This number does not represent a permit, certification, or any kind of EPA approval of their activities.EPA assigns an EPA Waste Generator Identification Number to companies that handle regulated wastes. Not all electronics or management processes are regulated by EPA. As a result, not all electronics recyclers are required to have an EPA ID number. The Identification Number is used to track regulated wastes sent from one management facility to another.
