NPI Number — Common Questions
What is an NPI number?
An NPI (National Provider Identifier) is a unique 10-digit identification number issued by CMS to every US healthcare provider. It is required on all standard healthcare transactions — claims, eligibility checks, referrals, and prior authorizations. The NPI is permanent and does not change if a provider moves or changes specialties.
What is NPI used for?
NPI numbers identify healthcare providers in billing, credentialing, and insurance transactions. Individual providers use a Type 1 NPI for prescribing and rendering services. Group practices and facilities use a Type 2 NPI for billing claims and network contracting.
How do I find my NPI number?
Search by your name and state in the box above, or log into the NPPES portal at nppes.cms.hhs.gov. You can also check your CMS approval letter or health plan credentialing correspondence.
Is the NPI lookup free?
Yes — this NPI lookup is completely free and requires no registration. Data is sourced from the NPPES NPI Registry, updated monthly by CMS.
What does PECOS enrolled mean?
PECOS (Provider Enrollment, Chain, and Ownership System) is the CMS Medicare enrollment system. A PECOS-enrolled provider is actively enrolled to bill Medicare. We display PECOS status on every provider profile.
What is the LEIE exclusion list?
The LEIE (List of Excluded Individuals and Entities) is maintained by the OIG. Providers on this list are excluded from Medicare and Medicaid programs. We flag excluded providers with a warning badge on their profiles.
How often is the NPI database updated?
The NPPES NPI Registry is updated monthly by CMS. Our database is refreshed within days of each CMS release. The exact update date is shown on every page.
