Free Catalytic Converter Marking Kits

Boulder County, Colo. - The Boulder County Sheriff’s Office has partnered with the Colorado Auto Theft Prevention Authority (CATPA) to combat catalytic converter theft and will be distributing free CatETCH labels to community members. The CatETCH labels each have a unique identifying number that can be applied to a catalytic converter by the vehicle owner or a mechanic. Catalytic converter labeling will allow identification of your catalytic converter in the event it is stolen and later recovered by law enforcement. The unique identification code is entered into a federal database.

Community members are required to complete a registration form, please follow this link Registration Link, prior to picking up their kit. During the registration process we will be collecting the community members email address, zip code, vehicle year, vehicle make and model, license plate number, vehicle identification number, and resident’s city. Up to three vehicles can be registered at a time.
