Hull Identification Number (HIN)

Every boat carries a kind of fingerprint: a string of characters stamped into the hull that tells you who built it, where, and when. That’s the Hull Identification Number, and if you own a boat in Canada, it matters more than most realize. It’s what your insurer asks for, what police use to trace a stolen vessel, and what Transport Canada relies on when a recall goes out. Here’s what every Canadian boater should understand about it.

 

Key Takeaways

• The HIN and your Pleasure Craft Licence are not the same. The HIN identifies the hull and never changes; the Pleasure Craft Licence is tied to the boat’s operation and displayed on the bow.
• The HIN is on the transom. Look at the upper starboard (right) corner where it stays visible when the boat is in the water.
• Inflatable boats need a HIN too. In the eyes of Transport Canada, an SIB or RIB is a boat. Many also need a Pleasure Craft Licence once the motor reaches 10 HP.
• The 12 characters in the HIN each have a meaning. The manufacturer code, hull serial number, build date, and model year all tell you something about the boat.
• It is illegal to tamper with a HIN. Changing, damaging, or removing it can make it impossible to sell or register your boat, and it quickly causes suspicion.

 

What Is a HIN?

A Hull Identification Number is a unique 12-character code assigned to a single boat. Think of it as the marine equivalent of a car’s VIN. It identifies one specific hull and nothing else, which is why it’s so useful for registration, insurance claims, and recovering stolen vessels.

In Canada, the HIN became mandatory on August 1, 1981. Any pleasure craft built or imported after that date must carry one. Boats built before then often won’t have a HIN — something to know if you’re shopping for an older vessel.

 

Why Your Boat Needs a HIN

The HIN does a lot of quiet work behind the scenes. It helps Transport Canada and manufacturers track boats affected by safety recalls. It helps police confirm ownership when a vessel is recovered after being reported stolen. And it’s the number your insurer wants on file.

It’s separate from your Pleasure Craft Licence number, and people mix these up constantly. The licence number is painted on the bow. The HIN is permanently affixed to the hull and stays with the boat for life, even through multiple owners. Every boat sold through Navigator carries its original, unaltered HIN, so it’s traceable and verifiable from the day you take it home.

 

Do Inflatable Boats Need a HIN?

Yes. There’s a common assumption that inflatables sit outside the rules — they don’t. Any inflatable boat built or imported into Canada needs a HIN, just like a fibreglass runabout or an aluminium fishing boat.

Whether you need a Pleasure Craft Licence depends on the motor. Once your inflatable is powered by engines totalling 10 HP (7.5 kW) or more, a licence is required by law. Provincial rules can add their own requirements, so check with your provincial boating authority before launch day. We cover the full licensing side in our guide.

 

What’s a Pleasure Craft Licence Number?

A Pleasure Craft Licence number is a unique identifier issued by Transport Canada for recreational boats powered by motors totalling 10 HP (7.5 kW) or more. It has to be displayed on both sides of the bow, above the waterline, in block characters at least 7.5 cm (3 inches) high and in a colour that contrasts with the hull. The licence itself is free, valid for 10 years, and exists so that search and rescue or law enforcement can quickly identify your boat on the water.

 

Where to Find the HIN on Your Boat

Under Canada’s Small Vessel Regulations, the main HIN is permanently marked on the outside upper starboard quarter of the transom, the back right corner, within reach of the top edge. It must stay visible while the boat is in the water. Every character must be at least 6 mm (¼ inch) tall.

If your boat has no transom, the HIN goes on the starboard side near the stern. On a dinghy, look aft on the starboard outboard side, within about a foot of the back.

 

Breaking Down the 12 Characters

The HIN isn’t a random string. Every section carries information, and once you can read it, you can tell a lot about a boat at a glance.

• Manufacturer Identification Code (first 3 characters). Issued by Transport Canada, this identifies who built or imported the boat.
• Hull serial number (next 5 characters). Assigned by the manufacturer, the boat’s individual number within that builder’s production.
• Build Date (2 characters). A letter for the month construction began, followed by a digit for the year. Months run A through L, January through December.
• Model year (last 2 characters). The year the boat was marketed.

For boats built outside Canada or the United States, a two-character country code is added to the front, separated by a dash — for example, AU- for an Australian-built hull. Canada recognizes US manufacturer codes directly, so American-built boats don’t need the extra prefix.

Month code	Month	Month code	Month
A	January	G	July
B	February	H	August
C	March	I	September
D	April	J	October
E	May	K	November
F	June	L	December

 

The Second, Hidden HIN

Here’s a detail many owners never notice: your boat should carry the HIN in two places. Alongside the visible transom marking, there’s a duplicate in a concealed spot — inside the hull, under a fitting, or beneath a piece of hardware. If the main HIN is ever damaged or tampered with, that hidden copy still confirms the boat’s identity. It’s a quiet but effective theft deterrent.

 

How to Get a HIN in Canada

If you’re a manufacturer or importer, the process starts with Transport Canada. You apply for a Manufacturer Identification Code by submitting a Request for a Manufacturer Identification Code form to the Small Vessel Manufacturers and Importers Compliance Program. That three-character code becomes the front of every HIN you assign. Transport Canada usually processes a complete request within about 15 business days. The full procedure is laid out on the Transport Canada hull serial number page.

If you’ve bought a boat without an HIN, you’re responsible for getting one. Contact the original manufacturer, rebuilder, or importer and request that a number be assigned and inscribed. Don’t skip this — a boat without a HIN is difficult to insure, register, or resell.

 

Looking Up a HIN

Buying used? The HIN is your best tool for checking a boat’s history before you hand over money. The Canadian Police Information Centre runs a public stolen-vessel search that lets you enter a HIN, licence number, or registration number to see whether the boat has been flagged. It takes two minutes and can save you a serious headache.

 

Building Your Own Boat

If you build a boat for your own personal use rather than for sale, you fall outside the manufacturer compliance process — no Declaration of Conformity, no Compliance Notice. Your boat still needs a HIN, though. The route is to contact Transport Canada’s Office of Boating Safety to arrange one before you put the boat in the water. The same rule applies as for any other vessel: a homebuilt boat without a HIN is a problem waiting to happen at registration or resale.

 

What’s Next?

A HIN handles identification. Licensing and registration are the other half of being road-legal — or rather, water-legal — in Canada, and they trip up plenty of new owners. We cover exactly which boats need a Pleasure Craft Licence, when registration makes sense instead, and how to apply for both in our guide to licensing and registering your inflatable boat.
