We look forward to serving you as a Costco member. If you have any questions, please ask our member services personnel at any Costco membership counter or click Customer Service. Costco membership is subject to our Member Privileges & Conditions, which may change from time to time without prior notice.

Membership

  • Membership is available to all qualifying individuals 16 years of age and over.
  • Costco reserves the right to refuse membership to any applicant, and membership may be terminated at Costco's discretion and without cause.
  • Membership is subject to any and all rules adopted by Costco, including our privacy policies and practices, and they may be amended from time to time without notice.
  • Members are required to present a valid photo identification issued by the Federal, State, or Provincial governments of the United States, Puerto Rico or Canada or any valid passport or consular card to sign up for membership.
  • U.S. Members must have a valid U.S. address or U.S. P.O. Box for the mailing address on their membership. Canadian Members must have a valid Canada address or Canadian P.O. Box for the mailing address on their membership.

Membership Cards and Fees

  • Membership fee is for one 12-month period from the date of enrollment of the Primary Cardholder.
  • Your membership card is valid at any Costco warehouse worldwide and is not transferable.
  • You will be required to scan your membership card at the front door scanner when entering any Costco warehouse and show your membership card when checking out at a payment register. Bar codes, photos or other copies are not acceptable.
  • Your membership card must have a card number and recognizable, unobstructed full-face photo to be valid. If your photo is not on your card, only passports, as well as photo identification issued by the United States, Puerto Rico, Canadian Federal, State, or Provincial governments are acceptable forms of identification.
  • Report lost or stolen cards to any Costco membership counter immediately or call 1-800-774-2678.
  • Cards remain the property of Costco and must be returned upon request.
  • Primary and Affiliate Members receive one additional card for one designated member of their household, who is 16 years of age or older and living at the same address. When they receive their membership card, the designated household member must live at the same address as the Primary or Affiliate Member and must have their photo taken and added to their card.
  • Limit one Gold Star and one Business Membership, if applicable, per person. Costco reserves the right to treat businesses with the same or similar addresses or with identical, similar or related ownership as a single business and as such, limited to a single membership. Costco reserves the right to refuse, decline, or cancel a membership at any time.
  • Certain merchandise, including prescription drugs and alcoholic beverages in some states, may be purchased by nonmembers where required by law.
  • Certain merchandise may be purchased online by members or nonmembers. A nonmember pays 5% more than members for such merchandise. Online prices may exceed warehouse prices.

Renewing, Adding or Deleting Cards

  • Renewal fees are due no later than the last day of the month your membership expires. You may remit your renewal fee by mail, online at Costco.com, or at any warehouse. Costco members may charge their membership fees automatically on any Visa® credit/debit card or Mastercard debit card. That card will be charged on the first day of your renewal month. If you have not signed up for auto renewal, your membership fee will be added to your first purchase at the warehouse after expiration.
  • Membership renewal must be completed for all cardholders on the membership when the renewal is processed.
  • You will not receive new membership cards each year.
  • Memberships renewed within 2 months after expiration of the current membership year will be extended for 12 months from the expiration date. Memberships renewed more than 2 months after such expiration will be extended for 12 months from the renewal date. All renewals will be assessed at the membership fee in effect on the date the membership fee is paid.
  • The Primary Member is responsible for the membership, and must authorize cardholder changes, including additions or deletions.
  • The Primary Member may designate a current Costco member as a Personal Administrator or Business Administrator to make changes to the membership. Administrators are authorized to change the address, phone number, update communication preferences, and upgrade or renew the membership. The Administrator cannot remove the Primary Member or change Affiliate Members' personal information.
  • Primary Business Members or Business Administrators may add additional Cardholders (Affiliates) to their membership. To add Affiliates to your Business Membership, visit the membership counter at any warehouse.
