Tennessee boat registration is handled by the Tennessee Wildlife Resources Agency (TWRA), not your county clerk

Boats in Tennessee require registration through the TWRA, which is the state agency responsible for managing watercraft titles and registrations. This is separate from vehicle registration — you cannot register a boat at the same place you register a car. The TWRA issues a Certificate of Number (the boat's registration document) and a validation decal that must be displayed on the hull.

Registration is required for any motorized vessel, including boats with outboard motors, jet skis, and sailboats with auxiliary motors. Non-motorized boats like canoes and rowboats do not need registration. The registration process takes a few weeks if you explore by mail or in person, and you can renew online through the TWRA website.

Key Takeaways

  • The Tennessee Wildlife Resources Agency (TWRA) handles all boat registration, not county clerks or the DMV.
  • You need a bill of sale or title document, proof of ownership, and a completed process form to register a boat.
  • Registration costs vary based on boat length and whether you are registering a new boat or renewing an existing one.
  • The validation decal must be displayed on the hull and is valid for one year from the date of issue.
  • You can renew your boat registration online through the TWRA website if your contact information has not changed.

What documents you need to register a boat in Tennessee

Before you contact the TWRA, gather your proof of ownership. If you are registering a new boat, you will need either a bill of sale from the seller or a manufacturer's statement of origin (MSO) if the boat is brand new. If you are transferring a registration from another state, bring the out-of-state registration or title document.

You will also need to complete the process for Boat Registration form, which the TWRA provides on its website. The form asks for the boat's hull identification number (HIN), the motor serial number (if applicable), the boat's length, and your personal information. If someone else owns the boat with you, both owners must sign the process.

Bring a valid photo ID to prove your identity. If you are registering the boat under a business name or trust, you will need documentation showing that entity's legal name and your authority to register on its behalf.

How to register a boat in person or by mail

The TWRA has regional offices across Tennessee where you can register a boat in person. You can find the office nearest you on the TWRA website by searching for "boat registration" and your county. Bring all your documents, the completed process form, and payment. Registration is processed on the spot, and you will receive your Certificate of Number and validation decal when ready.

If you prefer to register by mail, send your completed process, proof of ownership, and payment to the TWRA's main office in Nashville. Include a copy of your photo ID. Processing by mail typically takes two to three weeks. The TWRA will mail your Certificate of Number and decal to the address you provide on the process.

Do not explore online for a new registration — the TWRA's online system is for renewals only. New registrations and transfers from out of state must be done in person or by mail.

Registration fees and how long your registration lasts

Boat registration fees in Tennessee are based on the boat's length. Boats under 16 feet cost less than boats 16 feet and longer. The TWRA website lists the current fee schedule, which changes periodically. You will also pay a one-time title fee if you are registering the boat for the first time in Tennessee.

Your registration is valid for one year from the date the TWRA issues it. The validation decal shows the expiration month and year and must be displayed on the hull where it is visible. When your registration expires, you can renew it online through the TWRA website if your address and ownership have not changed. If either has changed, you must renew in person or by mail.

Displaying your validation decal on the hull

The validation decal must be affixed to the hull on the starboard (right) side of the boat, near the stern (back). It should be placed where it is clearly visible and will not be covered by water or equipment during normal use. The decal is weather-resistant and designed to last the full year, but if it becomes damaged or unreadable, contact the TWRA for a replacement.

Operating a boat without a visible, valid decal is a violation and can result in a citation. Law enforcement officers check decals during routine waterway patrols, so make sure yours is current and properly displayed.

Renewing your boat registration online

If your boat registration is expiring and your ownership and address have not changed, you can renew online through the TWRA website. You will need your Certificate of Number and the last four digits of your Social Security number or tax ID. The online renewal takes a few minutes, and you can pay by credit card or debit card.

After you renew online, the TWRA will mail your new validation decal to the address on file. Remove the old decal from the hull and replace it with the new one before your registration expires. If you do not receive your new decal within two weeks of renewal, contact the TWRA to confirm your mailing address.

Transferring a boat registration from another state

If you are moving to Tennessee with a boat registered in another state, you must transfer the registration to Tennessee within 30 days of establishing residency. Bring your out-of-state registration or title, proof of Tennessee residency (such as a utility bill or lease), your photo ID, and a completed TWRA process form to a regional TWRA office or mail them to the main office.

You will pay Tennessee's registration fee and a title transfer fee. The TWRA will issue a new Tennessee Certificate of Number and validation decal. Some states allow you to keep an out-of-state registration if you are only visiting temporarily, but Tennessee requires registration for any boat kept in state waters for more than a few weeks.

Frequently Asked Questions

Do I need to register a canoe or kayak in Tennessee?

No. Non-motorized boats like canoes, kayaks, and rowboats do not require registration. If you add a motor to a non-motorized boat, you must then register it with the TWRA.

What happens if my boat registration expires?

Operating a boat with an expired registration is a violation. You can renew online if your information has not changed, or in person or by mail if it has. Renew before the expiration date shown on your decal to avoid a citation.

Can I register a boat I just bought without a title?

You need either a bill of sale from the seller or a manufacturer's statement of origin for a new boat. If the seller cannot provide a bill of sale, contact the TWRA to learn what other proof of ownership they will accept.

How do I replace a lost or damaged validation decal?

Contact the TWRA with your Certificate of Number and explain that your decal is lost or damaged. They will mail you a replacement decal at no charge. Do not operate the boat without a valid decal displayed on the hull.

Can I register a boat online if I just bought it?

No. New registrations and transfers from out of state must be done in person at a TWRA regional office or by mail. Online renewal is available only for boats already registered in Tennessee whose ownership and address have not changed.
