What you're searching

NPI registry, NPI finder, NPI number search. Same database, better answers.

An NPI (National Provider Identifier) is the 10-digit ID every U.S. healthcare provider and organization uses on claims, prescriptions, and referrals. This search runs on CMS's own NPPES registry data, the same source behind every NPI lookup tool.

Find an NPI by name

Type a last name ("smith"), last then first ("smith john"), or either order. Organizations match on their registered name. Add a state to cut a common name down to your territory. Typing a 10-digit number looks the NPI up directly.

Need an NPI prescriber lookup?

A registry tells you a prescriber exists. Profiles here add what a rep actually needs: Medicare billing volume, top procedure codes, Part D prescribing context, and disclosed industry relationships, where that public data exists. Look for the Billing profile button on results.

By state

NPI lookup by state

Every state has its own page with provider counts by city and specialty.

Where this data comes from. Provider identity, specialty, and practice location come from CMS's public NPPES registry (the National Plan & Provider Enumeration System), the official record of every NPI ever issued. Deactivated NPIs are excluded. Addresses are what the provider filed and can lag a move. Where a profile shows Medicare context, it comes from CMS's public utilization, Part D, and Open Payments files: traditional Medicare fee-for-service only, and CMS suppresses any provider-and-code line under 11 beneficiaries before publishing. An Open Payments record is a disclosed relationship, not evidence a clinician uses a product. Prospect 811 organizes public data; it doesn't add to or alter it. Not affiliated with or endorsed by CMS. Full detail on the data page.

Knowing the NPI is the easy part.

Prospect 811 turns the same public data into a ranked call list: who actually bills your codes, in your territory, with history and contact detail.
