Transfer Your Plumber License to Wisconsin: Reciprocity & Endorsement (2026)
Last verified: 2026-07-21 · source: Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing ↗
Wisconsin publishes no named partner list, but the Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing evaluates out-of-state plumbers for endorsement individually, crediting a comparable exam or documented experience. Wisconsin does NOT waive its journeyman plumber examination for any out-of-state applicant and has no reciprocity agreements; every applicant must pass the Wisconsin journeyman plumber exam. Out-of-state plumbers qualify to sit that exam by 'comity' — documenting an out-of-state 5-year apprenticeship (minimum 576 hours of related instruction), or having passed a journeyman exam in another state and practiced at least 5 years under a license the Department finds substantially similar to Wis. Stat. ch. 145 — so no fresh Wisconsin apprenticeship is required, but the Wisconsin exam is mandatory. Application fee: $180 ($180 journeyman plumber credential fee (4-year term) per the DSPS Trades fee schedule; a nonrefundable application fee and a journeyman examination fee are also collected and are calculated within LicensE (not itemized on the fee schedule). Master plumber term fee is $500).

Verdict
Licensure by endorsement
Wisconsin works case-by-case rather than from a published partner list, so the Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing's judgment on your specific license, exam history, and documented experience decides the outcome. Where the pathway is equivalency-based, the board is measuring your home state's standards and experience requirements against its own. Get any exam waiver or experience credit confirmed in writing before you rely on it — discretionary approvals are exactly the kind of thing that shifts between reviewers.
Wisconsin has no plumber reciprocity and never waives its journeyman exam; endorsement_available is true only because Wisconsin's 'comity' route credits an out-of-state apprenticeship and experience so an experienced out-of-state journeyman need not restart an apprenticeship — but the Wisconsin exam is mandatory for everyone, so reciprocity_partners is []. Eligibility turns on a case-by-case 'substantially similar' determination, not a bilateral named-state agreement. The $180 figure is the four-year journeyman plumber credential/term fee (the DSPS fee schedule lists it as the term fee); the initial application and examination fees are calculated in LicensE and are not separately itemized on an official page. Master plumber is a distinct, higher-fee credential ($500 term). No national plumber verification database exists; verification_system_url is DSPS's public credential search.
