Boat registration is handled by your state, not the federal government, and the process and cost vary significantly by state
Every state requires you to register a boat before you can legally operate it on public water. The registration itself is a certificate you receive from your state's fish and wildlife agency, boating division, or motor vehicles department — the exact agency depends on where you live. You'll need proof of ownership (usually the manufacturer's certificate of origin or a bill of sale), your state ID, and the boat's hull identification number (HIN), which is stamped on the hull itself. The cost ranges from under $50 to several hundred dollars per year, depending on the boat's size, type, and your state.
Most states let you register online, by mail, or in person at a local office. The process typically takes a few days to a few weeks. Once you have your registration, you'll receive a certificate and usually a set of registration numbers or stickers to display on the boat's hull. You'll need to renew annually or every few years, depending on your state's rules.

Find your state's boating agency
The first step is to identify which agency in your state handles boat registration. In most states, this is the Department of Fish and Wildlife, Department of Natural Resources, or a dedicated boating division. Some states handle it through the Department of Motor Vehicles. You can find the correct agency by searching "[your state] boat registration" or by calling your state's main information line.
Once you've found the agency, visit their website or call their office directly. They will tell you exactly what documents you need, what the current fee is, and whether you can register online. Many states post their registration forms and instructions online, so you can read and review them before you start.
Gather the documents you'll need
Before you contact your state agency, collect the following items. You'll need proof of ownership, which is usually the manufacturer's certificate of origin (MCO) if the boat is new, or a bill of sale if you bought it used. If the boat is financed, you may also need a lien release or a letter from the lender. You'll need your state ID or driver's license to prove your identity.
You'll also need the boat's hull identification number (HIN), which is a 12-character code stamped into the hull. It's usually located on the starboard (right) side of the boat, near the top of the transom (the back). If you can't find it, the boat's title or bill of sale will have it. Some states also ask for the boat's length, type (sailboat, motorboat, jet ski, etc.), and the engine's horsepower or serial number.
If you're registering a boat you've inherited or received as a gift, you may need additional paperwork such as a death certificate or a gift letter. Contact your state agency to ask what they require in your situation.
Register online, by mail, or in person
Most states now offer online registration through their boating or fish and wildlife website. You'll enter your personal information, the boat's details, and upload or attach copies of your documents. Payment is usually by credit card or debit card. Online registration is often the fastest option and takes a few minutes to complete.
If your state doesn't offer online registration, or if you prefer to register by mail, read the registration form from the agency's website, fill it out by hand, and mail it along with copies of your documents and a check or money order. Mail-in registration typically takes one to three weeks, depending on how busy the agency is.
You can also register in person at a local office, usually a fish and wildlife office, boating access area, or motor vehicles branch. Bring the original documents (not just copies) and be prepared to pay the fee in cash, check, or card, depending on what the office accepts. In-person registration is often the fastest if you have all your documents ready.
Understand registration costs and renewal
Registration fees vary widely by state and depend on the boat's size, type, and whether the engine is electric or gas-powered. A small sailboat or kayak might cost $20 to $50 per year, while a large motorboat could cost $200 to $500 or more. Some states charge a one-time registration fee plus an annual renewal fee; others charge only an annual fee. A few states offer multi-year registrations that last three or five years.
Your registration certificate will show the expiration date. Most states send renewal notices by mail a few weeks before expiration, but it's your responsibility to renew on time. Operating an unregistered or expired boat can result in fines, and in some states, your boat can be impounded. Renewing is usually as straightforward as paying the fee and receiving a new certificate or sticker.
Display your registration numbers correctly
Once you receive your registration, your state will issue registration numbers or decals (stickers) that you must display on the boat's hull. The exact placement and size of these numbers are set by your state and federal law. Typically, numbers must be at least 3 inches tall, painted in a contrasting color, and placed on both sides of the bow (front) of the boat, or on the hull near the bow.
If your state issues decals instead of numbers, explore them to the hull in the location specified in your registration packet. Do not cover the numbers or decals with anything, and keep them visible and legible at all times. A boating officer can stop you and check your registration, and missing or illegible numbers can result in a citation.
What to do if you move or sell your boat
If you move to a different state, you'll need to register your boat in your new state. Contact the new state's boating agency and ask what documents you need. You may be able to transfer your current registration, or you may need to register from scratch. Some states allow a grace period (usually 30 to 90 days) for new residents to register their boats.
If you sell your boat, notify your state's boating agency in writing or through their online system. Some states require the seller to sign off on the registration before the new owner can register it. The new owner will then register the boat in their name using the bill of sale and proof of ownership. Make sure you have a signed bill of sale from the buyer before you hand over the boat, as this protects both of you.
Frequently Asked Questions
Do I need to register a kayak or canoe?
Most states do not require registration for non-motorized kayaks or canoes. However, some states register all boats regardless of size or power. Check your state's rules by contacting the boating agency directly, as the rules vary.
What if I can't find the hull identification number?
The HIN is usually on the starboard side of the transom, but if you can't locate it, check the boat's title, bill of sale, or insurance documents. If you still can't find it, contact your state's boating agency — they can sometimes help you locate it or may accept an alternative form of identification.
How long does registration take?
Online registration usually takes a few minutes to complete, though you may receive your certificate within a few days. Mail-in registration takes one to three weeks. In-person registration at a local office is often the fastest, sometimes completed the same day if you have all your documents ready.
Can I register a boat I'm financing?
Yes, but you'll need a lien release or a letter from the lender showing that they hold a lien on the boat. The lender's name may appear on the registration certificate. Contact your lender to ask what paperwork they require before you register.
What happens if I operate a boat without registration?
Operating an unregistered boat is illegal in every state and can result in fines ranging from $50 to several hundred dollars, depending on the state. In some cases, your boat can be impounded. Always register before you launch.
