Verdict
Reciprocity agreement
North Dakota is on Montana's reciprocity list, which puts this move on the streamlined track — on two conditions. Your North Dakota license must have been earned by examination, not grandfathered in, and be active and in good standing; where it is, Montana waives its journeyman exam and the requirements below are what it still insists on. Montana waives its journeyman written and practical examinations for an applicant who took and passed both the written and practical journeyman exams in Oregon, Idaho, North Dakota, or South Dakota and holds an active license there with no complaints filed; every other out-of-state applicant must sit for the Montana journeyman written and practical exams. One caution: these agreements are directional and revocable.

What's different between North Dakota and Montana
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Montana. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
North Dakota to Montana (this page): Reciprocity agreement.
Montana to North Dakota (the reverse move): Reciprocity agreement.
The route is the same in both directions.
- Does coming from North Dakota matter?
Coming from North Dakota matters here: only 4 of 50 origins (the other 49 states and DC) get this result for a move into Montana.
The others get: licensure by endorsement (37) and no state license to transfer (9).
- Reciprocity agreements
Montana's reciprocity agreement list names 4 states (Oregon, Idaho, North Dakota, and South Dakota), including North Dakota.
North Dakota's reciprocity agreement list names 3 states (Minnesota, Montana, and South Dakota), including Montana.
- Application fee
Montana lists $400 for an out-of-state applicant and North Dakota lists $150–$250 for the reverse move; neither may be the full cost.
- Processing time
Montana lists up to 4 weeks; North Dakota has no verified processing-time figure on file, so the two cannot be compared here.
- Exam rules on record
Montana and North Dakota carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Montana (this move): Montana waives its journeyman written and practical examinations for an applicant who took and passed both the written and practical journeyman exams in Oregon, Idaho, North Dakota, or South Dakota and holds an active license there with no complaints filed; every other out-of-state applicant must sit for the Montana journeyman written and practical exams
- North Dakota (the reverse move): North Dakota waives its journeyman (and master) plumber examination for applicants who hold a current, good-standing license issued under the substantially-equivalent laws of Minnesota, Montana, or South Dakota; reciprocity requires a Certificate of Endorsement from the home-state board (Minnesota licenses must have been held at least one year, and South Dakota journeyman reciprocity additionally requires state residency). All other out-of-state plumbers must pass the North Dakota journeyman written and practical examinations.
What changes, North Dakota → Montana
| North Dakota (current) | Montana (destination) | |
|---|---|---|
| Application fee | $150–$250 ($50 application fee (N.D. Admin. Code 62-02-01-01) plus the license fee — journeyman $100 (total $150) or master $200 (total $250, statutory maximums under NDCC ch. 43-18); a separate $50 examination fee applies only to applicants who must test, so reciprocity (endorsement) applicants avoid it) | $400 (Reciprocity path: $400 total ($100 application fee + $300 reciprocity fee). The examination path is instead $270 ($100 application + $170 license). Optional $100 temporary journeyman work permit if requested) |
| Processing time | No board-stated processing time; examination applicants are tested at the next regular board meeting | up to 4 weeks (Board states complete, routine applications are processed within 30 days (about 4 weeks); non-routine applications requiring Board review take longer, and applicants are notified of status within 30 days of receipt) |
| Licensing authority | North Dakota State Plumbing Board | Montana Board of Plumbers — Department of Labor and Industry, Business Standards Division |

Frequently asked questions
Can I keep my North Dakota plumbing license after I'm licensed in Montana?
Yes — plumbing licenses in different jurisdictions run independently. Keep the North Dakota credential active on its own renewal and continuing-education schedule and you hold both, which is common for plumbers working near a state line.
