How to Register for the Verify System

Verify 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.

There are two parts to registering for the Verify system:

Part 1: Company registration for Verify
