If your vehicle is not currently registered in the state of Colorado, a Vehicle Identification Number (VIN) verification is required prior to registration. A VIN verification may be obtained at any Air Care Colorado inspection facility. If your vehicle also requires an emissions inspection, simply let the inspector know that you also need a VIN verification at the time of inspection. If your vehicle does not require an inspection, do not drive into the inspection lanes. Simply ask for a VIN verification inside the office. The VIN verification fee is $20.
