Troubleshooting & FAQ
Do these numbers meet U.S. Coast Guard regulations?
Yes, the 3-inch block lettering meets USCG requirements for vessel identification numbers when you choose a color that contrasts with your boat's hull.
How many of each letter and number are included?
The package contains four full sets of letters A-Z and four full sets of numbers 0-9, ensuring you have enough to create any registration ID, with spares.
What is the best way to ensure the numbers are applied straight?
For best results, use a measuring tape and a straight edge (like a ruler) to create a light pencil or masking tape guideline on the hull before application. This helps keep your letters and numbers perfectly aligned.
Can these stickers be removed?
These decals are made with strong adhesive for marine environments. While they can be removed, it may require gentle heat from a hairdryer and a plastic scraper or adhesive remover to avoid damaging the underlying surface.
What type of surface is best for application?
A clean, smooth, non-porous surface like gelcoat, fiberglass, or painted aluminum is ideal. Avoid applying over heavy textures, wax, or oil, as it will compromise adhesion.
How should I space the characters?
USCG regulations require a space or hyphen equivalent to the width of one letter (except for the first and last characters) between the letter and number groups. Example: CF 1234 AB or CF-1234-AB.
