What to Do If You Lost Your Costco Rewards Check

Every February, Costco Anywhere Visa cardholders receive an annual reward certificate — a printed check bundled with their membership renewal notice. For most people, it's a pleasant surprise. For others, it becomes a source of stress when that check goes missing before it can be redeemed.

The good news: a lost Costco rewards check isn't necessarily gone forever. But the process for recovering it has some real constraints worth understanding before you assume it's a simple fix.

What Is the Costco Rewards Check, Exactly?

The Costco Anywhere Visa card, issued by Citi, earns cash back on purchases throughout the year. Rather than crediting rewards monthly, Citi consolidates the full year's earnings into a single annual reward certificate, mailed once per year — typically in February — alongside your Costco membership renewal documents.

That certificate functions like a check. You can:

• Redeem it for cash at any Costco warehouse
• Use it as store credit toward purchases in the warehouse

The catch: it can only be redeemed at a physical Costco location. You cannot redeem it online, by mail, or over the phone. And there's an expiration date — the certificate is valid for a limited window, typically tied to the calendar year in which it's issued.

Why Losing It Is More Complicated Than It Sounds

Because the certificate is a physical document — not a digital balance — losing it puts you in a similar position to losing a paper check. The funds are tracked by Citi, but accessing them requires navigating both Citi (the card issuer) and Costco (the membership organization), which don't always operate as a seamless unit from the cardholder's perspective.

There's also a timing element. If you realize the check is missing shortly after it was mailed, your options are different than if months have passed.

📞 Step One: Contact Citi Directly

Your first call should be to Citi customer service, the number on the back of your Costco Anywhere Visa card. This is the issuing bank and the entity that controls your rewards balance.

When you call, ask specifically about:

• Confirming your current rewards balance — what amount was on the certificate
• Whether a replacement certificate can be issued — Citi does have the ability to reissue in some cases
• Whether the original certificate has been redeemed already — if someone else cashed it, that's a separate fraud issue

Be prepared for the process to take time. A replacement isn't instant, and Citi may require you to confirm identity, verify your mailing address, and wait a processing period before a new certificate is sent.

Step Two: Understand the Costco Side of the Equation

Costco warehouses themselves have some visibility into member accounts, but their ability to help with a lost reward certificate is limited compared to what Citi can do. Member services at your local warehouse can sometimes look up certificate status and confirm whether it's been redeemed — but they typically can't issue a replacement on the spot.

What Costco can do:

If you've already spoken to Citi and have a case number or replacement in progress, bringing that documentation to the warehouse membership desk can sometimes help move things along — especially if you need to redeem before an expiration date.

⏳ Expiration Dates Matter More Than Most People Realize

The annual reward certificate has an expiration date printed on it. If your certificate has expired — or is close to expiring — your options narrow.

Citi's policy on expired certificates is not universally forgiving. In some cases they will honor a replacement request even after expiration, particularly if the loss was documented early. In others, the funds may be forfeited.

The key variable here is timing. The sooner you contact Citi after realizing the certificate is missing, the more options you're likely to have. Waiting until November to report a February certificate as lost is a very different situation than calling in March.

If the Certificate Was Stolen or Cashed Fraudulently

If you believe the certificate was stolen from your mailbox or redeemed by someone other than you, treat this as a fraud issue, not just a lost document. Citi has fraud resolution processes that may apply here. Document everything — when you received (or expected to receive) the mailing, when you noticed it missing, and any evidence of unauthorized redemption.

What Affects Your Outcome 🔍

Not every lost certificate situation resolves the same way. Several factors shape what's actually recoverable:

• How much time has passed since the certificate was issued
• Whether the certificate has already been redeemed by someone else
• Whether the expiration date has passed
• Your account standing with both Citi and Costco
• How clearly you can document the loss (e.g., you moved, the mail was misdelivered, you recently changed addresses on file)

An updated mailing address on your Citi account is often the silent culprit behind missing certificates. If your address wasn't current when the certificate was mailed, that's worth confirming before assuming the check was simply lost in transit.

The steps above give you a clear path forward — but whether a replacement is issued, and under what conditions, comes down to the specifics of your account, your timing, and the details Citi finds when they look into your case.
