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