Do 55 have a vin on the frame?

1955 Chevrolet cars do not have a VIN on the frame. The Vehicle Identification Number (VIN) was first introduced in 1954, but it was not until the 1968 model year that it became mandatory for all vehicles sold in the United States. Prior to 1968, manufacturers used their own unique identification numbers, which were often stamped on the engine or firewall of the vehicle.
