How to find my doctor’s NPI number

Health Portability and Accountability Insurance (HIPAA), which became law in 1996, continues to have widespread effects in the US healthcare industry. HIPAA Administrative Simplification Rules established a National Provider Identifier, or NPI, and began using the numbers, on May 23, 2007 Both providers and individual organizations use their NPI in administrative and financial transactions. The Centers for Health and Human Services Department for Medicare & Medicaid Services maintains a registry of NPI searches that is publicly available.


1. Open the “National Plan and System Provider Enumeration” search page at

2. Click the “Find the NPI Registry” link. This will open the “NPI Registry Search Start” page. Both individual providers and organizations and medical practices can have non-pharmaceutical interventions. Click on the “Individual Provider” or “Organizational Provider” link to open the “NPI Record Search” page.

3. Fill in at least one field in the search engine. Note that if you select the status field, you must fill in another field as well. If you are unsure of the spelling of a search term, you can use a wildcard search. To enter a wildcard search, fill in at least two characters of the search term, followed by an asterisk (*). For example, filling in the “Provider Last Name” field with “Sm **” will find providers whose last name begins with “Sm”, such as “Smith” or “Smythe”.

4. Click on “Search”. The page will display the search results. Click on the NPI number for any result that appears to see more information about that provider.

Tips and Warnings

  • The more fields you specify in the search box, the narrower your search will be. If you are having trouble finding a provider, try searching with fewer criteria or using a wildcard to explain spelling differences.
  • People who join can be listed as organizations on the NPI Registry.
