Request for Catalytic Converter Assigned Identification Number

Maine law requires all detached catalytic converters be permanently marked with the vehicle identification number from the vehicle the catalytic converter was removed from. 

If you are in possession of a catalytic converter that has been removed from a motor vehicle and the vehicle identification number of the motor vehicle from which the catalytic converter was removed cannot be identified or the catalytic converter is too damaged to mark in a permanent and legible manner, you can request that the Secretary of State assign a new identification number to the catalytic converter.

If you require an assigned identification number for a detached catalytic converter, complete the Unmarked Catalytic Converter Complaint Petition.
