Product Details

These 3-inch black boat registration numbers and letters decals provide a practical DIY solution for displaying registration identification on boats, personal watercraft, and jet skis. Made from UV-coated vinyl with self-adhesive backing, the decals are designed for application to clean, smooth surfaces commonly found on marine vessels.

  • Easy DIY Installation: Peel and apply the self-adhesive characters to a properly prepared, smooth surface.
  • Marine-Ready Material: UV-coated vinyl helps the decals withstand outdoor exposure and everyday marine use.
  • Complete Character Sets: The package includes four complete sets of A–Z letters and four complete sets of 0–9 numbers for assembling registration codes.
  • Black Characters: The black finish provides a clear, contrasting appearance on suitably colored hull surfaces.

  3. Use a pencil, measuring tool, or masking tape to mark a straight guideline for alignment.

  5. Apply each character carefully, pressing from the center outward to help avoid wrinkles or air pockets.
  6. Press the decals firmly onto the surface and allow the adhesive to set according to the material and environmental conditions.

Troubleshooting & FAQ

What do I get in one package?

The package contains four full sets of A–Z letters, for 104 total letters, and four full sets of 0–9 numbers, for 40 total numbers. This provides extra characters for assembling registration codes or replacing individual decals.

Are these decals compliant with boating regulations?

Character-height and placement requirements can vary by jurisdiction and vessel type. These decals are 3 inches tall, but you should verify the applicable local requirements for character size, contrast, spacing, and placement before installation.

How do I ensure the numbers are straight?

Use a measuring tool or strip of masking tape to create a straight guideline before applying the characters. Plan the complete sequence first so the spacing remains even across the available surface.

What surfaces can I apply these to?

These decals are intended for clean, smooth, non-porous surfaces such as painted fiberglass, metal, plastic, and glass. Test an inconspicuous area if you are unsure how the adhesive will interact with a particular finish.

Are these OEM decals?

This listing is for aftermarket registration decals. They are intended for general marine registration-display applications and are not identified as an OEM-branded component.

How should I prepare the surface?

Remove dirt, oil, wax, and other contaminants from the application area, then allow the surface to dry completely. Applying decals to a clean, dry, smooth surface helps support proper adhesion.

Safety & Important Information

  • Check the character size, color contrast, spacing, and placement requirements that apply to your vessel and location before installation.
  • Do not apply decals to dirty, wet, heavily textured, loose, or peeling surfaces.
  • Confirm the layout before removing the backing, because adhesive decals may be difficult to reposition after application.
  • This is an aftermarket decal set, not an OEM-branded component.
