Electronic Certificate of Conformity (e-CoC) for Vehicle Registration Tax (VRT)

The e-CoC service allows you to upload, or manually input, an e-CoC for your vehicle. You can also search for, or amend, an existing e-CoC.

Vehicle manufacturers produce a unique Certificate of Conformity for every vehicle they make. It shows type approval compliance and certain vehicle information.

Since 12 September 2016, all new motor vehicles registered by Revenue are legally required to have an e-CoC. This must be submitted on the Revenue website before you register the vehicle.

Who is the service for?

This service is for individuals and registered business users. You must be registered for either myAccount or the Revenue Online Service (ROS) to use the e-CoC service.

Business users have the option to bulk upload e-CoCs through ROS.
