Buying or registering a trailer in New Hampshire? Three different stickers and plates need to be in the right places: the federal utility trailer VIN lettering/MFR plate, the state registration tag, and (if you run commercial) any DOT or company markings. This guide walks through placement, replacement, and what vinyl to use so your markings survive cold weather vinyl performance New England winters and road salt.
Federal VIN / MFR Plate
Every enclosed trailer lettering manufactured for road use must carry a federal VIN/Manufacturer plate. The standard factory location is the front-left frame rail or tongue, riveted or adhered. If yours has been ground off or stolen, contact the New Hampshire State Police (Troop G. Commercial Vehicle Enforcement) or New Hampshire DMV to start a replacement-VIN process. Hoosier Decal does not produce state VIN tags.
New Hampshire Registration Plate Placement
New Hampshire trailer license plates mount on the rear of the trailer, illuminated by a working tag light at night. Some New Hampshire trailer classes also issue a small registration sticker that goes on the plate itself. Check your renewal notice for the exact placement window.
- Cargo / enclosed: rear door, centered, illuminated
- Utility / open: rear cross member, drilled mount
- Gooseneck / fifth-wheel: rear cross member, often offset to clear ramps
USDOT & Company Markings on Trailers
FMCSA marking requirements 390.21 requires USDOT markings on the power unit, not the trailer. Many New Hampshire fleets still letter their trailers for brand visibility:
| Marking | Required? | Typical placement |
|---|---|---|
| VIN / MFR plate | Yes (federal) | Front-left frame rail |
| State registration plate | Yes | Rear, illuminated |
| USDOT number on trailer | No (federal); fleet choice | Side panel, 2″–3″ letters |
| Company name / phone | Optional | Side panel, 6″–12″ letters |
Replacing a Worn or Missing Decal
State-issued plates and registration stickers must come from the New Hampshire agency. For company name, phone, USDOT number, or unit numbers, Hoosier Decal can reprint to match the original layout: or upgrade to premium vinyl that lasts 2–3 seasons longer than the original.

- Premium: 6-mil cast vinyl + UV laminate, 6–7 years
- Standard: 3-mil calendared vinyl, 3–4 years
- Reflective: engineer-grade reflective for night visibility on heavy haul
Frequently Asked Questions
Where does the VIN sticker go on a New Hampshire trailer?
Most New Hampshire trailer manufacturers place the federal VIN/MFR plate on the front-left frame rail or tongue. If yours is missing, the state issues a replacement VIN tag through the New Hampshire State Police (Troop G. Commercial Vehicle Enforcement) or DMV equivalent. Hoosier Decal does not print state-issued VIN tags.
Do I need a USDOT number on my trailer in New Hampshire?
FMCSA 390.21 places the USDOT marking requirement on the power unit, not the trailer. Some interstate operations choose to also mark trailers for fleet identification, but it is not federally required.
What is the best vinyl for a trailer in New Hampshire?
Premium 6-mil cast vinyl with a UV laminate handles cold New England winters and road salt for 6 to 7 years. Standard calendared vinyl gives 3 to 4 years and is fine for short-term lettering.
Can I add my company name and number to a trailer myself?
Yes. Hoosier Decal ships pre-spaced vinyl lettering kits that any trailer owner can apply with masking tape and a squeegee. Watch our how-to-apply video before starting.
