A National Provider Identifier (NPI) is the 10-digit federal ID number every billing provider, physician, and healthcare organization is assigned by CMS. This tool searches the free public NPPES NPI Registry directly from your browser, by NPI number, provider or organization name, state, or specialty — useful for verifying a rendering provider before you bill, confirming an organization's group NPI, or double-checking a taxonomy code on file.

Fill in as few or as many fields as you like — an NPI number alone is enough for a direct lookup.
If you enter an NPI number, all other fields below are ignored.
