How to Register for Engines and Vehicles Compliance Information System (EV-CIS)

Engines and Vehicles Compliance Information System (EV-CIS), formerly the Verify System, is EPA's compliance information system for:
  • Engines;
  • Vehicles; and
  • Equipment used in transportation and other mobile source applications.

Engine, vehicle, and equipment manufacturers use this system to report certification and compliance information for emissions and fuel economy.
