VIN Verification

Vehicle Identification Number (VIN) Verification

If your vehicle has never been registered in the state of Colorado you must obtain a Vehicle Identification Number (VIN) verification prior to registration. VIN Verifications may be obtained at any Air Care Colorado inspection station. If your vehicle requires an emissions inspection, simply let the inspector know that you need a VIN verification as well as an inspection. If your vehicle does not require an inspection, do not drive into the testing lanes, please ask for a VIN verification inside the station office. VIN verification fee: $20. 

The following provide VIN verifications:

  • Centralized Air Care Colorado emissions inspection stations.
  • Independent emissions inspection stations in both the Enhanced and Basic emissions program areas.
  • Licensed diesel emissions inspection stations.
  • Some motor vehicle dealerships.
  • Some County Clerk and Recorder offices.
  • Some law enforcement agencies.

Important Note: Some county clerks and law enforcement agencies do not provide this service. Call ahead to make sure this service is available before going to a county clerk's office or law enforcement agency for a VIN verification. For more information on the VIN verification requirement, call the Colorado Division of Motor Vehicles at 303-205-5603 or your county motor vehicle office.

When does a 'new to Colorado' vehicle NOT require an inspection?

If the vehicle you are bringing into the program area is six years old or newer, or is brand new and has never been registered in any state, you do not need an emissions inspection. If the vehicle has never before been registered anywhere in the state of Colorado, you will need a VIN verification.

Do not drive the vehicle into the testing lanes for a VIN verification; request a VIN verification at the office.

Information for New Residents

If you are bringing a vehicle into the Denver-Boulder and North Front Range emissions program area from another state or another part of Colorado, including a basic emissions program area, you are required to obtain an emissions inspection and register your vehicle in your new county within 90 days of establishing residency. In addition, you may need a Vehicle Identification Number (VIN) verification.

When a newer vehicle is brought into the program area and is less than seven (7) years old (from Manufacturer Statement of Origin) the vehicle does not require an emissions inspection at the time of registration. The vehicle will require an emissions inspection when it reaches its eighth (8) model year.

Change of Ownership Requirements

Used vehicles that are for sale are required to have a new emissions inspection, even if the current inspection report still has time on it. However, there is an EXCEPTION to this rule:

  • If a newer used vehicle is sold and there are 365 days or more left on the original seven (7)-year exemption, the vehicle does not require a new inspection at the time of sale.

It is the seller's responsibility to obtain the inspection. This is a consumer protection for the buyer. The seller must provide the emissions inspection paperwork to the buyer for vehicle registration purposes. The buyer must use this paperwork to register the vehicle within one year.  A vehicle dealer may offer customers a voucher enabling the buyer to obtain an inspection for free. The customer has the right to refuse this arrangement.

If you purchased a vehicle from a dealer and used a dealer voucher to obtain an inspection, and the vehicle failed the test, access our Dealer Information.
