Pennsylvania rules in detail
Minimum character height
Pennsylvania 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
Bold block letters and numbers, 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
Dash or space equal to the width of an ordinary letter or number. Example: PA 1234 AB. Running the groups together with no separation does not match the stated format.
Placement on the hull
Each side of the forward half. Must remain clearly visible.
Validation decal placement
Use the current Pennsylvania placement diagram issued with the registration. The validation or expiration decal is issued by Pennsylvania Fish and Boat Commission — RegistrationDecals.com supplies the registration-number lettering only.
Common mistakes
- Ordering the number without the PA 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 bold block letters and numbers.
- Losing the required separation between the groups — dash or space equal to the width of an ordinary letter or number.
- Placing the state validation decal somewhere other than the position Pennsylvania describes: use the current Pennsylvania placement diagram issued with the registration.
