Almost every clinician profile on ProVerdicts shows a ten-digit number labeled NPI. It looks bureaucratic, and it is — but it’s also the single most reliable way to make sure you’re looking at the right person.
What it is
The National Provider Identifier is a unique, ten-digit number assigned by the federal Centers for Medicare & Medicaid Services. Every health care provider who bills insurance electronically in the United States must have one — physicians, dentists, nurse practitioners, therapists, chiropractors, physical therapists and many more. Organizations such as clinics and hospitals have their own NPIs as well.
An NPI stays with a provider for life. It doesn’t change when they move to another state, join another practice or change their name.
What it’s good for
Telling people apart. There are many clinicians with the same name. If you’re trying to confirm that the Dr. Sarah Miller your friend recommended is the one at the address you found, the NPI settles it.
Looking someone up. The free federal NPI Registry shows each provider’s name, credential, specialty (called a “taxonomy”), practice address and, for many, a state license number.
Paperwork. Insurance forms, prior authorizations and referrals often ask for it.
What it isn’t
An NPI is not a license, a certification or a seal of approval. Getting one requires little more than an application; it says nothing about a provider’s quality or disciplinary history, and a provider whose license has lapsed may still have an active NPI. To check licensing, use the state’s verification tools — we explain how in how to check a doctor’s license in New York.
Why we show it
Every health profile on ProVerdicts is built around one NPI, which is how we make sure each page belongs to exactly one real person. Showing it lets you verify our information yourself — and if anything doesn’t match, tell us.
