Checking an organization
- Match the NPI to the exact location you will visit or bill; each location can have its own.

Common questions
Why does Entro have 7 NPIs?
An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Entro's NPIs list practice locations in 2 cities.
Is an organization NPI a license?
No. An NPI identifies who bills. Facilities and the clinicians who work there are licensed separately by the state.
