California to Indiana: journeyman plumber license reciprocity
California does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Indiana's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Commission review of out-of-state journeyman credentials (IC 25-28.5-1-19; no named partner states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
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).

How Indiana licenses journeyman plumbers
Indiana journeyman plumber · “Journeyman Plumber”
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).

Licensed by cities and counties
Issued by City and county building departments (no statewide journeyman plumber license)
California does not issue a statewide journeyman plumber or master plumber license. The only state plumbing credential is the C-36 Plumbing Contractor classification from the Contractors State License Board (CSLB), which is a contractor license qualified by a named individual, not a personal tradesperson card. Business and Professions Code §7053 takes wage employees outside the Contractors State License Law, so a plumber who works for a C-36 contractor needs no CSLB license; California's personal electrician certification (Labor Code §108) has no plumbing counterpart. Some cities and counties still examine and card journeyman plumbers (certificate of competency / journey-level plumber) for work in that jurisdiction. Those cards are not statewide, are not issued by CSLB, and an out-of-state journeyman plumber license is not recognized by any state board. An arriving journeyman should ask the building department where the job is whether a local plumber card is required and sit that city's exam; contracting independently requires a C-36 license, described at the master level.
How local licensing works in California
No state journeyman. CSLB's C-36 page and fee/reciprocity materials describe only contractor licensing. B&P §7053 leaves employed plumbers unlicensed at the state level. There is no DIR-style plumber certification.
How local cards work. Cities that still license individual plumbers typically issue a certificate of competency or journey-level plumber card after documented experience and a local exam. The card does not authorize contracting (that is C-36). Cards are not portable statewide; a Los Angeles card does not satisfy San Francisco, and vice versa. Other cities and some counties may also card plumbers; ask the building department where the job is for its current rules.

- San Francisco (Department of Building Inspection - certificate of competency)
