What is the CA# on a label and what does it stand for?
The CA# on a label is used in Canada as an identifier for the Canadian dealer (manufacturer, importer, or seller of the product) in place of the company name and address. Businesses can register for a CA number through the Canadian Competition Bureau. The CA# is similar to the RN# used in the United States to identify U.S. companies.
