Request a Manufacturer Code for the Engines and Vehicles Compliance Information System (EV-CIS)

  • Overview
  • Manufacturer Code Request
  • Account setup
  • Document Types

A manufacturer code is a 3-character, alpha-numeric code that EPA assigns to entities that need to submit information to the Engines and Vehicles Compliance Information System. This includes companies that want to certify their vehicles, engines, or equipment with EPA, or entities that need to submit information such as compliance reports or other information required by EPA. Only one manufacturer code is assigned to each entity, even if that entity plans to certify products from multiple industries.
