How Can I Make Changes to My Membership Account?

As long as you are the Primary Member or Account Manager, your membership can be adjusted a couple ways:

  • To adjust your membership online, simply sign in here and head on over to Account Details.  
  • Contact our Member Service team by using the "Contact Us" section on the left of this page.

Of course, you can always visit Costco in person at your local warehouse and a member of our team will be happy to assist you.
