Where to search for boat registration information
Boat registration records are held by your state's Department of Motor Vehicles, Fish and Wildlife agency, or Parks and Recreation department — the exact agency depends on which state issued the registration. Most states let you search their records online for free, though some require you to visit in person or call. A few states charge a small fee to access registration details.
The fastest way to find the right agency is to start with your state's official website and search for "boat registration" or "vessel registration." From there, look for a link labeled "search records," "look up registration," or "vessel database." If your state does not offer online search, the agency's phone number will be listed on that same page.
You will need either the boat's hull identification number (HIN) or the registration number to search. The HIN is a unique 12-character code stamped on the boat's hull, usually near the transom or on the starboard side. The registration number is printed on your certificate of registration or on the boat's hull in the form of numbers and letters assigned by your state.

How to find your state's boat registration agency
Each state maintains its own boat registration system, so you must go to your state's official agency rather than a national database. Start by visiting your state's main government website and using the search function to look for "boat registration" or "vessel registration." This will direct you to the correct department.
In most states, boat registration is handled by the Department of Motor Vehicles (DMV), but some states place it under Fish and Wildlife, Parks and Recreation, or a separate Boating Safety division. The agency name varies, so do not assume it will be the same as in another state. Once you find the right page, look for a section labeled "search," "look up," "records," or "database."
If you are unsure which state issued the registration, check the boat's title document or the registration certificate itself — the issuing state will be printed on both. If you no longer have these documents, you can contact the state where the boat is currently moored or where it was last registered.
What information you need to search
Most state databases require one of two pieces of information: the hull identification number (HIN) or the state registration number. The HIN is a permanent identifier assigned by the boat's manufacturer and never changes, even if the boat is sold or re-registered. The registration number is assigned by your state and changes if you move to a different state or let your registration lapse.
The HIN is a 12-character code that looks like this: ABC1234D5678. It is stamped into the hull material itself, usually on the starboard (right) side of the boat near the transom, or sometimes on a removable plate. On smaller boats, it may be on the inside of the hull. If you cannot find it on the boat itself, check your title document, insurance policy, or previous registration certificate.
The registration number is easier to locate — it is printed on your current registration certificate and is usually also painted or stenciled on both sides of the boat's hull. If you have lost your registration certificate, you can request a replacement from your state's boat registration agency, though this may require a small fee.
Using an online boat registration database
Once you have found your state's registration search page, enter either the HIN or the registration number into the search box. Some databases allow you to search by owner name as well, though this is less common and may return multiple results if the name is common. After you enter the information and click search, the database will display the registration record if it exists in that state's system.
The information returned typically includes the registered owner's name, the boat's make and model, the registration number, the registration status (active, expired, or suspended), and the expiration date. Some states also show the hull identification number, the boat's length, and the date the registration was issued. However, most state databases do not display the owner's address, phone number, or email address for privacy reasons.
If the search returns no results, the boat may be registered in a different state, the registration may have expired and been removed from the active database, or you may have entered the HIN or registration number incorrectly. Double-check the number and try again, or contact the state agency directly to confirm whether the boat is registered there.
Searching by phone or in person
If your state does not offer an online search option, you can contact the boat registration agency by phone during business hours. Have the HIN or registration number ready when you call. The staff member will look up the record and provide you with the information over the phone. Some agencies will also email or mail you a copy of the registration record if you request it.
To search in person, visit your state's boat registration office or a local DMV branch that handles boat registrations. Bring the HIN or registration number with you, along with a photo ID. The staff will search the database and provide you with a printout of the registration record. This method is useful if you need an official certified copy of the registration for legal or insurance purposes.
Processing times vary by state. Phone searches are usually completed within a few minutes. In-person searches may take 15 to 30 minutes depending on how busy the office is. If you need an official certified copy, the office may require you to submit a written request and may charge a fee, typically between $5 and $25.
What to do if you cannot find the registration
If your search returns no results, the boat may not be registered in the state you searched, or the registration may be expired. Boats that are not actively used do not always need to be registered, depending on the state and the boat's size, so an unregistered boat is not necessarily illegal. However, if you are trying to locate a boat for a specific reason — such as a lien, a title transfer, or a legal matter — you may need to search multiple states.
If you know the boat was registered in a particular state but cannot find it, contact that state's boat registration agency directly and ask whether the registration has expired or been removed from the system. They can tell you when the registration was last active and may be able to provide historical records. Some states keep expired registrations in their database for a set number of years, while others purge them after a shorter period.
If you are searching for a boat to purchase and the seller cannot produce a registration certificate, ask the seller to contact their state's agency to request a replacement or to confirm the registration status. A legitimate seller should be willing to do this. If the seller refuses or cannot provide proof of registration, that is a red flag and you should reconsider the purchase.
Fees and access restrictions
Most states offer free online boat registration searches with no login required. However, some states restrict access to certain information or charge a fee for detailed records. A few states require you to create an account or provide a reason for your search before you can access the database.
If your state charges a fee, it is typically between $5 and $15 per search. Some states offer a lower fee for online searches and a higher fee for certified copies or in-person searches. A small number of states restrict registration searches to the registered owner, their authorized representative, or people with a legal reason to access the information, such as law enforcement or a court order.
If you encounter a paywall or access restriction, read the instructions carefully to see whether you may have access to for free access. Registered owners can usually search their own boat's record at no cost. If you are not the registered owner and the state restricts access, you may need to provide documentation of your legal interest in the boat, such as a lien, a court order, or a bill of sale.
Frequently Asked Questions
Can I search for a boat registration if I do not know the HIN or registration number?
Some state databases allow you to search by the owner's name or the boat's make and model, but this is less common. If your state's online search requires an HIN or registration number and you do not have one, contact the state agency by phone and explain what information you do have. Staff can often search by owner name or other details and provide you with the HIN or registration number.
How long does it take to get a search result?
Online searches return results when ready. Phone searches usually take a few minutes. In-person searches at a government office typically take 15 to 30 minutes. If you request a certified copy by mail, allow 5 to 10 business days for processing and delivery, depending on the state.
Will the search show me the boat owner's contact information?
Most state databases do not display the owner's address, phone number, or email for privacy reasons. The search result usually shows only the owner's name, the boat's details, and the registration status. If you need to contact the owner, you may need to hire a private investigator or attorney, or contact your state's boat registration agency to ask whether they can forward a message on your behalf.
What if the boat is registered in a different state than where it is currently located?
Boats are registered in the state where the owner lives or where the boat is primarily kept, not necessarily where it is currently docked. If you know the boat's previous state of registration, search that state's database first. If you do not know which state registered the boat, you may need to search multiple states or contact a marine title company that specializes in boat ownership records.
Can I search for a boat that is no longer registered?
Some states keep expired registration records in their database for several years, while others remove them after a shorter period. If the boat's registration has expired, you may still find it in the system, but the record will show an expired status. Contact your state's boat registration agency to ask how long they retain historical records and whether they can provide information about a boat that is no longer actively registered.
