Which of the following indicates a product's registration for pesticides?

• A. Registration number
• B. Expiration date
• C. Color of container
• D. Manufacturer's address

Answer: (A)

The key idea here is that regulatory approval is shown by a registration number on the product label. That number is a unique identifier assigned by the pesticide regulator (PMRA in Canada and Alberta’s framework) once the product and its label have been evaluated and approved. It confirms the product is legally registered for use and that you’re following the approved label directions. The other details don’t indicate registration: an expiration date relates to shelf life, not regulatory status; the color of the container can vary with packaging changes; and the manufacturer’s address is just contact information, not proof of registration. So, the registration number is the clear signal that the product is registered for pesticides.
