What Is The USCG Documentation Number?

The USCG documentation number is the official number (ON) of a documented vessel. It stays with the boat for its lifetime. In some states, they allow state registration and federal documentation. Other states, however, do not let vessels to be identified as both a state registered and federally documented. However, if you live in a state that only allows either state registration or federal documentation, you still need to pay sales tax. And you must display the state validation sticker as a proof on your boat according to the state’s regulations.

How to place the USCG documentation number?

It must be permanently attached to your vessel. But, unlike state registration number, the ON of federal documentation is affixed to the interior part of the ship. But it has to be in a clearly visible area.  Apart from the official number, you also need to include the name of your vessel. The name may consist of letters of the Latin and Arabic alphabets or Roman numerals. It must not exceed 33 characters. Before you use your documented vessel for international cruising, make sure that the USCG documentation number has already been attached permanently to your vessel according to the requirements of the USCG. To display the number in the interior part of the vessel, you must mark the NO first before the designated number. The number has to be printed in Arabic numerals and capital letters. Furthermore, it has to be at least three inches in height.

USCG documentation

The USCG requires that the ON must be attached to the ship permanently. You must affix it in a way that when altering it, the change would be obvious or it would damage the hull area. You can use any material to market your boat. If you opt to order it online, you must specify that the marking will be used to meet the USCG documentation requirements. No matter what method you use to market the ON and name of the vessel, you must make sure that they are marked in a presentable way. If you wish to change the name of the vessel, you could apply for it. Once approved, you need to change the marketing on your boat to reflect the new name. If you failed to follow it, then you might be penalized. On the other hand, if you have not documented your vessel but wish to do so, you can apply for initial documentation using our service.
