How to Register a Company with EPA 

(Request a Manufacturer Code) 

One of the requirements to use EPA’s Verify computer system is for each company (a 

manufacturer or importer) to acquire an EPA manufacturer code and register that 

code in Verify. This document shows how to obtain and register a manufacturer code. 

I Request a Manufacturer Code through Verify 

EPA assigns a 3-character, alpha-numeric manufacturer code 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. 

If your company does not yet have an EPA-assigned manufacturer code: In order for 

EPA to assign a manufacturer code one person from your company must complete 

Verify’s manufacturer registration process so that your manufacturer code can be 

registered with Verify. 

If your company already has an EPA-assigned manufacturer code: Your company must 

still complete Verify’s manufacturer registration process so that your existing 3-character 

manufacturer code can be registered with Verify. 

A. Create a Verify (CDX) User Account 

Verify uses EPA’s Central Data Exchange (CDX) as the interface for companies to 

submit vehicle and engine compliance information to EPA. The first step of the Verify 

manufacturer registration process is to have one person from your company create a 

Verify (CDX) user account. 

Note: Both companies acquiring a new manufacturer code AND companies who 

already have a manufacturer code but need to register the code in Verify must 

complete all steps in section A below.

1. Go to https://cdx.epa.gov/epa_home.asp. Click on the link in the first bullet, 

“If you are new to CDX and wish to register, please click here.”

Note: This user account will only be used for the manufacturer registration process - it 

will not be used to submit actual compliance information. Separate user 

accounts must be established for submitting vehicle and engine compliance 

information. 

For instructions on creating Verify (CDX) user accounts that will be used to 

submit compliance information for a specific manufacturer, please go to 

www.epa.gov/otaq/verify/setup.htm.

B. To Request a Manufacturer Code for Your Company OR To Enter the 

Manufacturer Code your Company Has in Verify 

After one person from your company has successfully created a Verify (CDX) user 

account (see section A), the next step in the Verify company registration process is to 

request a manufacturer code for your company or enter the code you already have. All 

companies must complete this step, even those that have already been assigned a 

manufacturer code. 

1. Login to the temporary CDX account created in section A. From your 

MyCDX home page, click on the “VERIFY MFR REG: Request 

Manufacturer Code for OTAQ Compliance” link which is listed under the 

Available Account Profiles for the CDX user account that was created in 

section A.I. of this document. If this link is not displayed on your MyCDX 

home page, contact the CDX help desk at (888) 890-1995.

Note: Do not continue in this section until you have created a Verify (CDX) 

user account (see section A). 

Note: Even if EPA has already assigned a manufacturer code to your company, 

you will not be able to submit compliance information to Verify until 

you have completed this section of this document. Pay particular 

attention to Step 2.

2. On the Manufacturer Information screen, fill in all applicable fields about 

your company. 

If your company already has an EPA manufacturer code, enter it in the 

comment field at the bottom of the screen. 

Click the “Review & Submit” button when you have completed the form.

3. Review the information you entered and click the “Return to Form” button 

to return to the data entry screen to make any corrections. If no further 

corrections are needed, click the “Submit” button to send your request to 

EPA. 

Note: Enter as many compliance contacts for your company as applicable. 

Contacts can be included here that will not have a Verify (CDX) 

user account. Entering a contact here is not the same as creating a 

Verify (CDX) user account for that person. 

Note: Only light-duty manufacturers must fill in the division information 

to cover the different “Makes” of vehicle models that a company 

plans to certify. Do not enter general organization divisions.

4. The confirmation page will summarize your request that was submitted to 

EPA for processing. You can print this page for your records.

5. You will receive a notification in your MyCDX Inbox stating that your 

submission was sent to EPA for processing. 

Note: Although EPA tries to respond to all manufacturer code requests in 

less than two business days, it may occasionally take longer if EPA 

receives requests from numerous companies in a short period. We 

appreciate your patience. 

While waiting for EPA’s response, do not submit a duplicate 

manufacturer code request to Verify. This will only delay your 

registration process. If after two business days you have not 

received a status notification in your MyCDX Inbox, you may send 

an e-mail to Verify@epa.gov asking for a status of your 

submission. Please provide the date, time, and transaction 

identifier from your submission confirmation message.

6. Once EPA has processed your request, you will receive a notification in your 

MyCDX Inbox and at your business e-mail address indicating whether your 

manufacturer code request was approved or rejected. If it was approved, this 

notification will include the 3-character manufacturer code that EPA assigned 

to your company. 

Note: Once EPA has assigned a 3-character manufacturer code to your 

company, you have completed the manufacturer registration 

process. You may now begin the Verify (CDX) user registration 

process for anyone who will be submitting compliance information 

to Verify for your company.
