Hull ID Number Corrections

The U.S. Coast Guard has mandated (33 C.F.R. § 181.25) that all registered vessels in the State of Tennessee provide a properly formatted Hull Identification Number (HIN) to TWRA.
The HIN is a 12 digit number generally located on the outside of the hull in the upper right corner of the boat’s transom.

A properly formatted HIN begins with 3 letters, followed by 5 characters (either number or letter), then one letter, then one number, and lastly, the last two digits of the year. EXAMPLE: ABC12345D313

Customers with an invalid HIN may renew their boats but only for the next three years. After the Coast Guard mandated deadline, our system will decline these renewals and any new owner applications.

It is imperative to correct these numbers in the system before that deadline.
