How to Request an EPA Manufacturer Code
Each company1 that needs to use EPA's Engines and Vehicles Compliance Information System (EV-CIS)
must obtain an EPA manufacturer code and register that code in EV-CIS. This document shows how to
obtain and register a manufacturer code.
EPA assigns a 3-character, alpha-numeric manufacturer code to each company that wants to certify their
vehicles, engines, or equipment with EPA, or to submit information such as compliance reports or other
information required by EPA. Only one manufacturer code is assigned to each company, even if that
company plans to certify products from multiple industries.
If a company does not yet have an EPA-assigned manufacturer code, that company will need to have one
assigned to it. For EPA to assign a manufacturer code, one person from that company must complete the
EV-CIS manufacturer registration process.
This document is divided into two sections. Section A outlines the process for creating an EV-CIS user
account through the Central Data Exchange (CDX) that will be used to request a manufacturer code.
Section B outlines the process for requesting an EPA manufacturer code once an EV-CIS user account has
been created.
A. Create an EV-CIS CDX User Account
EV-CIS uses EPA's CDX as the interface for companies that need to submit information to EV-CIS. The first
step of the EV-CIS manufacturer registration process is to have one person from your company create an
EV-CIS (CDX) user account.
For instructions on creating EV-CIS (CDX) user accounts that will be used to submit certification and
compliance information for a specific manufacturer code once it has been issued, please go to
https://www.epa.gov/ve-certification/account-setup-engines-and-vehicles-compliance-information-
svstem-ev-cis.
NOTE: The CDX user authentication process includes Multifactor Authentication (MFA) through the US
Government's Login.gov solution. If you have not already done so, you will be required to create a
Login.gov account to create and access your CDX account(s). For more information, please visit
https://login.gov/.
1 For the purposes of this document, the term "company" will be used to refer to any individual, business,
manufacturer, importer, or other entity that needs to use EV-CIS to submit certification and compliance information
to the EPA.
