My Account & Orders

Our costco.co.uk website is available to you whether or not you are a member of our Costco Warehouse club – but you need to register first to shop, which only takes a few seconds.

Maintaining an active Costco warehouse membership does not automatically register you on costco.co.uk. You will need to complete a New Registration if you have not previously registered on costco.co.uk.

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

My Account is where all your details are stored: details, address book, orders, marketing preferences and your wishlist.

You can:
  • Add multiple delivery and payment addresses
  • Change your security password
  • Check the status of recently placed orders
  • View your order history (fig.1)
  • Update your marketing preferences
