New Mexico rules in detail
Minimum character height
New Mexico specifies characters 3 inches high. Measure the character body itself — if the state excludes borders, outlines or shading, decorative trim does not count toward the minimum.
Required lettering style
Block / legible characters, reading left to right. Script, italic and decorative treatments are not what this style describes.
Contrast requirement
Contrasting color. In practice that means dark characters on a light hull and light characters on a dark hull, checked in daylight from the side of the vessel.
Spacing and separator
Space or hyphen. Example: NM 1234 AB. Running the groups together with no separation does not match the stated format.
Placement on the hull
Each side of the motorboat's forward half. Assigned registration only.
Validation decal placement
Follow the current New Mexico registration instructions. The validation or expiration decal is issued by New Mexico State Parks Division — RegistrationDecals.com supplies the registration-number lettering only.
Common mistakes
- Ordering the number without the NM prefix or the suffix letters.
- Characters shorter than the stated minimum (3 inches) so they fit inside a narrow accent stripe.
- Using a script, italic or shadowed style instead of block / legible characters.
- Losing the required separation between the groups — space or hyphen.
- Placing the state validation decal somewhere other than the position New Mexico describes: follow the current New Mexico registration instructions.
