Verdict
Full re-application
There is nothing at the state level to transfer your Michigan license into: Missouri issues no statewide plumbing license, so plumbers there are licensed at the contractor level or by cities and counties. Not applicable — Missouri issues no state-level plumber license; each city or county board of examiners sets its own examination, so there is no statewide credential to transfer and no state exam to waive. The move is a local or contractor-board application, not a reciprocity filing — identify the authority that governs your worksite and work from its exam, experience, and fee rules. Your Michigan license may count toward a local experience requirement, but Missouri has no state credential for it to reciprocate into.
