How do I register to shop on Costco.ca?

If you have not registered on Costco.ca before, you will need to click on "Sign In or Register" found near the top right corner of the Home page.

Enter your e-mail address, password and, if you are a member, the membership # found on your membership card. If you have a Costco - American Express co-branded card, your membership number is located on the back of your card to the right of your picture and will say "Costco Membership Number."

Note: Maintaining an active Costco membership does not automatically register you on Costco.ca. You will need to complete a New Registration if you have not previously registered on Costco.ca.

Your membership number is not linked to your account until you add it at the time of registration or by updating your information in the My Account section.
