This alphanumeric combination * * * has 30 digits, so it is guaranteed that vehicles will not have duplicate frame numbers within 30 years. Starting with the code A corresponding to 1980, and so on, the production year of the vehicle can be found.
Extended data:
1. In the lower right corner of the front windshield, there is a large frame number, which is a series of data mixed with letters and numbers.

There are some frame numbers on the threshold of the co-pilot door, which are written on a piece of metal.
There is also a kind of car, such as a big truck, like the first four and the last eight, or a half-length train. The frame number is on the girder below the rear hopper.
