Vehicle and Engine Certification

Company Registration for the Engines and Vehicles Compliance Information System (EV-CIS)

A manufacturer code is a 3-character, alpha-numeric code that EPA assigns to each company that wants to certify their vehicles or engines with EPA. Only one manufacturer code is assigned to each company, even if that company plans to certify products from multiple industries.

NOTE: All companies must electronically register for a manufacturer code through the Engines and Vehicles Compliance Information System (EV-CIS) even if they have already been assigned a code by EPA.

Follow these steps to electronically register a company for a manufacturer code:

STEP 1: Create a temporary user account for EV-CIS MFR REG.

Manufacturer code requests are submitted electronically through EPA's Central Data Exchange (CDX) EV-CIS and require one user to create this temporary user account.

For step-by-step instructions, read Section A in: User's guide for registering a company

STEP 2: Electronically register your company's manufacturer code.

Complete this step to register an existing code in EV-CISOR request a new manufacturer code.

For step-by-step instructions, read Section B in: User's guide for registering a company

STEP 3: Receive status notification from EPA.

After EPA reviews the request, you will receive an email and a notification in your MyCDX inbox indicating whether your manufacturer code request was approved or rejected. If approved, the 3-character code will be included in the notification.

STEP 4: Begin account setup for EV-CIS.

Once your manufacturer code is successfully registered electronically, you can begin the account setup process to establish users in your company.
