Costco Referral Code Canada 2026: No Shareable Code

Costco Canada does not use a shareable referral code for its current Refer a Friend offer. An existing member must bring the new member to a Canadian Membership Counter. If you're joining independently, Costco currently advertises NMEMB100 for a $100 Costco.ca voucher with Executive membership and NMEMB50 for a $50 voucher with Gold Star.

How to Qualify

  1. Choose Referral or Public Offer Compare Costco's in-person Refer a Friend route with the separate public new-member offer before joining. The public offer currently gives the new member more voucher value at both membership tiers.
  2. Join Costco Referral route: visit a Canadian Membership Counter with an existing member and show Costco's Refer a Friend page. Public route: use NMEMB100 for Executive or NMEMB50 for Gold Star when buying the membership.
  3. Use the Voucher Online Use the resulting Costco.ca voucher in one eligible online transaction above the required purchase threshold before the voucher expires.

Costco Referral vs Public New-Member Offer

Public Offer Gives the New Member More
Public New-Member OfferExecutive $100 · Gold Star $50
Refer a FriendExecutive $50 each · Gold Star $25 each

For the new member alone, Costco's current public offer is worth twice the referral voucher at each tier. The referral splits the same headline value across two people: $50 + $50 for Executive or $25 + $25 for Gold Star. Both current Costco offers say they cannot be combined with another offer.

The public vouchers require a Costco.ca purchase over $250 for Executive or over $150 for Gold Star. The referral vouchers require a Costco.ca purchase over $200 for Executive or over $125 for Gold Star for each recipient.
