Transfer Your Plumber License to Mississippi: Reciprocity & Endorsement (2026)

The structural fact first: Mississippi does not issue a statewide journeyman plumber license, so "which board do I apply to" has no state-level answer and there is no state credential to carry across. Your first task is to identify the authority that governs the jobsite — a contractor-level board, or the city or county where you will work — and read its exam and experience rules directly. Just as important on the way out: a credential earned under Mississippi's regime generally will not satisfy another state's condition that you hold a state license earned by examination, so expect new-applicant treatment if you later move to a state that does license at the state level. Treat the notes below as directions to the right authority, not a transfer checklist.

Mississippi has no state-level individual journeyman or master plumber license — the canonical credential for this dataset does not exist here; individual plumbers are regulated (if at all) by municipalities. The only state plumbing credential is the MSBOC contractor Certificate of Responsibility for companies (commercial work over $50,000; residential plumbing of $10,000 or more). MSBOC contractor reciprocity waives only the trade exam and varies by classification; all applicants must still pass the Mississippi Law and Business Management exam. MSBOC runs a public contractor license search at http://search.msboc.us/ConsolidatedSearch.cfm, but there is no state individual-plumber lookup, so verification_system_url is null.
