Medical Licensure and Board Certification Are Separate Credentials
A medical license is a state-issued authorization to practice medicine under that state's law. Board certification is a separate specialty credential awarded by a certifying organization after a physician meets that organization's education, training, assessment, and continuing-certification requirements.
Board certification does not replace a current medical license, and a state license does not automatically mean a physician is board certified.

What Is a Licensed Physician?
A licensed physician has received legal authorization from a state licensing authority. The Federation of State Medical Boards explains that state boards issue licenses for the general practice of medicine and regulate physicians under state medical practice laws.
Licensure requirements vary by jurisdiction and license type. They commonly address medical education, postgraduate training, examinations, identity, professional history, and other state requirements. Physicians must also renew periodically to maintain an active status.
A public license profile may show:
- The physician's recorded name
- License number and type
- Current status
- Issue and expiration dates
- Restrictions or conditions
- Final public board actions
It may not show a complete specialty, training, employment, malpractice, or hospital-privilege history.
What Is a Board-Certified Physician?
A board-certified physician has met the requirements of a named specialty certifying organization. Requirements depend on the certifying board and may include accredited specialty training, examinations, professionalism standards, and ongoing activities.
In the United States, two widely recognized certification systems include:
- The American Board of Medical Specialties (ABMS) and its member boards
- The American Osteopathic Association (AOA) specialty certifying boards
Other organizations may also use the phrase board certified. Always identify the exact certifying body, specialty, certification status, and verification source rather than relying on the phrase alone.
Does Board Certification Mean a Doctor Is Better?
Board certification documents that a physician met a certifying body's requirements in a specialty. It should not be turned into a guarantee of a diagnosis, treatment result, recovery time, complication rate, safety, or patient experience.
When choosing a physician, certification can be one relevant factor alongside:
- A current and appropriate state license
- Experience with the condition or procedure
- Hospital or clinic affiliation
- Insurance participation and access
- Communication and accessibility
- Recommendations from a treating professional
- Your individual medical needs
A physician may have extensive relevant experience even when certification is not current or was never pursued. If certification matters for a particular treatment, ask the physician or clinic about the credential and verify it with the certifying organization.
How to Verify a Medical License
- Search the physician's name or license number on DoctorLicenseLookup.com.
- Match the correct person using the state, number, and license type.
- Review the status, expiration date, and public conditions.
- Confirm important information with the issuing board through the official medical boards directory.
You can also begin with a state page such as the California medical license lookup or Idaho medical license lookup.

How to Verify Board Certification
ABMS certification
Use the ABMS Verify Certification page, which directs patients to its Certification Matters lookup. Match the physician carefully and review the specialty and current certification information shown.
AOA certification
Use the AOA Board Certification resources or the applicable AOA specialty certifying board. If online verification is unclear, contact the organization directly.
Any other certification claim
Ask these questions:
- What is the full name of the certifying board?
- What specialty or subspecialty is certified?
- Is the certification current?
- Is there an official verification page?
- Does the certifying body explain its training and assessment standards?
Do not assume that a state medical board profile contains complete or current board-certification information. Verify licensure and certification separately.

MD, DO, License Type, and Specialty
MD and DO are medical degrees. State boards may issue licenses to allopathic physicians (MDs) and osteopathic physicians (DOs), sometimes through separate boards.
A license type is also not necessarily a specialty. A full physician license may authorize the general practice of medicine under state law, while specialty certification describes a separate field of certification. For this reason, a license profile's “profession” or “type” field should not automatically be read as proof of specialty certification.
Can a Licensed Doctor Practice Without Board Certification?
State licensure provides the legal authorization defined by that state. Board certification is a separate credential and is not universally required for every physician or practice situation. However, hospitals, employers, insurers, or clinical programs may establish their own credentialing requirements.
For a specific service, ask the relevant hospital, clinic, insurer, or physician what credentials are required. DoctorLicenseLookup is not a credentialing service and should not be used for employment or another FCRA-governed decision.
Can Board Certification Expire?
Certification status and continuing requirements depend on the certifying organization and certificate. Some certificates are time-limited, and organizations may require ongoing activities to maintain certification.
Check the current status at the certifying body's official source. Do not rely on an old biography, advertisement, or screenshot.
Common Verification Mistakes
- Treating licensed and board certified as synonyms
- Assuming an active license proves a specialty
- Using an NPI as proof of licensure or certification
- Checking only the physician's practice state when several licenses may exist
- Accepting “board certified” without identifying the certifying body
- Treating certification as a guarantee of a particular outcome
- Relying on a third-party profile without confirming the official sources
