No state license — city/county licensing
No state plumbing board — licensing is by city and county only runs plumbing licensing in Missouri. Below: the exact ladder, the transfer doors into Missouri from all 50 states, the renewal and lapse lines, and the master-of-record rule for opening a company — every figure from the board's own publications, checked October 22, 2026.
No state license — city/county licensing Checked in part Checked October 22, 2026
Checked in part. No Missouri state agency licenses plumbers and there is no state statute page to cite for a state license; the 'none' model is confirmed by the absence of any state licensing program and by Missouri contractor guidance that licensing is local. Local requirements cited are the well-documented licensing jurisdictions (St. Louis County Board of Plumbing Examiners, City of St. Louis, Kansas City); individual local hour/exam figures were not verified city-by-city in this batch.
No state plumber license. Missouri does not license plumbers at the state level — there is no state journeyman or master license to apply for. Licensing is done by cities and counties, and the local rules are the real rules where you work.

Registration, in the board’s terms: Missouri has no state-approved licensing regulations for plumbers and no state apprentice registration. Licenses are issued on a local level — e.g. St. Louis County (Board of Plumbing Examiners), the City of St. Louis, Kansas City, Columbia, St. Charles County, Jefferson City, Cape Girardeau and Springfield-area jurisdictions each run their own journeyman/master programs with their own experience and exam rules.
No state master plumber license (local licenses only): No state requirement. Master plumber licenses are issued by individual cities/counties (for example St. Louis County and Kansas City) under local ordinances, typically after journeyman experience and a local master examination.
There is no Missouri master plumber license to reciprocate or renew at state level.
There is no state license to lapse. Local license renewal, late-renewal and re-examination rules are set by each issuing city/county.
Reinstatement: Governed by the issuing local jurisdiction only.
Past the line: Governed by the issuing local jurisdiction only.
There is no Missouri state license to endorse into — licensing is local, and local boards weigh verified out-of-state experience case by case. No state reciprocity is possible because Missouri issues no state plumbing license; any recognition between local jurisdictions is a local-board decision.

Included in the $49 PlumberLicenseCheck Kit
One payment. Yours to keep. The checkers above stay free either way.
The seat: None at state level (local master/contractor requirements vary). Missouri imposes no statewide master-of-record, bond or insurance gate for plumbing businesses; cities and counties that license plumbing contractors set their own qualifying-individual and bond rules (Kansas City, St. Louis County and Springfield are common examples).
Do not mistake 'no state license' for 'no license anywhere': most larger Missouri cities and St. Louis County require local journeyman/master licensure and permits, and working across a county line can mean a second license. Missouri does have an OPTIONAL statewide electrical contractor license (OSEC) — there is no plumbing equivalent.
