Vehicle identification numbers were first used in 1954. From 1954 through 1981 there was no regulation of VIN numbers, and different manufacturers used differing formats. In 1981 the National Highway Traffic Safety Administration standardized the format into a unique 17-digit number that did not include the letters I, O or Q. These letters were avoided to eliminate confusion with the numbers one and zero. All vehicle identification numbers still use a related 17-digit format which conforms to standards set by the International Organization for Standardization, known as ISO.

The VIN is most easily found from outside the vehicle. A person standing on the driver's side can look back into the vehicle at the lower edge of the dashboard where it meets the windshield. A plate containing the VIN is mounted on the dashboard near the lower edge of the windshield.

The VIN can also be found by opening the driver's door and checking the post where the door latches. On that post is a label showing such items as gross vehicle weight and recommended tire pressure. This label also shows the VIN number.
