How can I look up an EPA number? If I have an EPA number, how do I verify it?

Understanding and verifying EPA identification numbers can be difficult with just the number alone.  EPA issues or assigns many different kinds of identification numbers, such as registration numbers for pesticide products or permit numbers for hazardous waste sites, wastewater discharges, air emissions or other environmentally regulated facilities, businesses, or sites. States or local governments may also assign identification numbers under various environmental regulations.

For information about identification numbers and how to get them, please see the following FAQ:

If you would like to look up the permit number for a facility or business, you may be able to use the Facility Registry System in the Envirofacts database. The Facility Registry System (FRS) is a centrally managed database that identifies facilities, sites or places subject to environmental regulations or of environmental interest.

Facility Registry System (search by name or ID number): http://www.epa.gov/enviro/html/fii/fii_query_java.html

If you want to search for a registered pesticide product, please go to EPA's Frequent Question about pesticide registration numbers:

What is a pesticide registration number? Where can I look up information about a pesticide if all I have is the registration number? Where can I locate information about a pesticide label?:
