Boards verify every license you have ever held, not the ones you list. A license you let lapse a decade ago will surface through primary source verification, and if you did not disclose it the problem is no longer the license — it is the omission.
Boards do not take your word for your licensing history. They check, at the source, and the check does not stop at the licenses you mentioned.
What primary source verification means
The board contacts each issuing authority directly and asks for the record. Not a copy you supply, not a database summary — the issuing board’s own answer about your status, your dates, and anything on your file.
Alongside that, boards query national databases including the National Practitioner Data Bank. Those are keyed to you, not to the list you provided.
Why an old lapsed license surfaces
Because it is still a record. A license you obtained for a rotation, a locum assignment, or a job you held for eight months in 2014 exists permanently in that state’s system.
People forget these genuinely. A temporary license from a training year, a state you were licensed in but never actually worked in, a license that lapsed quietly while you were focused on something else. None of that is dishonest. All of it will be found.
What actually changes the outcome
Disclose it and it is administrative. Boards see lapsed licenses every day; a lapse is not misconduct and nobody treats it as such.
Omit it and the question changes. The board is no longer asking about a license from 2014. It is asking why an application signed under penalty of perjury did not mention something the applicant knew or should have known. That is a question about reliability, and it is much harder to answer well.
If you have already filed
Amend it. In writing, to the board, before they raise it with you. A correction you volunteer is a correction. One that arrives after the board found the discrepancy is a response.
The difference between those two framings is worth more than almost anything else you can do at that stage.
Verification costs money and time in both directions
Every board that has ever licensed you charges to produce a verification, and each has its own request process and its own turnaround. A PA with four prior licenses applying to three new states is issuing twelve requests and paying twelve fees.
Issue them all in one sitting. Done reactively — as each new board asks — it becomes twelve separate reminders spread across months, and it is where multi-state applications quietly stall.
What the verification actually says
Not simply "licensed" or "not licensed." It reports dates, status, how the license ended, and anything on the file: conditions, actions, complaints resolved or pending.
Which means a verification can surface something you had forgotten was recorded. An old complaint that went nowhere may still appear, and it is far better to have mentioned it than to have a board read it first.
Training licenses and limited permits count
People consistently omit these. A limited permit held during a training year, a temporary license for a locum assignment, a license obtained for a rotation and never used — each is a license issued by a jurisdiction, each is in that state’s system permanently, and each is something the application asked about.
None of them is a problem to disclose. All of them are a problem to omit, because the omission is what changes the board’s question from what happened to whether you can be relied on.
Maintain it as a living document
Update the record every time you obtain or lose a license, not every time you apply somewhere. A file that is current is an afternoon of work once; a file reconstructed under deadline is a week of archaeology and the place errors get introduced.
Build the list once
Every jurisdiction that ever issued you anything: license number, dates, status, and how it ended. Include temporary permits, training licenses and limited permits, because boards count those.
Assemble it now, keep it, and reuse it. Every future application asks the same question, and a PA who answers from a maintained record answers consistently — which is itself something boards notice, because inconsistency across applications in different states is one of the things national databases make visible.
Common questions
- Do I have to disclose a lapsed license on a PA application?
- Yes. Applications ask for every license ever held in any jurisdiction, active or not. A lapsed license is unremarkable to disclose and serious to omit.
- How do boards find out about old licenses?
- Through primary source verification and national databases including the National Practitioner Data Bank. They query the source directly rather than relying on what you listed.
- What if I genuinely forgot a license?
- Contact the board and amend the application in writing before they raise it. A correction you volunteer reads very differently from one they discover.
- Does a lapsed license hurt my application?
- Rarely on its own. Boards see lapsed licenses constantly. What causes real problems is a lapse that was not disclosed, or one that lapsed while an investigation was open.
