• A “company number” is a unique identifier assigned to a company that wishes to register a pesticide with the EPA.
• Registrants must obtain a company number prior to registering their first product with EPA.

A “company number” is a unique identifier assigned to a company that wishes to register a pesticide (e.g., herbicide, rodenticide, or antimicrobial) with the Environmental Protection Agency (EPA). A company number is also necessary for a company that plans to produce pesticides or devices. Such production requires the company to obtain a “Pesticide-Producing or Device-Producing Establishment Number.” The company number is part of the establishment number.

How to obtain an EPA company number

Registrants must obtain a company number prior to registering their first product with EPA. For subsequent products or amendment to existing registrations, the registrant must refer to this company number. (Note: Registrants who plan to produce their own products will also need to obtain an “establishment number.”)

The registrant must submit a signed letter on company letterhead to request a company number and establish an official address with EPA as described in the agency’s guidance, “How to Obtain a Company Number and Register an Official Address.” EPA will direct all future correspondence to the official address. The registrant must keep this official address record up to date.

In its request for a company number, a foreign company must designate a U.S. agent to receive correspondence and represent it in matters concerning an application. A U.S. registrant may also designate an agent. The letter should include a statement authorizing the agent to act in all matters concerning the registration of the product with EPA. It should also include a statement acknowledging that all official correspondence from EPA will be directed to the agent.

The request for a new company number can be made via email with the signed letter on company letterhead (including all needed information) as an attachment.

How to obtain an EPA establishment number

When producing or formulating a pesticide, it is necessary to register the place or facility where the pesticide or device will be produced. To register an establishment, EPA Form 3540-8, Application for Registration of Pesticide-Producing Establishments must be completed and submitted to EPA as follows:

• For domestic establishments, the completed application should be sent to the EPA Regional Office having jurisdiction over the state in which the company headquarters is located. The instructions for Form 3540-8 list the Regional Offices’ mailing addresses and telephone contacts.
• For foreign establishments, applications should be submitted to EPA headquarters at the address listed in the instructions on how to properly complete Form 3540-8.

To request termination of a pesticide-producing or device-producing establishment, domestic establishments should notify the EPA Regional Office having jurisdiction over the state in which the company headquarters is located. Foreign establishments should notify the EPA Headquarters Office listed in the instructions for Registering Establishments on the EPA website.
