TowGauge

VIN LOOKUP · VEHICLE IDENTITY

Start with the VIN. Type less after.

TowGauge decodes the vehicle identity, checks whether that year/make/model exists in our live Canadian towing database, then carries the match straight into the calculator.

VEHICLE LOOKUP

Decode a 17-character VIN

0/17 characters · VINs exclude I, O and Q.

TowGauge does not save this VIN to a database. It is sent in the request body to the TowGauge decoder endpoint, then forwarded to NHTSA's vPIC service for the lookup. The decoded identity is compared with TowGauge's own live vehicle records.

WHAT HAPPENS AFTER THE VIN

Decode identity. Match the database. Resolve only the gaps.

The user should never have to enter the same information twice—or be given a towing number we cannot source.

01

Decode vehicle identity

Year, make, model, body, engine and drivetrain are populated where the manufacturer's VIN submission supports them.

02

Check the live TowGauge registry

The decoded year/make/model is matched against source-backed Canadian towing records before a calculator result is offered.

03

Ask only for what's missing

Engine, axle, tow package or payload are requested only when those details still change the applicable manufacturer rating.

What a VIN can—and cannot—confirm for towing

A VIN is useful for narrowing vehicle identity, but it is not automatically an exact towing-capacity certificate. Depending on the manufacturer and model year, the decoded data may not expose the axle ratio, cab and box combination, factory towing package or other equipment that changes the applicable trailer rating. TowGauge uses the VIN to reduce manual entry, then matches only against configurations that are already supported by source-backed Canadian towing data.

Payload and combination weight remain vehicle-specific too. The carrying-capacity label on the actual vehicle accounts for its installed equipment, while a GCWR check needs the vehicle's real loaded weight rather than factory curb weight. That is why TowGauge can identify a truck successfully and still leave one or more checks incomplete. Before towing, compare the matched configuration with the vehicle labels, hitch ratings and the manufacturer's towing guide.

About the VIN source

NHTSA says vPIC is populated from manufacturer submissions. Its dataset primarily represents vehicles intended for U.S. sale or import, so some Canadian-market vehicles may return limited information. TowGauge therefore treats vPIC as an identity layer—not the Canadian towing-rating authority. NHTSA vPIC
