How to Qualify

  1. Choose Your Signup Route The public offer gives the new member a larger voucher at both tiers. Choose one route; the offers cannot be combined.
  2. Join Costco Referral: join at a Canadian Membership Counter with an existing member. Public offer: use NMEMB100 for Executive or NMEMB50 for Gold Star.
  3. Redeem on Costco.ca Use the voucher in one eligible Costco.ca order above your route's minimum, before expiry.

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, the public offer gives twice the Costco.ca voucher value. The referral rewards both the new and existing member. Choose one route; Costco says the offers cannot be combined.

Purchase thresholds differ by route and tier. Executive public signups can also qualify for a separate $65 CIBC Costco Mastercard statement credit when the card is approved the same day and $65 in net purchases posts within 120 days.

Is There a Costco Canada Referral Code?

No Shareable Referral Code

Costco's current Canadian Refer a Friend flow is completed in person. There is no public referral code or referral link to add before or after signup; the existing member and friend present Costco's referral page at the Membership Counter.

  1. No Shareable Referral Code Costco's current Canadian Refer a Friend offer does not publish a personal code or link that can be copied from this page.
  2. The Referral Is In Person The existing Costco member must bring the friend to a Canadian Membership Counter. When the friend joins, present Costco's Refer a Friend page to the Membership Clerk.
  3. Joining Without a Referrer? If you are joining independently, compare Costco's current public new-member offer first. Costco currently lists NMEMB100 for Executive and NMEMB50 for Gold Star.

Costco Offer FAQ

What is the Costco Canada referral code?

Costco's current Canadian Refer a Friend offer does not use a shareable referral code. The existing member and the new member must complete the referral together at a Costco Membership Counter in Canada.

Is the Costco referral better than the public new-member offer?

For the new member alone, Costco's current public offer provides the larger voucher: $100 for Executive with NMEMB100 versus a $50 Executive referral voucher, and $50 for Gold Star with NMEMB50 versus a $25 Gold Star referral voucher. The referral gives the other $50 or $25 to the existing member.

What are Costco promo codes NMEMB100 and NMEMB50 for new memberships?

They are Costco Canada membership promo codes for new members. NMEMB100 gives an Executive member a $100 Costco.ca voucher for one purchase over $250; NMEMB50 gives a Gold Star member a $50 voucher for one purchase over $150.

Can I combine the Costco referral with NMEMB100 or NMEMB50?

Do not count on combining them. Costco's current Refer a Friend terms and public new-member offer terms each say the offer may not be combined with another offer.

Who qualifies for the Costco referral or new-member offer?

Costco says the current offers are for new members or people whose previous Costco membership has been expired for at least 18 months.

Can the Costco online voucher be used in a warehouse?

No. Costco's current terms say the voucher is for Costco.ca and is not valid in Costco warehouses. The terms also exclude several other channels and purchase types, including Costco Business Centres, Instacart, Same-Day, Uber Eats, travel, tires, memberships, renewals, Shop Cards and gift cards.
