Mississippi to Indiana: journeyman plumber license reciprocity
Mississippi 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, so every out-of-state journeyman is handled under the same Commission review (Endorsement, not Reciprocity). IC 25-28.5-1-19 provides that a journeyman plumber licensed in another state shall without examination be granted an Indiana journeyman license of the same category if the applicant is at least 18, the origin requirements were substantially equal at the time of last licensing, and the same privilege is accorded to Indiana licensees. The applicant files a Journeyman Plumber application in MyLicense One with origin-licence verification. If mutual privilege is not shown, the Commission may still require the Indiana journeyman examination administered by PROV. Licence issuance fees depend on whether the licence is issued in an odd or even year.
Mechanism stays Endorsement because no named partner states were published; Reciprocity is reserved for exam-waived named origins. examTradeRequired is false because IC 25-28.5-1-19 is an exam waiver conditioned on substantial equality and mutual privilege, not an automatic partner list. Do not invent partner states.

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 licences to individuals, a Temporary Plumbing Contractor licence, and a Corporate Plumbing Business registration for entities. Applications, renewals and licence 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 licence fees are prorated by whether the licence 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 a nonresident provision (IC 25-28.5-1-12), so an out-of-state journeyman applies to the Commission rather than to any city or county.
Why Mississippi has nothing to transfer

Licensed by cities and counties
Mississippi does not issue a journeyman plumber license. The Mississippi State Board of Contractors (MSBOC) licenses contracting businesses - commercial contractors and subcontractors on jobs over $50,000 and residential contractors and residential plumbing subcontractors above the residential thresholds - through a Certificate of Responsibility held by the company with a tested qualifying party, and its FAQ states that it does not license individual journeymen; none of its Plumbing, Mechanical or Residential Plumbing classifications, exams or reciprocity agreements apply to a plumber who only wants to work for an employer. Individual plumbers are licensed, where they are licensed at all, by cities under their own ordinances: Southaven's Building Department issues apprentice, journeyman and master trade licenses and accepts a current journeyman license from another jurisdiction or a passed ICC journeyman exam in place of its own testing, while coastal cities such as Gulfport license only the contractor's qualifying party and have no journeyman card. An out-of-state journeyman plumber license therefore has no state-level recognition in Mississippi; the plumber must check the ordinance of each city where they will work and apply locally, and Southaven-style acceptance of another jurisdiction's card or an ICC score is the closest thing to reciprocity that exists.
How local licensing works in Mississippi
How local licensing works. Mississippi's contractor law (Miss. Code Title 31 ch. 3 for commercial work, Title 73 ch. 59 for residential work) is enforced by MSBOC at the business level: a commercial license is required for every contractor and subcontractor on commercial jobs over $50,000, and residential plumbing subcontractors need a residential license on new homes over $50,000 or remodels over $10,000. Those licenses attach to the company and its qualifying party, not to journeymen, and no statute standardizes city trade cards. Journeyman licensing is a municipal matter and varies by city; many cities have no journeyman card at all and simply require plumbers to work under a licensed contractor.
Southaven. The Building Department's Application for License covers Apprentice ($20), Journeyman ($50) and Master ($100) trade licenses. A journeyman applicant files the application with photo ID and either a copy of a current, active journeyman license held in another jurisdiction or written proof of passing the ICC journeyman exam; no Southaven exam is given, so an out-of-state journeyman card or ICC plumbing score substitutes for local testing. The city refers all questions about out-of-state reciprocity to MSBOC. There is no journeyman license; plumbers work under the licensed contractor.
Jackson, Hattiesburg, Biloxi, Tupelo. These cities license contractors and, in some cases, trades under their own ordinances, but no official page publishing a journeyman plumber card could be opened in this pass: the Jackson contractor-licensing URL redirected to a map embed and the Hattiesburg plumbing ordinance PDF returned 404. In practice a journeyman card from another jurisdiction or a passing ICC journeyman plumbing score is accepted by Southaven, and elsewhere the plumber simply works under a locally licensed contractor.

Common questions
- Do I have to take the Indiana journeyman plumber exam if I'm licensed in Mississippi?
- No. The trade exam is waived on this path.
- Do my Mississippi work hours count in Indiana?
- Yes. Documented out-of-state experience counts toward Indiana's eligibility requirements.
- Does it work the other way, from Indiana to Mississippi?
- Not necessarily. Reciprocity is directed. Going from Indiana to Mississippi, the mechanism is not applicable.
