Minnesota to Indiana: journeyman plumber license reciprocity
Indiana has no reciprocity agreement with Minnesota. A Minnesota journeyman plumber applies by endorsement.

Commission review of out-of-state journeyman credentials (IC 25-28.5-1-19; no named partner states)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
Indiana publishes no list of reciprocal partner states for plumbing, and the Plumbing Commission's FAQ states that reciprocity is not available for journeyman plumbers: an out-of-state journeyman files an application, the Commission reviews it, and an approved applicant must pass the Indiana exam. IC 25-28.5-1-19 allows a license without examination where the origin state's requirements were substantially equal and that state grants Indiana licensees the same privilege, but the Commission's published process routes out-of-state licensees to the exam. You file a Journeyman Plumber application in MyLicense One with certification of your out-of-state license and an employer affidavit showing four years of experience in the plumbing trade, then schedule the 90-question Indiana Journeyman Plumber exam with Prov. The application fee is $30, and the initial license fee is $30 if the license is issued in an even-numbered year or $15 in an odd-numbered year.
Indiana's statute provides for licensing without examination for holders from states with a reciprocity agreement or substantially equal requirements (IC 25-28.5-1-12(e) and -19), but the Commission names no such states and its FAQ says reciprocity is not available. Under IC 25-28.5-1-12(d), a license from a state without a reciprocity agreement makes the holder eligible to take the Indiana exam; an applicant from a state that does not license plumbers must instead meet Indiana's apprenticeship or experience requirements. Nonresident licensees must also appoint the Commission's secretary as agent for service of process (IC 25-28.5-1-20).

Statewide license
Issued by Indiana Plumbing Commission (Indiana Professional Licensing Agency)
Indiana licenses plumbers statewide through the Indiana Plumbing Commission, which is administered by the Professional Licensing Agency (PLA) under IC 25-28.5-1. The Commission registers Plumbing Apprentices and approves apprenticeship programs and schools, and it issues Journeyman Plumber and Plumbing Contractor licenses to individuals, a Temporary Plumbing Contractor license, and a Corporate Plumbing Business registration for entities. Applications, renewals and license verification are handled online in MyLicense One with an Access Indiana account. The Indiana journeyman examination is administered by the testing vendor Prov, and initial license fees depend on whether the license is issued in an odd or even year of the two-year cycle. Indiana's statute contains a reciprocity section (IC 25-28.5-1-19) and nonresident provisions (IC 25-28.5-1-12(d) and -20), so an out-of-state journeyman applies to the Commission rather than to any city or county; cities may require a licensed plumber to register but may not require any other license (IC 25-28.5-1-33).
