Pennsylvania to Indiana: master plumber license reciprocity
Pennsylvania does not issue a statewide master 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 master/contractor 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.
An out-of-state master plumber or plumbing contractor applies to the Indiana Plumbing Commission for a Plumbing Contractor licence through MyLicense One. Indiana names no reciprocal partner states, so the path is Endorsement under IC 25-28.5-1-19: a plumbing contractor licensed in another state shall without examination be granted an Indiana Plumbing Contractor licence of the same category if the applicant is at least 18, the origin requirements were substantially equal at last licensing, and the same privilege is accorded to Indiana licensees. If mutual privilege is not shown, the Commission may require the Indiana Plumbing Contractor examination administered by PROV. A licensee who will operate through a corporation, partnership or association must additionally register the entity as a Corporate Plumbing Business. Initial fees are prorated by odd or even issuance year.
Same as journeyman: mechanism Endorsement (no named partners); examTradeRequired false because IC 25-28.5-1-19 waives the exam when substantial equality and mutual privilege are shown. IC 25-28.5-1-12 still unread, so the four-years-as-journeyman contractor prerequisite is not asserted as a numeric condition on this inbound path.

How Indiana licenses master plumbers
Indiana master plumber · “Plumbing Contractor”
Statewide license
Issued by Indiana Plumbing Commission (Indiana Professional Licensing Agency)
Indiana has no 'master plumber' licence. The top individual credential is the Plumbing Contractor licence issued by the Indiana Plumbing Commission (PLA) under IC 25-28.5-1, which is held by a person who has qualified by experience and passed the Indiana plumbing contractor examination administered by PROV; this file maps it to the master level because it is the credential that authorises a plumber to contract for and supervise plumbing work. A corporation, partnership or association that performs plumbing work registers separately as a Corporate Plumbing Business, and the Commission also issues a Temporary Plumbing Contractor licence (IC 25-28.5-1-18.5). Applications and renewals are processed in MyLicense One, and initial licence issuance fees are prorated by odd or even issuance year. The reciprocity section of the statute (IC 25-28.5-1-19) applies to out-of-state master or contractor licensees in the same way as to journeymen.
Why Pennsylvania has nothing to transfer
Pennsylvania master plumber · “Master Plumber (city-issued; no state licence)”
Licensed by cities and counties
Pennsylvania issues no statewide master plumber or plumbing-contractor licence; none of the Department of State's 29 boards covers the trade, so the master-level credential exists only in cities that have chosen to license it. Allentown posts a 2026 Master Plumber Exam Application and requires a separate business licence to contract. Harrisburg posts a plumbing licence application whose master-versus-journeyman split was not verified. Pittsburgh's plumbing trade-licence page 404'd. There is no state-level recognition of an out-of-state master plumber licence and no municipal programme verified here that waives the plumbing trade exam. An arriving master should expect to apply city by city, document local experience thresholds, and sit each city's exam (ICC or city-written) unless that city later publishes an exam-waiver rule.
How local licensing works in Pennsylvania
How local licensing works. With no state plumbing board, each Pennsylvania city that licenses master plumbers does so under its own ordinance. The journeyman card, where it exists, does not authorise pulling permits or running a shop; the master (or master-contractor) licence does. A master licence is valid only in the issuing city. The journeyman page states that a journeyman works 'under a licensed master plumber' and may not operate a business, which implies the master licence is the contracting credential. Other PLI trade licences are issued to individuals, expire 365 days from issue, and (for electrical and mechanical) accept ICC master exams for any code year plus a stated experience total; whether plumbing follows that pattern is unverified. 2025 plumbing licence fee unknown.
Allentown. 2026 Master Plumber Exam Application is posted under Professional Trades Licensing. Contracting requires the trades licence and a city business licence. Reciprocity not mentioned on the landing page. Electrical Option B on that same form (eight years in lieu of exam) must not be assumed to apply to plumbing.
Inbound master. No Pennsylvania state licence and no verified exam-waiver reciprocity. Plan on a new application in each city where permits will be pulled. Philadelphia is the most fully documented shop: obtain the Master Plumber's License after (typically) holding or qualifying beyond the journeyman ICC path; confirm current master fees and exam on the master service page before applying. Allentown requires its master plumber exam application plus a business licence. Scranton uses the 2021 master contractor packet. Statewide reciprocity: none.
Common questions

- Do my Pennsylvania 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 Pennsylvania?
- Not necessarily. Reciprocity is directed. Going from Indiana to Pennsylvania, the mechanism is not applicable.
