No, Montana no longer requires boat validation stickers. As of May 1, 2025, Montana Fish, Wildlife & Parks (FWP) eliminated the validation sticker requirement entirely. You do not need to display one, renew one, or track an expiration date. Three things still matter:
- What you still need: The white permanent "PERM" decal issued by your County Treasurer, your registration numbers displayed correctly on the bow, and your certificate of number on board.
- Where to get your decal: Your County Treasurer's office handles registration and issues the permanent decal; Montana FWP and MVD (MVDMT.gov) provide guidance and online resources.
- Quick action: Check that your registration numbers are legible, at least 3 inches tall, and that your PERM decal sits on the port (left) side, 3 inches behind the number.

What does Montana law require for boat registration now?
Montana requires permanent registration for all motorboats, personal watercraft (PWCs), and motorized pontoons operated on state waters. The County Treasurer in your county of residence issues the white permanent decal labeled "PERM," and that decal is valid for the life of the vessel as long as ownership does not change. Under § 61-3-321(10)(a)(i), MCA, registration is a one-time obligation tied to the vessel, not an annual renewal cycle.
Registration fees by vessel length (one-time charge):
| Vessel Length | One-Time Registration Fee |
|---|---|
| Under 16' | $65.50 |
| 16'–under 19' | $125.50 |
| 19' or longer | $295.50 |

Your certificate of number must be pocket-size and available for inspection by any federal, state, or local law enforcement officer whenever the vessel is on Montana waters. The permanent registration decal does not expire while the vessel stays under the same ownership. Sell the boat, and the new owner must register it and obtain a new PERM decal before operating it.
Why did Montana drop the validation sticker in 2026?
The short version: the federal government changed the rules, and Montana decided the simplest response was to drop the sticker entirely.
Montana FWP announced that changes in U.S. Coast Guard funding requirements would have forced the state to switch from its existing 3-year validation sticker cycle to an annual validation requirement. Rather than impose that administrative burden on boaters, Montana eliminated the validation sticker requirement altogether, effective May 1, 2025.
From Montana FWP (June 18, 2025): Montana Fish, Wildlife & Parks confirmed that validation decals are no longer required for watercraft in Montana, citing the administrative burden and changes in Coast Guard funding rules as the reason for the policy change. All other boating rules — including life jacket requirements and aquatic invasive species (AIS) inspections — remain fully in effect.
If you have an old 3-year validation sticker on your hull, you are not required to remove it, but it carries no ongoing display obligation. Older FWP guidance referencing 3-year validation decals is now superseded. If an inspector ever asks about historic validation, FWP is the right contact to confirm your record.
How to register your boat and get the permanent PERM decal
Registration happens at your County Treasurer's office, not online through a state portal. Here is the process:
- Gather your documents. Bring the vessel title (or bill of sale for a new purchase), a valid government-issued ID, and proof of Montana residency.
- Visit your County Treasurer. Find your county treasurer location on MVDMT.gov. This is where you pay the one-time registration fee and receive your certificate of number.
- Receive your PERM decal. The County Treasurer issues the white permanent decal at the time of registration. No separate order or waiting period.
- Mount the decal correctly. Port side, 3 inches aft of your registration number. More on exact placement below.
- Keep your certificate on board. Pocket-size, accessible for inspection any time the vessel is on state waters.
For replacement decals (lost, damaged, or stolen), contact your County Treasurer's office directly. Bring your certificate of number and ID. If a decal is stolen, report it to local law enforcement and bring the report number when requesting a replacement.
Pro Tip: Order your registration number decals before your first launch of the season. If the numbers on your hull are faded or peeling, you are a citation risk even if your PERM decal is perfectly placed.
- Montana FWP regional offices can answer questions about display rules and enforcement.
- MVD handles administrative registration questions at MVDMT.gov.
- Your County Treasurer handles all in-person transactions: new registration, transfers, and replacements.
Exactly where do registration numbers and the PERM decal go?
Montana's display rules come straight from § 23-2-512, MCA and the 2025 FWP boating laws PDF. Get these wrong and you risk a citation regardless of whether your registration is current.
Number format and size:
- Start with "MT" followed by a space or hyphen, then your number suffix: MT 234 ABC or MT-234-ABC are both acceptable.
- Letters and numbers must be vertical block style, at least 3 inches tall.
- Color must contrast with the hull. White numbers on a white hull are not compliant.
- No extra letters, numbers, or decorative elements near the bow that could be confused with the registration number.
Placement:
- Numbers go on both outboard sides of the forward half of the vessel.
- The PERM decal goes on the port (left) side only, exactly 3 inches aft of the registration number.
- Numbers must read left to right and be clearly visible from the water.
Common mistakes that lead to citations:
- Placing the PERM decal on the starboard (right) side instead of port.
- Using low-quality vinyl that fades or peels within a season, making numbers illegible.
- Mounting numbers too low, near the waterline, where they are obscured when the vessel is underway.
- Adding decorative graphics that visually crowd or partially cover the registration numbers.
Pro Tip: Take a photo of your bow from 50 feet away. If you can't read the numbers clearly in the photo, an enforcement officer on the water won't be able to either.
What are the penalties for non-compliance, and who enforces the rules?
Montana Fish, Wildlife & Parks watercraft inspectors are the primary enforcement presence on state waters. County law enforcement and MVD provide administrative oversight. Under Montana law, failure to pay the required registration fees is a misdemeanor, and the penalty is a fine equal to four times the applicable registration fee.
Who to contact and when:
- Montana FWP regional offices: Questions about display rules, AIS inspections, life jacket requirements, or enforcement disputes. fwp.mt.gov
- MVD (MVDMT.gov): Registration questions, title transfers, and statutory references. mvdmt.gov
- County Treasurer: Lost or damaged decal replacement, new registration, ownership transfers. Find your county
Other safety rules are unchanged by the 2025 sticker policy. Life jacket requirements, AIS inspection stations, and no-wake zone rules all remain fully in force. Dropping the validation sticker did not relax anything else.
What materials should you use for registration numbers and decals?
The PERM decal itself comes from the County Treasurer, but your registration numbers are your responsibility. This is where material choice matters more than most owners realize.
Marine-grade, UV-resistant vinyl is the right call for Montana conditions. Sun exposure on Flathead Lake or Holter Reservoir will destroy standard vinyl within a season or two. Faded, peeling numbers are the most common reason boaters get cited for display violations, not missing paperwork. Poor-quality vinyl also tends to lift at the edges, trapping water and accelerating the peel.
Application checklist for lasting results:
- Clean and de-wax the hull surface before applying any decal.
- Apply at the recommended temperature range (typically 50°F–90°F) for proper adhesion.
- Use a squeegee to push out air pockets from the center outward.
- Allow full cure time before launching, usually 24–48 hours.
- Inspect decals at the start of each season and after any significant impact or grounding.
Registrationdecals.com offers marine-grade, UV-resistant vinyl registration decals with an online design tool that lets you enter your Montana registration number, choose your font, and select a contrasting color in minutes. Production runs 3–5 business days with free shipping to contiguous U.S. addresses. For guidance on how long properly applied marine vinyl holds up, their decal longevity resource is worth a read before you order.
Pro Tip: Order a spare set of registration number decals when you place your initial order. If one side gets damaged mid-season, you won't have to wait for a reorder before your next launch.
Pairing quality materials with correct application is also a small sustainability win. Decals that last longer mean less vinyl waste and fewer reorders. For broader context on responsible boating practices, sustainable boating guidance covers material care alongside other environmental considerations.

The part most Montana boaters are getting wrong
The 2025 change is genuinely good news, but it has created a blind spot. Because the headline is "you no longer need a sticker," some owners are treating it as a general relaxation of boating rules. It is not. The PERM decal requirement, the number display specs, and the certificate-of-number obligation are all unchanged. What changed is one administrative layer.
The real compliance risk in Montana has always been number legibility, not sticker status. FWP inspectors on the water are not primarily checking for a validation sticker; they are checking whether your registration numbers are readable, correctly placed, and the right size. A boat with a current PERM decal and faded, 2-inch numbers is still a citation waiting to happen.
Owners who have been running the same vinyl numbers for five or more seasons should treat this spring as a good moment to inspect them honestly. If the edges are lifting or the color has washed out, replace them before you launch. The fee is small. The fine for non-display is four times your registration fee.
