Before Chevrolet VINs were standardized, there were several numbers that could be used to identify these vehicles, including engine codes, cowl tags, RPO codes, and paint codes. Trim codes were also utilized, and at the end of the trim codes, there would be an exception control letter (ECL). In the 1950s, Chevrolet VIN decoders were comprised of the Tri-Five serial numbers, but today Chevrolet VIN decoding utilizes the standardized 17-digits across the auto industry.
There are several places to look in a Chevrolet VIN decoder search. The standard location for all automobiles is on the driver’s side of the windshield, on the front corner of the dashboard, but there are other locations as well depending upon the model.
For example, in a Chevrolet Camaro, the VIN can also be found in the trunk on the identification label. On the Captiva, the Chevrolet VIN is found in three other locations: 1) on a silver sticker near the bottom of the pillar on either the passenger or driver’s door; 2) stamped on the chassis below the bonnet, near the top center of the bulk head; 3) on the middle center of the engine block. For the Aveo, the VIN can be found to the left of the bonnet slam panel’s catch, stamped upon the bulkhead’s center, and on the gearbox towards the front right for the purposes of a Chevrolet VIN engine decoder.
