How to obtain a copy of a Certificate of Conformity for a light-duty vehicle (car, truck, or motorcycle)

A Certificate of Conformity is the document that EPA issues to a vehicle manufacturer to certify that a vehicle class conforms to EPA requirements. Every class of motor vehicle introduced into commerce in the United States must have a Certificate of Conformity. Certificates are valid for only one model year of production.

If you are exporting a motor vehicle from the U.S. to another country, they may require certification data for your motor vehicle. A Certificate of Conformity and Certificate Summary Information (or summary sheet data) will contain the emission standards the motor vehicle was certified to.

To request or find a Certificate of Conformity or Certificate Summary Information sheet, you need to know the Test Group number (for light-duty cars and trucks – model year 2001 or later) or the Engine Family number (for pre-2001 light-duty cars and trucks). This information is listed on the “Vehicle Emission Information” label/sticker located under the vehicle’s hood. The number has 11 characters using both numbers and letters. If your vehicle is missing the emission label you may be able to order a new one from your U.S. dealer or you can contact the manufacturer directly for the Test Group number for your particular vehicle.

Certificates of Conformity and Certificate Summary Information sheets are available on EPA’s Web site for model years 2003 and later.
