Frequent Questions

What is a pesticide registration number, and where can I look up information on pesticide registration and labeling?

Pesticides must be registered or exempted by EPA’s Office of Pesticides Programs (OPP) before they may be sold or distributed in the United States. The EPA Registration Number and the Establishment Number are required on all pesticide products. The purpose of these identification numbers is to provide a unique product number for regular registrations, distributor registrations, Special Local Needs registrations, and Experimental Use Permits. The EPA Registration Number indicates which company holds the registration for the pesticide product, and in which sequence the product was submitted to EPA by the company.

Further information is available in EPA’s Label Review Manual.

For additional information about the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the different types of pesticide registrations provided, please see:

For general information about pesticide registration, including the process and fees for registering a pesticide, please visit EPA’s Pesticide Registration Web sites.

To search for EPA registered pesticide products by product name, ingredients, company information, or EPA ID number, you can access Purdue University’s National Pesticide Information Retrieval System (NPIRS). NPIRS offers a free search of several states’ registration data. It is intended for information purposes only and does not confirm registration status.

The Pesticide Product Label System (PPLS) is a collection of images, in multi-page TIFF format, of pesticide labels which have been approved by OPP under Section 3 of FIFRA. The collection contains the initially approved label for pesticide products registered under FIFRA Section 3 as well as subsequent versions of labels which have changed via amendment or notification. PPLS is searchable by registration number.
