Michigan boat registration is handled by the Michigan Department of Natural Resources, not your local Secretary of State office

Boat registration in Michigan works differently from car registration. You do not go to your county clerk or Secretary of State. Instead, you register through the Michigan Department of Natural Resources (DNR), which issues a Certificate of Number — the boat equivalent of a license plate. This certificate is required before you can legally operate any motorized vessel on Michigan waters.

The process takes about two weeks if you submit everything correctly the first time. You can register in person at a DNR office, by mail, or online through the Michigan DNR website. The online option is fastest and available 24 hours a day.

Key Takeaways

  • Michigan requires a Certificate of Number from the DNR for any motorized boat, and you cannot legally operate without it.
  • You need proof of ownership (bill of sale, title, or manufacturer's certificate), proof of Michigan residency, and the boat's hull identification number (HIN) to register.
  • Registration costs between $25 and $100 depending on boat length and whether you choose a one-year or three-year certificate.
  • Online registration through the Michigan DNR website is the fastest method and takes about two weeks from submission to receiving your certificate.
  • Your Certificate of Number must be displayed on the boat's hull and renewed before it expires, or you face fines and cannot legally operate.

What documents you need to bring or submit

The DNR requires three categories of documents. First, proof of ownership: a bill of sale, manufacturer's certificate of origin, or existing title. If the boat is used, the seller should provide a bill of sale with both signatures and the date. If it is new, the manufacturer's certificate comes with the boat.

Second, proof of Michigan residency. A driver's license, utility bill, lease, or mortgage statement dated within the last 60 days works. If you are registering a boat at a business address, bring a business license or tax return showing that address.

Third, the hull identification number (HIN). This is a 12-character code stamped on the boat's hull, usually on the starboard (right) side near the waterline or on the transom (back). You will need to provide this number on the registration form. If the HIN is missing or illegible, you must have the boat inspected by a DNR officer before registration.

Registration costs and certificate length options

Michigan offers two registration periods: one year or three years. A one-year Certificate of Number costs $25 for boats under 26 feet and $40 for boats 26 feet and over. A three-year certificate costs $60 for boats under 26 feet and $100 for boats 26 feet and over. The three-year option saves money if you plan to keep the boat registered for that long.

These fees have not changed in recent years, but the DNR can adjust them. Check the Michigan DNR website before you register to confirm current pricing. Some counties or municipalities may charge additional fees for launching or mooring, but those are separate from the state registration fee.

How to register online, by mail, or in person

Online registration is the fastest route. Go to the Michigan DNR website, find the boat registration section, and fill out the form with your personal information, boat details, and HIN. You will pay by credit or debit card. The DNR will mail your Certificate of Number to the address you provide, usually within two weeks. You can print a temporary registration receipt to carry on the boat while you wait for the physical certificate.

Mail registration takes longer. read the boat registration form (Form 2915) from the Michigan DNR website, fill it out completely, and mail it with a check or money order and copies of your proof of ownership and residency to the DNR address listed on the form. Allow three to four weeks for processing and mailing.

In-person registration at a DNR office is an option if you want to hand over documents directly. Find your nearest DNR office on the Michigan DNR website. Bring originals of your proof of ownership and residency, your HIN, and a check or cash for the fee. You will receive a temporary receipt on the spot and the Certificate of Number by mail within two weeks.

Where to display your Certificate of Number

Once you receive your Certificate of Number, the DNR will assign you a registration number. You must display this number on both sides of the boat's hull, forward of the midship and above the waterline. The numbers must be at least 3 inches tall, in a contrasting color (usually black on white or white on black), and clearly visible. You can paint the numbers directly on the hull or use decals.

You must also carry the physical Certificate of Number on the boat whenever you operate it. A DNR officer can stop you and ask to see it. If you cannot produce it, you face a fine. Keep the certificate in a waterproof pouch or bag so it does not get damaged.

Renewing your certificate before it expires

Your Certificate of Number expires on the date printed on the certificate. You can renew it up to 90 days before the expiration date. The renewal process is the same as initial registration: online, by mail, or in person. If you renew online, you will receive the new certificate by mail within two weeks.

Do not let your certificate expire. Operating a boat without a valid Certificate of Number is illegal and can result in fines starting at $100. If your certificate expires and you want to register again, you will need to submit the full registration packet again, not just a renewal form.

Boats that do not need Michigan registration

Not all boats require a Certificate of Number. Non-motorized boats — canoes, kayaks, sailboats without motors, and rowboats — do not need to register. Boats registered in another state that are temporarily in Michigan (less than 60 consecutive days) do not need a Michigan certificate, but you should carry proof of registration from your home state.

Boats owned by the federal government, state government, or a municipality are exempt. Personal watercraft (jet skis) require registration but follow a slightly different process through the Secretary of State, not the DNR.

What happens if you lose or damage your certificate

If your Certificate of Number is lost, stolen, or damaged beyond readability, contact the Michigan DNR and request a duplicate. You will need to provide your boat's HIN and proof of ownership. The DNR will issue a replacement certificate, usually within one to two weeks. There is typically no additional fee for a duplicate.

If your registration number on the hull becomes faded or illegible, you must repaint or replace the decals. A DNR officer can cite you if the numbers are not visible. Repainting is inexpensive and can be done at any marine shop or by hand if you have steady hands and the right paint.

Frequently Asked Questions

Do I need to register a boat I just bought but have not launched yet?

Yes. You need a Certificate of Number before you can legally operate the boat on Michigan waters, even for the first time. Register it before launching. If you are transporting it overland to another state, you do not need Michigan registration, but once it enters Michigan water, it must be registered.

Can I register a boat if I do not have a Michigan driver's license?

You need proof of Michigan residency, not a driver's license specifically. A utility bill, lease, or mortgage statement dated within 60 days works. If you are a non-resident, you can still register a boat in Michigan, but you will need to provide an out-of-state address and may face different rules — contact the DNR directly to confirm.

What if the hull identification number is worn off or missing?

You cannot register the boat until the HIN is restored or verified. Contact the Michigan DNR to schedule an inspection. A DNR officer will examine the boat and either confirm the HIN or issue a new one. This process takes a few days to a week and may have a small fee.

How long does it take to get a Certificate of Number?

Online and in-person registration typically take two weeks from submission to delivery. Mail registration takes three to four weeks. If you register in person, you receive a temporary receipt when ready that you can use until the physical certificate arrives.

Can I transfer my boat registration to someone else?

No. When you sell the boat, the new owner must register it in their own name. Provide the buyer with a bill of sale and your proof of ownership. The buyer then submits their own registration packet to the DNR with their proof of residency and ownership documents.
