How do I update my address or personal information on my Costco account?

To update your address or personal information on a Costco account, a member can log into their account by visiting the official Costco website. Once logged in, the member should navigate to the "My Account" section, where they will find options related to personal information. In this section, there are specific areas designated for editing personal details, including the address. After making the necessary changes, it is important for the member to save the updates to ensure that the new information is processed correctly. For those who prefer to handle changes via mobile, the Costco app also accommodates similar functionalities, allowing members to manage their accounts on the go. If a member encounters any unique issues, they may find helpful information on the Costco website or in the customer service section, which can provide additional guidance. It is always a good idea to verify that all details are accurate and up to date, especially for shipping and billing purposes.
