Medical license verification: what the state board record shows and when to check again

A physician is booked to start a locum assignment on Monday. She holds licenses in four states, and the file that reached your credentialing team on Thursday contains a PDF of her wallet card. The example is invented to show the mechanism. Medical license verification for that file starts at the board that issued each license, and most of the work lies in reading what each board's record shows and deciding when to look at it again.

A copy of a card shows the license as it stood when the card was printed. The Centers for Medicare & Medicaid Services tells hospital surveyors to "Review a sample of personnel files to verify that licensure and/or other required credentials information is up to date" [1]. For the whole sequence from application to appointment, see the medical staff credentialing process.

Hospitals verify current licensure from the primary source at four named moments

The federal hospital rule is a single sentence in 42 CFR 482.11(c): "The hospital must assure that personnel are licensed or meet other applicable standards that are required by State or local laws" [2]. The CMS State Operations Manual lists "Evidence of current licensure" among the minimum credentials the medical staff examines, for appointments and reappointments alike [1].

The Joint Commission is more specific about timing. Element of performance 3 under its hospital standard MS.17.01.03, usually written MS.17.01.03 EP 3, requires the hospital to verify "in writing and from the primary source whenever feasible, or from a credentials verification organization" the applicant's "Current licensure at the time of initial granting, renewal, and revision of privileges and at the time of license expiration" [3].

Since January 1, 2026, the element has carried that number; before then it was MS.06.01.03 EP 6 [4]. The wider renumbering is set out in what Accreditation 360 changed.

These rules bind hospitals. No source read for this article addresses what binds a staffing agency as distinct from a hospital. The practical reading for an agency is that its client hospital's file has to meet them, so the medical license verification the agency hands over needs to carry the board's own result and the date it was obtained.

The issuing board is the primary source, and boards describe their lookups differently

The board that issued a license is the primary source for it. The Federation of State Medical Boards collects board data in its Physician Data Center, and its FAQ states: "State medical boards remain the primary source and contribute on a daily, weekly, monthly, or quarterly cadence" [5]. The same FAQ says the Physician Data Center "meets primary-source equivalent requirements for state medical board and federal sanctions" [5]. That claim is worded around sanctions. For whether a license is current today, the issuing board remains the place to check.

On its credentialing program page, the National Committee for Quality Assurance accepts verification "through the primary source, a recognized source or a contracted agent of the primary source" [6]. Boards describe their own lookups in different terms:

• The Oregon Medical Board: "Anyone can access the online License Verification Service to obtain primary source licensure verification, free of charge" [7].
• The Medical Board of California makes its primary source statement about its License Verification System, a subscription service for authorized users: "Information contained in LVS is considered by the Joint Commission to be the primary source verification of the Board's license records" [8].
• The Mississippi State Board of Medical Licensure offers a free search for members of the public and sells a "Professional Verification" at "$25 per verification" for "Hospitals, clinics, and credentialing entities needing an official one-time verification" [9].
• The Texas Medical Board describes its online lookup as the verification itself: "The verification contains identifying information previously verified by the TMB, as well as the current status of the license" [10]. The page does not use the phrase "primary source".

Four boards' descriptions do not show how the others describe theirs, and none of the accreditor or Federation pages consulted lists which boards' free lookups count as primary source verification. Read what the issuing board says about its lookup before relying on it, and record in the file which service was used and when.

What a medical license verification record shows

The Texas Medical Board publishes the fields its online verification carries: year of birth, license number, issuance date, expiration date, current status, disciplinary and non-disciplinary restrictions, specialties, school of graduation and current board action [10]. The status field gives values such as Active, Delinquent, Suspended, Cancelled and Retired, together with "the date the status was last updated" [10].

Texas also puts more than concluded orders in the board action section. The board says it "may include any formal complaints filed by TMB, as well as petitions and/or responses related to licensure contested matters, at the State Office of Administrative Hearings" [10]. Read that section alongside the status line, because it can show a matter still in progress. The board's lookup page also says that part of a physician profile is information the licensee reports and the board has not verified [11], so the file should rest on the board-verified fields.

In California, a license not renewed by its expiration date shows as "Delinquent" on the board's website [12]. The board's subscription system also lets authorized users check "whether a Health Facility/Peer Review Reporting Form (805 report) has been filed against a physician or podiatrist" [8].

Board certification verification is a separate check

Board certification verification follows its own route. The American Board of Medical Specialties points credentialers to ABMS Solutions to verify a certification and sends patients to a different lookup site [13]. ABMS Solutions says its data "comes directly from the 24 ABMS Member Boards" and that its CertiFACTS service offers daily database updates [14]. Certification is checked in addition to the license. Federal rules bar a hospital from making staff membership or privileges dependent "solely upon certification, fellowship, or membership in a specialty body or society" [15].

How long a medical license verification stays current

A verification is evidence of the license on the day it was run, and NCQA limits how long that evidence counts. Its September 2025 credentialing guide gives a license to practice verification 180 days under Credentialing Accreditation and 90 days under Credentialing Certification [16]. NCQA's November 2025 policy update dates its 180-day and 120-day limits on other items in the file to files processed on or after July 1, 2025, and carries no equivalent note for the license limits [17]. How the window is counted is covered in the recency clock on a credentialing file.

Expiration is the date a file can plan for. California physicians renew every two years, and the board's renewal page states the deadline precisely: "Licenses expire at 11:59 p.m. on the expiration date, which is the last day of the month in which it was issued. There is no grace period" [12].

Status changes are harder to plan for, because a license can be suspended or placed on probation between renewals. NCQA's guide describes its Accreditation program as including monthly monitoring of license expiration, among other items, between recredentialing cycles [16]. CMS recommends an appraisal of each practitioner at least every 24 months [1], and Joint Commission privileges run for no more than three years [3]. None of these sets how often an employer should check for a status change between renewals.

The National Practitioner Data Bank runs its own alerting service: Continuous Query sends an email within 24 hours of a report reaching the data bank [18]. On December 4, 2026, the data bank will merge Continuous Query and the Individual One-Time Query into a single service, NPDB Query, and Continuous Query enrollments will transfer to it automatically [18]. The mechanics are covered in how a license or exclusion status changes between checks.

A multi-state physician has a separate license and record in each state

The physician in the opening example holds four licenses, so her file needs four board records, each with its own expiration date. The Interstate Medical Licensure Compact does not merge them into one. The compact's commission states: "The licensing is all state-based. Physicians do not receive a 'Compact license' or a nationally recognized medical license through their participation in the Compact" [19]. Compact physicians "receive a separate notice from each state where they are licensed when it is time to renew that license" [19].

Telemedicine adds a state of its own. CMS guidance says that when practitioner and patient are in different states, the practitioner must be licensed, or meet the other applicable standards, in both the state where the practitioner is located and the state where the patient is located [1].

Boards share discipline with each other, sending it to the Federation of State Medical Boards "to distribute to other medical boards where a physician is licensed or seeking licensure" [20]. The file still needs each issuing board's own record. None of the sources behind this article gives the share of physicians who hold licenses in more than one state. Privileging also starts again at each facility, as set out in why locum tenens credentialing starts over at every facility.

Keeping license status in view once the file is approved

Medical license verification at onboarding leaves a dated record, and each license in the file keeps its own expiration date running after approval.

Credentially monitors license status and document expirations in the background, alerting your team when something changes or needs action. Each check is recorded as it happens, so ongoing compliance does not depend on someone remembering to look. The license monitoring page shows how this works for a credentialing team.

Health Carousel, a US staffing firm, doubled its credentialing output without expanding the team and brought license and credential updates in-house. Brittany, Director of Credentialing, described the change: "Previously, we outsourced or paid providers for updates on licenses and credentials. Now, with Credentially, it's all in-house" [21].

Check the license line in ten physician files

Pull ten current physician files and read the license line in each. For every license held, the file should show which board service was used, the date of the check, the status the board returned and the next expiration date. A copy of a wallet card with nothing from the board behind it is the first gap to close. Medical license verification is one line in a complete credentialing file, and the same test applies to the rest of it. Once the gaps are listed, see license monitoring on a demo.

Frequently asked questions

What counts as primary source verification of a medical license?

The board that issued the license is the primary source. The Joint Commission's hospital element MS.17.01.03 EP 3 calls for verification in writing and from the primary source whenever feasible, or from a credentials verification organization. The National Committee for Quality Assurance also accepts a recognized source or a contracted agent of the primary source. Record the board service used and the date.

Is a state medical board's free online lookup enough for medical license verification?

It depends on the board. The Oregon Medical Board says its free online service provides primary source verification. California says so of its subscription License Verification System, and Mississippi sells a $25 official verification alongside its free search. No accreditor or Federation page read for this article lists every board's position, so check the issuing board's own description.

How often should a physician's license be re-verified?

The Joint Commission names four moments for hospitals: initial granting of privileges, renewal, revision of privileges, and license expiration. NCQA's September 2025 guide treats a license verification as current for 180 days under Credentialing Accreditation and 90 days under Credentialing Certification. No source read for this article sets a frequency for checking status changes, such as a suspension, between renewals.

Does the Interstate Medical Licensure Compact give a physician one license for several states?

No. The Interstate Medical Licensure Compact Commission states that the licensing is all state-based and that physicians do not receive a compact license or a nationally recognized medical license. Each participating state issues its own license, renewed on that state's schedule. A credentialing file needs each license verified with the board that issued it.
