New York Boat Registration Number Rules
Registering a boat in New York means putting your assigned number on the hull — in a specific size, a specific style, and a specific place. Here is what the rules actually say, plus where your validation decal belongs.
Your registration number goes on both sides of the forward half of the hull, in plain vertical block characters at least 3 inches tall, in a color that contrasts with the hull, reading left to right — like NY 1234 AB.
Where your New York validation decal goes
Registration stickers 18 in from the bow on both sides (NY DMV); legibility at 100 ft per NY guidance.
This is the detail most people get wrong, and it is state-specific — the sticker position is set by New York, not by the federal rule. Leave room for it when you place your numbers, because moving cut vinyl after it is applied is not realistic.

The federal standard (33 CFR 173.27)
Registration number: plain vertical BLOCK characters not less than 3 inches high; contrasting with background, distinctly visible and legible; read left to right; painted on or permanently attached to each side of the forward half of the vessel; spaces or hyphens equal to a letter width between letter and number groupings (e.g., FL 1234 AB or FL-1234-AB). Validation sticker placement is set by each state, not 173.27.
Need your numbers?
Type your registration number, add your boat name, choose colors and size, and see it before you buy. Sold single or in pairs for both sides.
Getting the look right
- Block letters only for the registration number — plain, vertical, no script and no outline-only styles.
- Contrast matters — white numbers vanish on a white hull. Black, red or navy read well on light gel coat; white or yellow work on dark hulls.
- Mind the curve — the bow flares, so measure where the numbers will actually sit, not where the hull is flat.
- Marine-grade vinyl — ours is cast 7-year film, which handles sun, trailer speed and washdowns without cracking.
Boat names are a different story
Your registration number has rules. Your boat name does not — it is pure personality, and it is the part people photograph. We cut names in script faces like Pacifico and Lobster as well as block styles, at whatever size suits the transom, and you can design the name and the numbers in the same session.
Common questions
How big do boat registration numbers have to be in New York?
At least 3 inches tall, in plain vertical block letters that contrast with the hull color. Script and outline-only fonts are not acceptable for the registration number itself.
Where exactly do the numbers go?
On both sides of the forward half of the vessel — normally the bow — high enough above the waterline to stay visible, reading left to right.
Do I need spaces or hyphens in the number?
Yes. The letter and number groups have to be separated by a space or hyphen about as wide as a letter, so NY 1234 AB or NY-1234-AB. Our designer spaces this correctly for you.
Can I put my boat's name on too?
Absolutely, and it is not regulated the way the registration number is — so script fonts, bigger sizes and any color are fair game. Most people run the name on the transom or along the hull side and keep the registration number in block letters on the bow.
