Florida Boat Registration Numbers: Size, Placement and Decal
Florida boats carry an FL number on both sides of the bow and a validation decal on the port side. Here is what the statute says and where owners slip up.
In Florida, a numbered boat carries its FL registration number on both sides of the bow and a validation decal on the port side. The details are in Florida Statute 328.48. This page summarizes them in plain words. It is not legal advice, and you should confirm with the Florida Fish and Wildlife Conservation Commission or your county tax collector before you apply anything.
The number
- It goes on each side of the forward half of the vessel.
- The characters are block letters at least 3 inches tall, read from left to right, in a solid color that contrasts with the hull.
- The federal rule behind it (33 CFR 173.27) also asks for a space or hyphen between the letter and number groups, as wide as a letter.
The validation decal
- It goes on the port (left) side only, within 6 inches before or after the number.
- A previous year's decal has to be removed.
- For a documented vessel, the decal goes on the port side or on a port-side window or windshield.
Common slips
- Putting the decal on both sides. Florida asks for the port side only.
- Placing it farther than 6 inches from the number.
- Leaving the old decal on.
- Letters just under 3 inches, or in a script style.
Ordering the number
Our boat registration number decals are made from the number you type, in block letters from 3 to 5 inches tall. You see the decal at true size before you buy. Order two, one for each side. We make the lettering only: the validation decal comes from the state.

Frequently asked questions
How big do Florida boat numbers have to be?
At least 3 inches tall, in block letters, according to Florida Statute 328.48. The federal rule (33 CFR 173.27) says the same for the characters and adds that they must be plain, vertical and contrasting.
Where does the Florida decal go?
On the port (left) side of the boat, within 6 inches before or after the registration number. It goes on the port side only, not on both sides.
Do I need to remove last year's decal?
Yes. Florida's statute asks for a previous year's decal to be removed so the current one is the only one displayed.
What if my boat is documented?
A documented vessel carries its name and hailing port in letters at least 4 inches tall under the Coast Guard rule (46 CFR 67.123). In Florida the validation decal then goes on the port side or on a port-side window or windshield. Check the agency page for the exact case.
Does the FL prefix go before the numbers?
Your registration number is the group your state issued, such as FL 1234 AB. Type it exactly as issued, with the same spaces or hyphens, and keep the groups separated.
Where on the hull does the number go?
On each side of the forward half of the boat. If the number would not be easily visible on the hull or superstructure, the federal rule allows a backing plate attached to the forward half, visible from each side.
Can I make my own number letters?
Yes, as long as they are plain block characters 3 inches or taller in a contrasting color. Vinyl decals are a common way to do it. Our page shows the decal at true size before you buy.
- Have the number exactly as Florida issued it, with its spaces or hyphens.
- Measure the forward half of each side and confirm the letters fit at 3 inches or taller.
- Pick a contrasting solid color: black on a light hull, white on a dark hull.
- Plan the decal spot on the port side, within 6 inches of the number, before you stick the number down.
- Remove last year's decal and any old numbers that could be confused with the new ones.
- Step back and look at both sides from the dock before pressing the letters down firmly.
Florida also asks that the registration certificate be on board when the boat is in use. The agency page lists what else to carry. If you buy a boat that already has lettering, check that the number matches the paperwork before you rely on it.
