How to Verify a Doctor's License: A 5-Minute Check Anyone Can Do

Every licensed physician in the United States appears in a public record that anyone can check for free in about five minutes. You need only their name and state: the state medical board's lookup shows whether the license is active, when it expires, and whether the board has ever taken disciplinary action. Here is exactly how to do it, and what each source can and cannot tell you.

Why bother checking

Most people never verify a doctor's license, and most of the time nothing bad comes of that. But the check matters most precisely where care feels least familiar: a new provider, an online visit, a clinic you found through an ad. Licensing is the floor of legitimacy in American medicine, and it is the one credential that is fully public, free to check, and maintained by a government body rather than the provider themselves.

Step 1: The state medical board

Each state's medical board licenses physicians and runs a public lookup, almost always on a .gov domain. Search for your state's name plus "medical board license lookup", or start from the board list maintained by the Federation of State Medical Boards. A typical record shows:

• full name and license number,
• license status (active, expired, suspended, surrendered),
• issue and expiration dates,
• the medical school and year of graduation in many states,
• formal disciplinary actions, if any.

If the name search returns nothing, check the spelling and try the physician's legal name; if it still returns nothing for the state where they claim to practice, that is a serious red flag.

Step 2: DocInfo, the cross-state view

Physicians are often licensed in several states, which matters for telehealth. DocInfo.org, a free service of the Federation of State Medical Boards, aggregates licensing and disciplinary data nationwide: one search shows every state where a physician holds or has held a license and any board actions on record. It is the fastest single check when you do not know which state to start with.

Step 3: The NPI registry, and what it is not

Every US provider has an NPI, a 10-digit National Provider Identifier used for billing and e-prescribing. The public NPI registry is useful for confirming identity: name, specialty, and practice details.

One honest caution, because this is the most common mistake in provider verification: an NPI is an identifier, not a credential. Having an NPI does not mean a provider is licensed, in good standing, or even currently practicing. Sites that present an NPI as proof of legitimacy are overselling it. License status lives with the state board, full stop.

How to read a disciplinary record

Finding a board action on a record is not automatically disqualifying, and reading it well takes thirty seconds:

• What was it for? A paperwork violation, a continuing-education lapse, and a patient-harm finding are very different things.
• When was it? A citation from 1998 with a clean record since tells a different story than an action last year.
• What was the outcome? A reprimand, a fine, a practice restriction, and a revocation sit on very different points of the severity scale.

If anything in a record concerns you, you can ask the provider about it directly. Legitimate professionals answer credential questions without defensiveness.

The telehealth wrinkle

In US telehealth the general rule is simple: the physician must be licensed in the state where the patient is located during the visit. That means the license you check is the one for YOUR state, not the state where the platform is headquartered.

Two things a legitimate telehealth service should always be able to tell you: the name of the physician who reviewed your case, and the state license under which they did so. With those two facts, the verification above works exactly as it does for an in-person doctor. For the pharmacy side of the same check, see our guides to what LegitScript certification verifies and how 503A compounding pharmacies are regulated. Majesta publishes its own physician roster with names and states so this check takes minutes, and how Majesta works describes who reviews each case.

Questions worth asking any provider

• Which state license will my prescribing physician be practicing under for my visit?
• Where can I see the name of the physician who reviewed my case?
• Is your specialty certification current, and with which certifying board?
• Who do I contact if I want my records or have a concern about my care?

The bottom line

License verification is one of the few consumer protections in healthcare that is free, public, and takes minutes: state medical board first, DocInfo for the cross-state view, the NPI registry for identity but never as proof of licensure. Do the check whenever a provider is new to you, and treat any provider you cannot verify, or any platform that will not name your physician, as a provider you do not use.
