Last verified: 2026-07-21 · source: Indiana Professional Licensing Agency (PLA) — Indiana Plumbing Commission ↗
A plumbing license transfers from Illinois to Indiana by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Indiana Professional Licensing Agency (PLA) — Indiana Plumbing Commission, verify your Illinois license, and meet Indiana's endorsement requirements. Indiana Code 25-28.5-1-19 (verified current as of 2026-01-01) provides that an out-of-state journeyman plumber 'shall without examination, be granted a license' by the Indiana Plumbing Commission IF the other jurisdiction's licensing requirements were substantially equal to Indiana's when the applicant was last licensed AND that jurisdiction grants Indiana licensees the same reciprocal privilege; the statute names no partner states and no official list of qualifying states was located, so an applicant must confirm eligibility with the Commission, and anyone who does not meet the substantial-equivalence/mutuality test must be approved by the Commission and pass the Indiana journeyman plumber examination.

Verdict
Licensure by endorsement
Illinois is not among the states Indiana names for an automatic exam waiver, so this move runs on the Indiana Professional Licensing Agency (PLA) — Indiana Plumbing Commission's individual endorsement or equivalency review rather than a guarantee. Indiana Code 25-28.5-1-19 (verified current as of 2026-01-01) provides that an out-of-state journeyman plumber 'shall without examination, be granted a license' by the Indiana Plumbing Commission IF the other jurisdiction's licensing requirements were substantially equal to Indiana's when the applicant was last licensed AND that jurisdiction grants Indiana licensees the same reciprocal privilege; the statute names no partner states and no official list of qualifying states was located, so an applicant must confirm eligibility with the Commission, and anyone who does not meet the substantial-equivalence/mutuality test must be approved by the Commission and pass the Indiana journeyman plumber examination. Bring your Illinois license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
