed research stays charged, including no-matches, because the investigation actually ran.
Add between $5 and $1,000 at a time through Stripe checkout, so card details never touch our servers. Top-ups of $100 or more earn a 10% credit bonus, added to your balance automatically. Credits post to your balance immediately, receipts arrive by email, and every movement is visible in your billing ledger inside the app.
No. Your balance carries forward until you spend it.
If you're resolving tens of thousands of rows or need invoiced billing, email support@npi-finder.com with your expected volume and we'll set something up.
Data & privacy
What you should upload, and what happens to it.
Provider business data: names, practice addresses, phone numbers, specialties. This is the kind of information that appears in public provider directories. Don't upload patient data or anything containing PHI; NPI Finder is built for healthcare entity resolution and provider identity, not patient records.
Your rows are processed by our resolution pipeline, which includes LLM and web-search providers, strictly to resolve them, and the results are stored in your account so you can return to your batches. Your data is never sold, shared for advertising, or used to market to the providers in your file.
Yes. Batches can be deleted from your home screen at any time. For a full account deletion, email support@npi-finder.com from your account address.
Sign-in uses verified email/password accounts with httpOnly session cookies, and payments run entirely through Stripe; we never see or store card numbers. Your credit balance and ledger live in our database keyed to your verified email.
