Where can I find a vessel’s USCG documentation number?

You can find a vessel’s USCG documentation number by conducting a search at our site. You can start with the form Foreign vessel title search request/transcript of registry or simply type in the vessel’s Official Number or HIN. Then, you’ll be provided with information about the vessel such as its documentation number, dimensions, particulars, tonnage information, the date its certificate of documentation was issued as well as the date it expires, and more.

On the Certificate of Documentation itself, you can find the documentation number in the top-center of the form.
