How many people can be on my Costco membership?
A total of two people can be on a Gold Star Membership (either regular or Executive): one Primary Member and one free household member who is over 16 and lives at the same address. If you are the Primary Member, we leave it up to you to decide who receives the second card—something you can change at any time by visiting your Account Details or the membership counter at your local Costco.
The notable difference between Gold Star Membership and Business Membership is that the Primary Member on a Business Membership can add more than one person for an additional fee.
