Doctor license lookup: how to check a license and disciplinary history in every state
Every state publishes physician licenses and disciplinary actions. Most people never look. Here is exactly how, what the results mean, and which red flags matter.
Where to look
- Your state medical board. Search "[state] medical board license lookup". Every state has one, and they are free. Osteopathic physicians are sometimes on a separate board.
- DocInfo.org. The Federation of State Medical Boards aggregates licensing and discipline across states. Useful when a doctor has practiced in several.
- The National Practitioner Data Bank public file. Aggregated, de-identified data on malpractice payments and adverse actions. It will not name your doctor, but it shows how common actions are.
- The OIG exclusion list. Clinicians barred from Medicare and Medicaid, usually for fraud or patient harm.
How to read the result
Look for four things:
- Status: active, expired, inactive, suspended, revoked, or surrendered. Only active means they can practice.
- Restrictions: probation, practice limits, supervision requirements.
- Board actions: consent orders, reprimands, fines. Click through; the document usually says why.
- Other states: a doctor who surrendered a license in one state and moved to another will show clean in the second unless you check the first. DocInfo helps here.
What counts as a red flag
- Any revocation, suspension, or surrender, in any state, ever. Licenses are rarely lost for small things.
- Consent orders involving prescribing, sexual misconduct, substance use, or fraud.
- A pattern: two or more actions over a career.
- Discipline in one state followed by a fresh license in another.
A single old reprimand for record-keeping is worth a question, not a disqualification.
Finding a doctor's license number or NPI
The license lookup itself returns the license number. The NPI, a separate 10-digit federal identifier every clinician has, is public at the NPPES NPI Registry. The NPI is what DoctorDirectory.ai verifies live when a clinician applies: the name on the application has to match the registry, the record has to be active, and the taxonomy has to be one we list.
What we check so you do not have to
Every listed clinician's license is verified against the national registry when they apply, and their public record is screened for board actions, news of ethical violations, criminal cases, and anti-evidence content before a person reviews the file. Anyone who has ever lost, surrendered, or had a license restricted for cause is not listed, full stop.
Common questions
Do doctors have to be licensed in each state?
Yes, to see patients located in that state, including by telemedicine. The Interstate Medical Licensure Compact speeds up getting additional licenses but does not remove the requirement.
How often do doctors renew a license?
Every one to three years depending on the state, with continuing education requirements.
Can I see malpractice lawsuits?
Sometimes. Some state boards publish malpractice payments above a threshold. Court records are public but scattered. A lawsuit alone is weak evidence; many good doctors are sued, and many bad ones are not.

Why this matters
You now know how to check a doctor yourself. We built a directory that does every one of those checks before a name appears.
DoctorDirectory.ai is different on purpose. Every clinician is verified against the federal license registry, screened across their website, social accounts, board actions, and news, and signs a dated attestation to the major society guidelines that renews every year. Websites are re-checked monthly and listings are audited at random. Nothing a clinician or advertiser pays for changes who passes or who ranks. And there are no patient reviews to buy, bulk-post, or weaponize. That is what a vetted directory looks like, and it is what a healthcare system running low on trust needs more of.
For patients
Find the right doctor, then tell someone.
Search by condition and city. Every result is licensed, board-certified, and on record for evidence-based care. If a friend or family member is choosing a doctor, send them here before they read a single star rating. The more people who expect this standard, the more clinicians will meet it.
For clinicians and the medical community
Vetting and guardrails are how we earn trust back.
A license proves training. It does not tell a patient who sells peptides, who tells families to skip vaccines, or who quietly lost a license in another state. Directories that verify, attest, re-check, and remove are the guardrails the profession has been missing. If you practice from the evidence, put your name to it where patients can see it, and ask your colleagues to do the same.
