National Provider Identifier (NPI) Registry Lookup and Verification Tool
Free NPI lookup: search the official CMS NPPES NPI Registry by provider name, 10-digit NPI number, specialty or organization to find any doctor's or clinician's National Provider Identifier. Then verify the provider in one place: state licenses, OIG exclusion status, Medicare enrollment, industry payments and published research.
Look up
A name (Jane Smith), a last name and state, an organization, or a 10-digit NPI.
Check
Registry status, OIG and Medicare checks, licenses, industry payments and published research.
Download
Excel or PDF for any provider, free. With 2MM+, download whole selections and verify lists of NPIs at once.
Public records from CMS, HHS-OIG, GSA, the National Library of Medicine and ClinicalTrials.gov, shown as published, with the date each was checked. Confirm licenses and discipline with the state board. This tool is not a consumer report and must not be used as one.
How to look up an NPI number
Type a provider’s name, an organization’s name or a 10-digit NPI in the search box, and add a state to narrow common names. Every result opens the provider’s full record from the CMS National Plan and Provider Enumeration System (NPPES), the official source of NPI numbers, read live when you search.
- By name: a first and last name (Jane Smith), or a last name with a state.
- By NPI number: all 10 digits. The check digit is tested first, so a mistyped number is caught before the search.
- By organization: a hospital, clinic, group practice, pharmacy or laboratory name, with Organizations selected.
What an NPI record shows
- Registry details: practice location, phone and fax, NPI type, enumeration date, last update, other names and other practice locations.
- Specialties and licenses: every taxonomy code with its state license number, and a link to confirm the license with the state board.
- Exclusions and Medicare: the HHS-OIG exclusion list (LEIE), CMS deactivated NPIs, Medicare enrollment, ordering and referring eligibility, and Medicare opt-out.
- Industry payments: yearly totals from CMS Open Payments.
- Research: PubMed papers found with a standard author search on the clinician’s name, and ClinicalTrials.gov studies that list them as an official in their state.
Type 1 and Type 2 NPIs
A Type 1 NPI belongs to an individual clinician, such as a physician, nurse practitioner, physician assistant, pharmacist or therapist. A Type 2 NPI belongs to an organization, such as a hospital, group practice, nursing home, pharmacy or laboratory. A clinician keeps the same NPI for life, even after moving or changing jobs.
Verify a list of NPIs
Practices, billing teams and researchers can check a whole list at once with 2MM+: paste NPIs or upload a CSV or Excel file to see which numbers are valid, active and clear of the OIG exclusion list, then download the results. Members can also watch providers and get an email when a record changes.
NPI lookup questions
What is an NPI number?
A National Provider Identifier is the 10-digit number CMS assigns to every US health care provider and organization that bills electronically. It stays with the provider for life, across jobs and states.
How do I find a provider's NPI number?
Search by the provider's name, add a state for common names, and open the matching record. The NPI is at the top of the record with a copy button.
Is NPI information public?
Yes. CMS publishes the NPI registry (NPPES) as public information, including names, practice addresses, phone numbers, specialties and license numbers.
Is this NPI lookup free?
Yes. Searching, opening records and downloading one provider's record are free, with no account. 2MM+ members can also verify whole lists, download many providers in one file and keep a watchlist.
Why can't I find a provider?
Check the spelling, try the last name only, or remove the state. Deactivated NPIs drop out of the live registry; enter the number to check whether it was deactivated.
Can I check malpractice history here?
There is no national public malpractice database. Each state board keeps license and discipline records, and some (Massachusetts, for example) list paid malpractice claims. The Licenses tab links to the board for each license.
How current is the data?
Searches read the CMS registry live. Exclusion lists, Medicare files and industry payments are checked against the latest files CMS, HHS-OIG and GSA publish; each check shows its date.
