What changes can I make to my Costco membership online?

Costco members can make several changes to their membership online, such as:

  • Renew
  • Upgrade to Executive Membership
  • Add or change Household cardholders
  • Update address, phone number and email
  • Change communication preferences


To get started, verify your membership at a Costco membership counter, or at Costco.com.

For a legal name change, please visit your local Costco membership counter and present your new government-issued photo ID. At that time, one of our helpful employees will be happy to update your information and provide you with a new membership card.

If you're wanting to reverse your Executive Membership, visit here for more details.
