Costco Membership Referral Program 2026: Earn Digital Shop Cards by Referring Friends

Costco is one of those rare things in retail — a place where the more you use it, the more you appreciate it. If you have been a member for a while, you have probably already told a friend or colleague they should join. The Costco Refer-a-Friend program makes that recommendation worth something tangible. When you bring a friend to sign up for a new membership, you both walk away with a Digital Costco Shop Card — real money to spend at any U.S. Costco location.
How the Costco Referral Program Works
The process is refreshingly simple compared to most referral programs. There is no app to download, no special link to generate, and no complicated tracking system. You physically bring your friend to any Costco Membership Counter and they sign up for a new membership right there with you present.
Once both of you enroll in auto renewal on a Visa card and provide a valid email address at the time of sign-up, the Digital Costco Shop Cards are issued to both of you. The whole thing takes about as long as a normal membership sign-up — a few minutes at the counter.
The offer is valid at any U.S. Costco location and runs through December 31, 2026.
How Much Do You Get?
The reward amount depends on which membership tier your friend chooses:
Executive Membership — both you and your friend each receive a $40 Digital Costco Shop Card.
Gold Star Membership — both you and your friend each receive a $20 Digital Costco Shop Card.
The Shop Card lands in your inbox after sign-up and can be used like cash on your next Costco visit — in-store or online at Costco.com. There is no minimum spend requirement to use it, and it works on almost anything in the warehouse.
It is worth noting that separate referral forms are required for each referral, and the program is only open to new members. You cannot use this program to refer someone who is renewing an existing membership or reactivating a lapsed one.
What Is the Difference Between Gold Star and Executive Membership?
If your friend is on the fence about which tier to choose, it helps to understand what each one offers — because the right choice affects both their savings and your Shop Card amount.
Gold Star Membership costs $65 per year and is the standard entry point. It gives full access to any Costco warehouse, Costco.com, and the Costco app. Members can shop across all departments including pharmacy, optical, tire center, and more. It also comes with the option to add a household card for free.
Executive Membership costs 1,250 per year (this cap was raised with the 2024 fee adjustment). If your friend shops at Costco regularly, this reward can easily offset the higher annual fee and then some.
For example, if your friend spends 120 — nearly covering the full cost of the Executive Membership. Any member who shops frequently is almost always better off going Executive.
From a referral standpoint, encouraging your friend to sign up for Executive also doubles your Shop Card from 40, which is a nice bonus on top of helping them make the smarter financial choice.
The Two Requirements to Receive Your Shop Card
There are two conditions that both you and the new member must meet to receive the Digital Shop Cards:
1. Provide a valid email address at sign-up. The Shop Card is digital and delivered by email. Without an email address on file, there is no way for Costco to send it to you.
2. Enroll in auto renewal using a Visa card. This must be done at the time of sign-up at the counter, not after the fact. Auto renewal means the membership fee is charged automatically each year, so the membership never lapses. Costco requires this to be set up on a Visa card specifically — other payment methods do not qualify for the referral reward.
If either condition is missed during sign-up, the Shop Card will not be issued. So it is worth confirming both steps are completed before you leave the counter.
Who Is Not Eligible?
A few categories are excluded from the program:
- Costco employees are not eligible to participate, either as referrers or as new members using this offer.
- Renewing members do not qualify. The referral program is strictly for brand-new Costco memberships only.
- Members outside the U.S. — the rewards and structure described here apply to U.S. locations. Canada and the UK have their own versions of referral incentives with different reward structures.
Costco Referral Rewards in Other Countries
For readers outside the United States, Costco runs similar programs in other markets, though the rewards differ:
Canada — new Executive Members receive a **150), while new Gold Star Members receive a $25 online voucher. Referring members in Canada receive the same voucher amounts as the new member they bring in.
United Kingdom — both the new member and the referring member receive a £10 Costco shopping voucher plus a complimentary Kirkland Signature Hot Dog and Soda upon joining.
Why the Referral Program Makes Sense for Costco
Costco has one of the most impressive membership retention rates in retail — consistently above 90% year after year. That kind of loyalty comes from real value, not marketing gimmicks. With 137 million cardholders globally and a business model built on membership revenue rather than product margins, Costco grows primarily through word of mouth.
The referral program formalizes what has always been happening naturally — members telling people they know how much they save at Costco. By adding a financial reward to that conversation, Costco accelerates what was already working. The cost of a $40 Shop Card per new Executive member is far below what most retailers pay to acquire a new customer through traditional advertising.
For the member doing the referring, it is a no-effort reward. You are already shopping there. You already talk about it. The only difference now is that you take your friend to the counter with you.
Is It Worth Referring Someone to Costco?
Yes — particularly if the person you refer becomes an active shopper. Your 40 Shop Card is a one-time reward, but the real value is in knowing you helped someone access genuine savings on groceries, household goods, electronics, fuel, and services they were probably already buying elsewhere at higher prices.
Executive Membership tends to pay for itself within the first few months for anyone who buys groceries, fills up their gas tank at Costco, or uses Costco Travel. Referring someone to the right tier can save them hundreds of dollars over the course of a year.
If you have friends or family members who have been curious about Costco but never pulled the trigger, the current referral offer — valid through the end of 2026 — is a good reason to finally make the trip together. You both get a Shop Card immediately, and they get access to a warehouse full of reasons to keep coming back.
