What is an NPI Number?

A National Provider Identifier is a unique 10-digit ID issued by CMS to every US healthcare provider for HIPAA-compliant billing and transactions.

NPI-1 vs NPI-2

NPI Type 1 identifies individual practitioners (doctors, nurses). NPI Type 2 identifies organizations, hospitals, and clinics.

Wildcard Search

Use * in name fields — e.g. John* matches Johnson, Johnston, and more.
