Physicians who move across states, accept residency assignments, or practice telemedicine can face a simple but essential question: Do doctors need to be licensed in each state? As of April 2026, the American Medical Association (AMA) states that every state requires practicing physicians to obtain a medical license, and physicians often require a separate license for each state where they practice, including telemedicine.
This requirement can result in additional applications, fees, credential verification, and renewal duties for physicians practicing in several states. The Interstate Medical Licensure Compact (IMLC) can alleviate some of the administrative burden for eligible physicians. As of June 2026, 44 states, the District of Columbia, and Guam are part of the Compact, with over 200,000 licenses issued through the program.
Understanding state-specific physician licensing standards can help doctors and healthcare organizations avoid practice disruptions and credentialing issues.
Why Physician Licenses Are State-Based
In the United States, medical practice is regulated primarily at the state level. Each state and several U.S. jurisdictions have laws that define who may practice medicine and give medical boards authority to issue and oversee physician licenses.
State medical boards determine the qualifications physicians must meet before receiving a license. Requirements can cover medical education, postgraduate training, licensing examinations, professional history, and other documentation. FSMB maintains state-specific requirements because these standards can differ by jurisdiction.
This state-based system protects patients by requiring physicians to meet the legal and professional standards established in the jurisdiction where they practice. A physician’s MD or DO degree simply does not confer legal authority to practice medicine.
One License Usually Does Not Cover Every State
A physician generally needs a separate license for each state where the physician practices. The AMA’s April 2026 guidance confirms that current licensing processes generally require separate licenses for physicians practicing in multiple states, including telemedicine.
This can mean additional applications, fees, verification, renewals, and compliance tracking. The FSMB Uniform Application can reduce repeated data entry for physicians applying to participating boards, but it does not address state-specific requirements.
How Physician Licensing Requirements Vary by State
State medical boards regulate physicians’ licensure. Therefore, criteria vary significantly among jurisdictions. The FSMB maintains state-specific standards because physicians must conform the rules and regulations of the board from which they seek a license.
Common Requirements for Physician Licensure
Most state boards review a physician’s education, postgraduate training, licensing examination history, and professional credentials. FSMB reports that all state medical boards require candidates to complete either the USMLE or COMLEX-USA sequence, while postgraduate training requirements vary by jurisdiction.
Depending on the state, an application may require:
1. Medical school transcripts and diploma
2. Residency or postgraduate training verification
3. USMLE or COMLEX-USA results
4. Professional references
5. Background and identity information
6. Current and previous licenses
7. Primary-source credential verification
8. Additional state examinations or documentation
Why Medical License Requirements by State Differ
Each state operates under its own medical practice laws and gives its medical board authority to regulate physician practice. This allows jurisdictions to establish requirements based on their statutes, regulations, and public-protection standards.
That means a physician who qualifies in one state should not assume the same requirements apply elsewhere. Examination attempt limits, training requirements, time limits, credential verification, and state-specific examinations can vary.
MD and DO Licensing Considerations
Both MD and DO physicians must obtain state authorization to practice. FSMB notes that state boards issue licenses for general medical practice through allopathic, osteopathic, or combined regulatory structures.
Requirements can differ for MD and DO applicants in certain jurisdictions. FSMB’s current state data contains differing MD and osteopathic requirements in Arizona, California, Florida, Michigan, Oklahoma, Utah, Vermont, and Washington.
The most secure approach for physicians and credentialing teams is to check the current state board regulations before submitting an application. The FSMB also suggests confirming current information directly with the relevant board because regulations can change.
Can a Doctor Practice in Another State Without Getting a New License?
In most cases, a physician cannot simply use a home-state medical license to practice in another state. State law controls whether an additional license, endorsement, compact pathway, or limited exception applies.
What Happens When a Physician Moves to Another State?
A physician who relocates generally must apply for a medical license in the new state before practicing there. The application may require education and training records, examination history, credential verification, background information, and other state-specific documents.
A physician should also check whether the new state offers licensure by endorsement or participates in the IMLC. These options can reduce repeated application work for eligible physicians, but the new jurisdiction still issues its own license.
What If a Doctor Works in Two States?
Physicians who regularly provide care in two states generally need active authorization in both jurisdictions. This applies to in-person practice and may also apply to telemedicine based on the state’s rules and the patient’s location.
For practice managers and credentialing teams, each license should be tracked separately, including its number, status, expiration date, and verification record.
Does a Medical License Transfer Between States?
A medical license generally does not transfer automatically from one state to another. The AMA reports that few states provide traditional reciprocity, so physicians commonly need separate licenses for each state where they practice.
The FSMB Uniform Application can help physicians apply to multiple participating state boards by reusing core application information. It does not replace each state’s licensing authority or state-specific requirements.
What Are the Basic Steps to Get a Medical License in Another State?
Applying for another state medical license requires careful review of that jurisdiction’s current rules. Requirements, documents, fees, and processing procedures can vary, so physicians should confirm details with the applicable medical board.
1. Check the State Medical Board
Start with the official medical board for the state where you plan to practice. Review eligibility rules, application instructions, fees, examination requirements, and any state-specific conditions.
FSMB provides state-by-state licensing information, but it advises applicants to confirm current requirements directly with the relevant board.
2. Confirm Your Eligibility
Review whether you meet the state’s requirements for:
1. Medical education
2. Postgraduate training
3. USMLE or COMLEX-USA examinations
4. Existing medical licenses
5. Professional history
6. Background screening
Requirements can differ significantly among states.
3. Gather and Verify Documents
Common application materials may include:
1. Medical school transcripts
2. Diploma
3. Residency verification
4. Examination records
5. License verification
6. Identification documents
7. Professional references
Some boards may require primary-source verification or participation through the Federation Credentials Verification Service (FCVS).
4. Submit the Application and Fees
Complete the state application and provide all required supporting documents. Missing information or unresolved discrepancies can delay review.
5. Complete State-Specific Requirements
Some jurisdictions may impose additional examinations, training, background checks, or other requirements. Physicians should complete these requirements before assuming that they are qualified to practice.
6. Confirm the License Before Practicing
Once approved, verify the license status, effective date, and any restrictions. Practice managers and credentialing teams should also update provider records, payer files, and internal compliance systems.
What Is the Difference Between Medical Licensure and Board Certification?
Medical licensure and board certification are separate credentials with different purposes. A state medical license provides legal authority to practice medicine, while board certification demonstrates specialty-specific professional qualifications.
Medical Licensure
A state medical board can issue a medical license and provides a physician legal permission to practice medicine in that jurisdiction, subject to applicable rules and regulations.
Licensure requirements may include:
1. Medical education
2. Postgraduate training
3. Licensing examinations
4. Background checks
5. Credential verification
6. Professional history
A physician generally needs the appropriate state license before providing medical services in that jurisdiction.
Board Certification
Board certification is a voluntary specialty credential awarded by a recognized medical specialty board. It indicates that a physician has met the board’s requirements for education, training, examination, and continued professional development.
Board certification may support:
1. Hospital credentialing
2. Payer credentialing
3. Professional recognition
4. Specialty-specific practice requirements
Why the Difference Matters for Credentialing
Credentialing teams should record licensure and board certification separately. A physician may be board-certified but still need an active license in the state where care is provided.
For medical billing and compliance teams, verifying the correct state license is especially important because professional credentials, payer enrollment, and billing authorization are separate requirements.
Common Physician Licensing Mistakes to Avoid
Physician licensing errors can delay practice, credentialing, and payer enrollment. Knowing the most common problems helps doctors and healthcare organizations maintain accurate licensing records and avoid preventable compliance issues.
Assuming One State License Covers Every State
A physician should not assume that a valid license in one state authorizes practice nationwide. Generally, physicians need separate state authorization where they practice, subject to applicable exceptions and special pathways.
Treating Telemedicine as License-Free Practice
Providing care remotely does not automatically remove state licensing requirements. Physicians should check the rules of the state where the patient is located before delivering telehealth services.
Confusing Licensure With Board Certification
Board certification demonstrates specialty qualifications, but it does not provide legal authority to practice medicine. An active state medical license remains a separate requirement.
Missing Renewal Deadlines
Allowing a license to expire can interrupt clinical practice and create problems with credentialing and payer records. Practices should maintain expiration dates and renewal reminders for every state license.
Submitting Incomplete Applications
Missing transcripts, verification documents, examination records, or required disclosures can delay application processing. Physicians should review the state’s current checklist before submitting an application.
Assuming Requirements Are Identical Across States
Medical license requirements by state can differ in areas such as postgraduate training, examination history, documentation, and background checks. FSMB recommends confirming current requirements with the applicable state medical board.
Failing to Update Credentialing and Billing Records
A license change should be reflected in relevant provider records, credentialing files, payer information, and internal compliance systems. Outdated license data can create administrative and reimbursement problems.
Conclusion
Doctors generally need a valid medical license in each state where they practice, although specific exceptions and alternative pathways may apply. State requirements, telemedicine rules, and IMLC eligibility should be verified with the appropriate medical board.
For physicians and healthcare organizations, accurate license tracking supports compliant practice, credentialing, payer enrollment, and billing. Checking current state requirements before providing care can help prevent avoidable administrative and compliance issues.
FAQs
Do doctors need a separate license for each state?
Generally, yes. Physicians usually need an active medical license in each state where they practice, including many telemedicine situations.
Does a medical license transfer from one state to another?
A medical license generally does not transfer automatically between states. Physicians typically must apply for a new state license or use an available licensure pathway.
Do doctors need a license to provide telemedicine across state lines?
In many cases, Telemedicine rules can depend on the state where the patient is located, so physicians should verify the applicable requirements before providing care.
What is the Interstate Medical Licensure Compact?
The Interstate Medical Licensure Compact (IMLC) provides an expedited pathway for eligible physicians seeking licenses in participating jurisdictions. Each participating state still issues its own medical license.
Is board certification the same as a medical license?
No. A medical license grants legal authority to practice medicine in a jurisdiction, while board certification demonstrates specialty-specific qualifications and is a separate professional credential.
