What is the significance of EPA registration numbers on product labels?

• A. They indicate federally registered products and are required for legal sale and use.
• B. They identify the color of the product label.
• C. They show the batch number.
• D. They are optional.

Answer: (B)

EPA registration numbers show that a product is federally registered and legally approved for sale and use. Under FIFRA, every pesticide marketed in the United States must be registered with the EPA, and the label must display the EPA registration number. This number confirms the EPA has reviewed the product for safety, labeling, and approved uses, and it helps authorities track and enforce compliance. It isn’t related to the color of the label, it isn’t a batch or lot number, and having a registration is not optional. If a product lacks an EPA registration number, it isn’t legally marketable or usable.
