If your vessel requires registration, it is illegal to operate it or allow others to operate your vessel unless it is registered and numbered as described below.

Montana Boat Validation and Registration Decals

The registration number, registration decal, and validation decals must be displayed as follows.

  • Number must be painted on or attached to each outboard side of the bow (forward half) of the vessel.
  • Number must read from left to right on both sides of the vessel.
  • Number must be in at least three-inch-high, vertical BLOCK letters.
  • Number's color must contrast sharply with its background.
  • Number must be as high above the water line as practical and still be visible.
  • Letters must be separated from the numbers by hyphens or spaces; for example: MT-234-ABC or MT 234 ABC.
  • The permanent registration decal must be securely attached to the left or port side of the vessel. The decal must be spaced three inches aft (rearward) and directly in line with the vessel number displayed on the left side of the vessel.
  • The two validation decals must be securely attached on each side of the vessel. One decal must be attached immediately aft (rearward of) the registration decal on the left (port) side and one immediately after the identifying number on the right (starboard) side of the vessel.
  • No numbers or letters may be displayed on the bow of the vessel.
