California Boat Number Display Laws

California boat registration numbers must be displayed correctly on your vessel so they are easy to read and properly spaced. Use the guide below, then design your boat number decals below.

California Display Requirements

California requires registration numbers to be shown on both sides of the forward half of the boat. The numbers must be clearly visible, read from left to right, and use plain block characters at least 3 inches high. Registration stickers should be placed 3 inches aft of, and in line with, the registration numbers. :contentReference[oaicite:1]{index=1}
