Questions

How do I look up an NPI number in Massachusetts?

Type the provider's name in the search box on this page. The state is already set to Massachusetts, so you only see providers whose practice location is in MA. If you already have the NPI, type the 10 digits instead.

Does Massachusetts have its own NPI registry?

No. NPIs are federal, so every Massachusetts provider is in the national NPPES registry run by CMS. Massachusetts licensing boards keep their own license databases, and the NPI record lists the state license number the provider reported.

Is a Massachusetts license the same as an NPI?

No. The NPI is a 10-digit national number that never changes. A state license is issued by a Massachusetts board and can expire or be renewed. Provider pages here show both, but always confirm a license with the board that issued it.
