What are the numbers assigned to a pesticide product that indicate U.S. EPA approval called?

The numbers assigned to a pesticide product that indicate U.S. EPA approval are referred to as the registration number. This number signifies that the pesticide has been reviewed and authorized for use by the Environmental Protection Agency, ensuring it meets safety and efficacy standards. The registration number is essential for identifying the product and verifying its legal status in the market.

Each pesticide must have this registration number prominently displayed on its label, which allows for tracking and regulation of pesticide products. This system helps ensure that users can find detailed information about the product and its uses, as well as compliance with federal regulations.

The other options do not specifically denote EPA approval: the batch number typically relates to manufacturing, the tracking number can refer to shipping or order processes, and the identification number may have a broader context that lacks the specificity of registration related to pesticide approval.
