Do Not Sell My Personal Information
By submitting your last name and membership number below, you will be opted out of having your personal information sold to third parties by Costco. The California Consumer Privacy Act (CCPA) defines “sale” very broadly to include simply making data available to third parties in some cases. PLEASE NOTE: A Do Not Sell request does not opt you out of Costco marketing. To opt out of Costco marketing, sign into your account on costco.com or visit the membership counter at any US or Puerto Rico Costco warehouse.
