    How do I order a Costco Membership?

    Costco has three types of membership: Executive Membership, Business Membership and Gold Star Membership. View details of membership.

    Executive Members earn a 2% Annual Reward on most Costco purchases and receive additional benefits on our member services.

    How do I upgrade to an Executive Membership?

    If you're a Costco member, you can upgrade to an Executive Membership by calling 1-800-220-6000, or by visiting your local Costco warehouse membership department.

Your new membership card will be sent to you, along with a packet explaining the entire menu of business and personal services available in your state.
