How to find an NPI number
- Search by name or organization. Enter the provider’s name, organization, or a 10-digit NPI in the box above. For an individual, the lookup-by-name tool lets you type first and last name in separate fields.
- Match the right record. Compare the specialty, credentials, city, and state on each result to make sure you have the correct provider before opening the profile.
- Read and verify the NPI. Open the profile to see the 10-digit NPI number, taxonomy, and practice address. Confirm the record is active against the official CMS NPPES registry.

Frequently asked questions
What is an NPI number lookup?
An NPI lookup finds the National Provider Identifier — the unique 10-digit number CMS assigns to a U.S. healthcare provider or organization. Enter a name or NPI to retrieve the record.
How do I find a provider’s NPI number for free?
Search by name or organization above, or use the lookup-by-name tool. Every result links to a profile with the NPI, taxonomy, and practice location at no cost.
How do I verify that an NPI number is valid?
Use the NPI validator to check the 10-digit check digit, then look the number up here to confirm it is issued to a real provider in NPPES.
What if I can’t find the NPI I’m looking for?
Try the last name only, check the spelling, or remove the state filter. Newly issued NPIs appear once CMS publishes them in the monthly NPPES file.
