Mississippi to Maine: journeyman plumber license reciprocity
Mississippi does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Maine'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.
Licensure by endorsement (32 M.R.S. §3501-C); examination if origin requirements are not substantially equivalent
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Maine has a statutory endorsement path for plumbers and no published list of signed reciprocity partners was found. Under 32 M.R.S. §3501-C the Plumbers' Examining Board must establish licensure by endorsement in accordance with 10 M.R.S. §8003-H: an applicant who holds a substantially equivalent journeyman-level license in another U.S. jurisdiction, is in good standing everywhere licensed, and pays the fee may be licensed without sitting Maine's journeyman examination, unless a jurisprudence exam is required by law or rule (none is identified in chapter 49). An applicant whose origin license is not substantially equivalent applies under §3501(1-A) and (2): sworn application, §3501-B fee, documented 4,000 hours (or 2,000 journeyman-in-training hours) or the equivalent, and a passing grade on the board-approved journeyman exam. Out-of-state hours can count as 'the equivalent' of licensed trainee time. No municipal plumber license is a Maine credential.
Fee, eligibility details, and processing steps are not published in a form we can list here. Please see the sources on this page to find out more.

How Maine licenses journeyman plumbers
Maine journeyman plumber · “Journeyman Plumber”
Statewide license
Maine issues a statewide Journeyman Plumber license through the Plumbers' Examining Board in OPOR (32 M.R.S. ch. 49). By examination an applicant files a sworn application, pays the fee set under §3501-B, documents at least two years / 4,000 hours as a licensed trainee plumber under a master (or the equivalent), or 2,000 hours as a journeyman-in-training under a master within four years of the JIT license, and obtains a passing grade on the board-approved journeyman examination. The board also issues a one-time, four-year nonrenewable journeyman-in-training license after one academic year of approved plumbing instruction plus the same exam, a limited plumber license, and a trainee plumber license without examination. Out-of-state journeymen are directed to licensure by endorsement under 32 M.R.S. §3501-C and 10 M.R.S. §8003-H when the origin jurisdiction's requirements are substantially equivalent; otherwise they apply by examination with comparable hours credited as 'the equivalent' of Maine trainee time.
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 Maine 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 Maine?
- Yes. Documented out-of-state experience counts toward Maine's eligibility requirements.
- Does it work the other way, from Maine to Mississippi?
- Not necessarily. Reciprocity is directed. Going from Maine to Mississippi, the mechanism is not applicable.
