How to verify a healthcare provider's credentials before your first visit

Most people pick a doctor based on a referral, a name their insurance app spits out, or whoever has an opening next week. That's a perfectly reasonable starting point. But before you hand your medical history to a stranger, it's worth a few minutes confirming they are who they claim to be — and that their license is in good standing.

Start with the NPI

Every legitimate U.S. provider has a National Provider Identifier: a unique 10-digit number issued by the federal government. It never changes, and it's public. If a provider has an NPI, they're enumerated in the official CMS registry — the same data Carenary is built on. You can pull up any record on the official NPI Registry, which shows the provider's name, primary practice address, and listed specialty.

An NPI tells you the provider exists in the federal system and what type of provider they are. It does not, on its own, tell you whether their state license is active. That's the next step.

Check the state license

Doctors, dentists, nurses, and most other clinicians are licensed by the state where they practice, not by the federal government. Every state has a board with a free public lookup — search "[your state] medical board license lookup." There you can usually see the license number, its status (active, expired, suspended), when it was issued, and any public disciplinary actions.

If a license shows anything other than active, slow down and ask questions. A disciplinary note doesn't always mean you should walk away, but you deserve to know about it before you book.

Treat board certification as a plus, not a requirement

Board certification means a physician passed extra exams in their specialty through a body like the American Board of Medical Specialties. It's a real mark of expertise, and you can confirm it at certificationmatters.org. That said, plenty of excellent, fully licensed doctors aren't board-certified in every area they practice, so weigh it as a bonus rather than a dealbreaker.

A quick gut check

• Do the name and specialty on the NPI record match what the office told you?
• Is the practice address real and reasonably close to where you'll actually be seen?
• Is the state license active, with no surprises?
• If the stakes are high — surgery, psychiatry, oncology — is there board certification to back it up?

None of this requires phone calls or a paid service. The records are public. The point of a directory like Carenary is to hand you the verified starting point — the NPI, specialty, and location — so the rest takes minutes, not an afternoon.
