How Do You Add Your Membership Number on Costco.com?
You can add your Costco membership number when you create an account online or add it anytime later.
Linking your membership to your Costco account will mean you earn rewards on your executive membership and have access to “Member Only” items.
Adding a membership number is an optional step when creating an account on Costco.com.
However, we recommend adding your membership number right away to enjoy the benefits of shopping as a Costco member.
If you choose not to add it right away or purchase a membership after you have already created an account, follow these steps to add your membership number:
Step 1. Go to the “Account” section of the website or the app.
Step 2. Click “Account Details.”
Step 3. Scroll down to see the section to add your membership number. The best place to find your membership number is on the back of your Costco card (It is a 12-digit number).
Step 4. Choose “Add Membership Number Only” or “Verify Membership” to complete the process. Member verification is an additional process that is not required to shop online.
Members should be aware that you do not automatically have a registered account on Costco.com when you sign up for the membership.
You must register and link your membership number to take advantage of your membership benefits while shopping online.
Once your membership number is added to a Costco.com account, all online purchases will be connected to your membership number.
Do You Have to Create an Account to Order Online at Costco?
It is required to create an account on Costco.com to shop online. However, membership is not required to create an account or shop online at Costco.
Anyone can shop online at Costco if they have registered for an account.
However, there are a few restrictions for Costco non-member shoppers, including:
- Non-members pay a 5% surcharge on all items. This makes up for some of the difference in the cost of the membership Costco would be receiving.
- Certain items are restricted as “Member Only” items. You can view these items as a non-member but cannot see the price of items or add them to your cart unless you are shopping with an account linked to a membership number.
- Select sales, discounts, or deals may not be available for non-members.
If you want to get the best deals and selection of items when shopping with your Costco account, it may be worth considering a membership.
Not only do you avoid the 5% surcharge, which can add up quickly, but you also can earn 2% rewards on every purchase with the Executive membership.
