Verdict
Full re-application
There is nothing at the state level to transfer your Pennsylvania 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 Pennsylvania license may count toward a local experience requirement, but Missouri has no state credential for it to reciprocate into.
What changes, Pennsylvania → Missouri
| Pennsylvania (current) | Missouri (destination) | |
|---|---|---|
| Application fee | No statewide fee. Fees are set locally; for example, Philadelphia's journeyman plumber license is $126 initial (including a $25 non-refundable application fee) and $126 annual renewal. | No state fee — plumber licensing fees are set by each local jurisdiction and vary; consult the specific city or county board |
| Processing time | No statewide process; processing time is set by each municipality. | No statewide process; timelines are set by each local board (e.g., the St. Louis Board of Examiners reviews applications at its monthly board meetings) |
| Licensing authority | No statewide board — plumber licensing is handled by Pennsylvania municipalities (e.g., Philadelphia Department of Licenses & Inspections; Allegheny County Health Department for the Pittsburgh area) | No state plumbing board — the Missouri Division of Professional Registration does not license plumbers; licensing is local (e.g., St. Louis Board of Examiners of Plumbers and Drainlayers) |
The destination column is what you must satisfy — Missouri sets the rules for this move.
