Louisiana boat registration is handled by the Louisiana Department of Wildlife and Fisheries, and the process depends on whether your boat is motorized, where you keep it, and whether you own it outright or are financing it.

Most boats used in Louisiana waters need a registration number and decal, even if they are trailered and only launched occasionally. The state issues a Certificate of Number (the registration document) and an annual validation decal that you display on the hull. The cost and timeline vary based on boat type and how long you want the registration to last.

You can register through the Wildlife and Fisheries website, by mail, or in person at a regional office. The fastest route is usually online if you have all required documents ready — typically proof of ownership, your driver's license, and proof of liability insurance if the boat is motorized.

Key Takeaways

  • Louisiana requires registration for most motorized boats and many non-motorized boats used in state waters, issued by the Department of Wildlife and Fisheries.
  • You will need proof of ownership (bill of sale, title, or manufacturer's certificate), a valid ID, and proof of liability insurance for motorized vessels.
  • Online registration through the Wildlife and Fisheries website is the fastest method and takes a few business days once documents are submitted.
  • Registration is valid for one, two, or three years depending on which option you choose at the time of registration.
  • The annual validation decal must be displayed on the hull; failure to display it can result in a citation from a wildlife officer.

Who needs to register a boat in Louisiana

Any boat with a motor — whether inboard, outboard, or jet drive — must be registered if it operates in Louisiana waters. This includes boats you own, boats you are financing, and boats you operate regularly even if someone else owns them.

Non-motorized boats (canoes, kayaks, sailboats without motors, rowboats) do not require registration unless they are rented to the public or used commercially. If you own a sailboat with an auxiliary motor, the motor triggers the registration requirement.

Boats registered in another state but used temporarily in Louisiana (generally fewer than 90 days per year) do not need Louisiana registration, but you should carry proof of your home state registration and liability insurance.

Documents you will need to register

Start by gathering proof of ownership. This is usually a bill of sale, a manufacturer's certificate of origin (for new boats), or a title document from your state. If you are financing the boat, the lender's name will appear on the title; you can still register it, but the lender has a security interest that the state records.

You will also need a valid government-issued ID (driver's license, passport, or military ID) and your Social Security number. For motorized boats, Louisiana requires proof of liability insurance — the insurer's name, policy number, and coverage dates. You do not need to submit the insurance document itself, just the information, though having it on hand when you register makes the process faster.

If you are registering on behalf of a business or trust, bring documentation showing your authority to act (corporate resolution, trust document, or power of attorney). If the boat is titled to multiple owners, all owners should be present or provide written consent.

How to register online, by mail, or in person

Online registration through the Louisiana Department of Wildlife and Fisheries website is the most direct route. You enter your boat information (hull identification number, length, motor type), upload photos of your proof of ownership and ID, and provide insurance details. The state processes online applications within a few business days and mails your Certificate of Number and decal to the address you provide. You can begin using the boat once you receive confirmation of registration, though you must display the decal once it arrives.

Mail registration requires you to complete the process form (available on the Wildlife and Fisheries website), include copies of your proof of ownership and ID, and mail everything to the address listed on the form. Processing takes two to three weeks from the date the office receives your packet. Include a check or money order for the registration fee; the state does not accept credit cards by mail.

In-person registration at a Wildlife and Fisheries regional office is the fastest if you need registration the same day. Bring originals of your proof of ownership, ID, and insurance information. The office staff will verify your documents, collect payment, and issue your Certificate of Number on the spot. The decal is mailed separately and usually arrives within a week. Regional offices are located in Baton Rouge, New Orleans, Lafayette, and other cities; check the Wildlife and Fisheries website for hours and locations.

Registration fees and how long registration lasts

Louisiana registration fees depend on the boat's length and the registration term you choose. Boats under 16 feet cost less than boats 16 to 26 feet, which cost less than larger vessels. The state does not publish a single fee schedule online because rates are set by statute and can change; the Wildlife and Fisheries website displays current fees when you start an online registration, or you can call a regional office to ask.

You can register for one year, two years, or three years. A longer term costs more upfront but spreads the cost across more years. Your validation decal shows the expiration year; you must renew before that date or you cannot legally operate the boat in Louisiana waters.

If you register a boat that is financed, the registration fee is the same. The lender's interest is noted on your Certificate of Number but does not change the cost or process.

What to do after you receive your registration

Once the Certificate of Number arrives, keep it on board or with your boat documentation. You are not required to carry it with you every time you operate the boat, but a wildlife officer can ask to see it, and having it available prevents delays or citations.

When the validation decal arrives, affix it to the hull on the starboard (right) side, forward of the registration number. The decal must be clearly visible and not obscured by dirt, damage, or other objects. A missing or illegible decal can result in a citation even if your registration is current.

Set a reminder for the month before your registration expires so you have time to renew. You can renew online, by mail, or in person using the same process as initial registration. If you sell the boat, notify the Wildlife and Fisheries office in writing so the registration is transferred to the new owner.

Registering a boat you are financing

If you are buying a boat with a loan, the lender will typically require proof of registration and liability insurance before releasing funds. You can register the boat before the loan closes — use the bill of sale or purchase agreement as proof of ownership, along with your ID and insurance information. Once the registration is complete, provide the Certificate of Number to your lender.

When the title is issued after the loan closes, the lender's name appears as a lienholder. You do not need to re-register; the existing registration remains valid. If you pay off the loan, ask the lender to send you a release of lien, which you can then use to remove their name from the title if you wish (this is optional and does not affect registration).

Frequently Asked Questions

Do I need insurance to register a boat in Louisiana?

Liability insurance is required for motorized boats at the time of registration. You must provide the insurer's name, policy number, and coverage dates. Non-motorized boats do not require insurance to register, but many marinas and boat ramps require proof of insurance anyway.

What is the hull identification number and where do I find it?

The hull identification number (HIN) is a unique 12-character code assigned by the manufacturer. It is usually located on the starboard side of the hull near the top edge, or on the transom (back of the boat). Check your bill of sale or manufacturer's paperwork if you cannot locate it on the boat itself.

Can I register a boat if I do not have a title?

If the boat is old or was built before titles were required, you may not have a formal title document. In that case, bring a bill of sale, a manufacturer's certificate of origin, or a notarized statement of ownership. Contact a Wildlife and Fisheries regional office before you register to confirm what documents they will accept for your specific boat.

What happens if my registration expires?

Operating a boat with an expired registration is illegal in Louisiana. A wildlife officer can cite you and may impound the boat. Renew before the expiration date shown on your decal. If your registration has already expired, you can still renew online or in person; the new term begins from the date you renew, not from the old expiration date.

Do I need to register a boat I am only using for a few weeks?

If you are visiting Louisiana from another state and plan to use your boat for fewer than 90 days per year, you do not need Louisiana registration. Carry your home state registration and proof of liability insurance. If you plan to use the boat more than 90 days in a year, register it in Louisiana.
