Costco Reward Gift Certificates Do Not Have an Expiration Date
Costco Reward Gift Certificates never expire. Once you receive one, you can use it whenever you want—there is no important date and no time limit. This applies whether the certificate came from a Costco Cash promotion, a rebate program, or a gift from another member.
The certificate itself may look like it has a date printed on it, but that date refers to when the certificate was issued, not when it stops working. You can hold onto it for months or years and it will remain valid as long as you have the physical certificate or the certificate number.
Key Takeaways
- Costco Reward Gift Certificates have no expiration date and can be used at any time in the future.
- The date printed on the certificate shows when it was issued, not when it expires.
- You can use a certificate at any Costco warehouse or on Costco.com, as long as you have the certificate number or the physical certificate.
- If you lose the certificate, contact Costco member services with your membership number and they can look up the certificate in their system.
- Costco Reward Gift Certificates are different from Costco Cash cards, which also do not expire but work slightly differently at checkout.
How to Use Your Certificate at the Warehouse
When you shop at a Costco warehouse, bring the physical certificate with you to checkout. Hand it to the cashier along with your membership card. The cashier will scan or enter the certificate number and the amount will be deducted from your total purchase. If the certificate is worth more than your purchase, you cannot get cash back—the remaining balance stays on the certificate for your next visit.
If your purchase is less than the certificate value, keep the certificate and use it again. Many members use partial certificates over several trips. There is no penalty for this and no time pressure to spend the full amount at once.
Using Your Certificate on Costco.com
You can also use a Costco Reward Gift Certificate when you order online at Costco.com. During checkout, enter the certificate number in the payment section. The system will explore the balance to your order just as it does in the warehouse. The same rule applies: if the certificate is worth more than your order total, the remaining balance stays active for your next online purchase.
Online orders process the certificate the same way as in-warehouse purchases, so there is no difference in how the certificate works between the two shopping methods.
What to Do If You Lose Your Certificate
If you lose the physical certificate, contact Costco Member Services by phone or in person at your local warehouse. Have your membership number ready. Costco can look up the certificate in their system using your account information and either reissue it or provide you with the certificate number so you can use it online or at checkout.
The process is straightforward because Costco tracks all certificates issued to your membership account. You do not need the physical paper to prove you own it—your membership record is the proof.
Costco Reward Certificates vs. Costco Cash Cards
Costco Reward Gift Certificates and Costco Cash cards are similar but not identical. Both never expire and both can be used at any Costco location or on Costco.com. The main difference is how they work at checkout: a certificate is a one-time document with a specific dollar amount, while a Costco Cash card is a reloadable card that tracks your balance electronically.
If you have a Costco Cash card, you can add money to it over time. A certificate, by contrast, is a fixed amount that you use until it runs out. Both are treated the same way in terms of expiration—neither one expires, and both can sit unused for as long as you need.
Certificates from Promotions and Rebates
Costco issues Reward Gift Certificates through various promotions, such as when you open a new membership, renew your membership, or receive a rebate on a returned item. All of these certificates follow the same rule: no expiration date. Whether the certificate came from a promotion, a rebate, or a gift, it works the same way and lasts indefinitely.
Some promotions may have terms that say you must use the certificate "within a certain period" to take advantage of a deal, but the certificate itself does not expire. The promotion may end, but the certificate remains valid for regular purchases.
Frequently Asked Questions
Can I transfer my Costco Reward Gift Certificate to someone else?
Yes, you can give the physical certificate to another person and they can use it at any Costco warehouse or on Costco.com. They do not need to be a member of your household or have any connection to your account. Once you hand over the certificate, it belongs to whoever holds it.
What happens if I use only part of my certificate?
The remaining balance stays on the certificate. You keep the certificate and bring it back on your next visit. There is no fee for holding it or using it in multiple transactions. You can use it as many times as you need until the balance reaches zero.
Can I get cash back if my certificate is worth more than my purchase?
No. Costco does not give cash back for Reward Gift Certificates. If your certificate is worth $50 and you spend $30, you keep the $20 balance on the certificate for future purchases. The unused amount does not convert to cash or store credit.
What if my certificate was damaged or the number is unreadable?
Contact Costco Member Services with your membership number. They can look up the certificate in their system and either replace it or give you the number. You do not need the original certificate to prove ownership if it is linked to your membership account.
Do Costco Reward Gift Certificates work at Costco Gas Stations?
Costco Reward Gift Certificates can be used for most purchases at Costco, but they typically cannot be used at the gas station pumps. You can use them inside the warehouse for any merchandise, including items from the food court, but fuel purchases usually require a Costco Cash card or a credit card.
