Got an email or text claiming to be from Costco about a free gift, survey reward, or account problem? It's almost certainly a scam. Real Costco rarely contacts customers this way, and they never ask you to click suspicious links or provide personal information via email.

The Costco Scam Epidemic
Costco is one of the most impersonated brands in phishing attacks. Why? Because 130+ million members trust the Costco name, making it perfect bait for scammers.
In 2025-2026, we've seen a massive surge in fake Costco messages promising:
- "Free" anniversary gifts or rewards
- Survey prizes ($100+ gift cards)
- Account verification requests
- Membership renewal notices
- Exclusive member deals
None of these are real. Let's break down exactly how to spot them.
Red Flags: How to Identify a Fake Costco Email
1. Check the Sender's Email Address
This is the #1 giveaway. Real Costco emails come from:
@costco.com@costcophoto.com@costcotravel.com
Scam emails come from addresses like:
costco-rewards@gmail.comsupport@c0stc0-members.com(note the zeros)costco.deals@randomdomain.netnoreply@costco.survey-winner.com
Pro tip: Scammers use "homoglyphs" - characters that look similar but aren't. Watch for:
c0stc0(zeros instead of o's)cรธstco(special characters)costco-followed by random words
2. Look for Urgency Tactics
Scam messages create panic:
- "Act within 24 hours or lose your reward!"
- "Your account will be suspended!"
- "Limited time offer - only 50 remaining!"
- "URGENT: Verify your membership now!"
Real Costco doesn't threaten you. If your membership actually had an issue, they'd handle it calmly at the warehouse.
3. Too Good to Be True Offers
Common fake offers:
- "You've won a $500 Costco gift card!"
- "Free Costco cooler for completing a survey"
- "Anniversary special: Free products for members"
- "Claim your $100 reward for being a loyal customer"
Reality check: When was the last time any company gave you $500 for clicking a link? Costco's actual promotions are in-store or through their official app - not random emails.
4. Suspicious Links
Hover over (don't click!) any links in the email. They should go to:
costco.comcostco.com/...
Scam links go to:
costco-rewards-claim.comsurvey.costco-member-gift.netbit.ly/costco-offer(shortened URLs)costco.com.fake-domain.com(subdomain tricks)
5. Poor Grammar and Formatting
Many scam emails have:
- Spelling mistakes ("Costoco", "recieve")
- Awkward phrasing
- Mismatched fonts
- Low-quality logos
- Generic greetings ("Dear Customer" instead of your name)
However, some sophisticated scams are well-written - don't rely on this alone.
6. Requests for Personal Information
Costco will never ask via email for:
- Your full credit card number
- Social Security number
- Account password
- Bank account details
- Gift card numbers as "payment"
If an email asks for any of these, it's 100% a scam.

Why Scammers Love Impersonating Costco
Costco is the perfect target because:
- Massive member base - 130+ million potential victims
- Trusted brand - members are loyal and let their guard down
- Expectation of deals - Costco is known for great offers, so fake deals seem plausible
- Renewal cycles - members expect periodic communication about memberships
- High-value purchases - members have money to steal
Protect Yourself: Quick Checklist
Before clicking anything in a Costco email:
- Is the sender's email from
@costco.com? - Does the link actually go to
costco.com? - Is the offer realistic (not free hundreds of dollars)?
- Is there pressure to act immediately?
- Can you verify this offer on Costco's official site?
If you answered "no" to any of these - it's probably a scam.

FAQs
Does Costco send promotional emails?
Yes, but only if you opted in. Real promotional emails come from @costco.com and don't ask for personal information or include urgent threats.
Can I win a Costco gift card via email?
Costco occasionally runs legitimate contests, but winners are contacted through verified channels, not random emails. If you didn't enter a contest, you didn't win one.
What if the email has my name in it?
Scammers often buy leaked data that includes names. Personalization doesn't make an email legitimate.
Are Costco text messages real?
Costco may send texts for pharmacy, optical, or order updates if you opted in. Random texts about rewards or gifts are scams.
How do I know if my Costco account was compromised?
Log into Costco.com directly (don't click email links) and check your order history and account settings. Change your password if anything looks suspicious.
Stay Safe
Scammers are getting more sophisticated, but the fundamentals haven't changed: real companies don't ask for sensitive information via email, and free money doesn't exist.
When in doubt, verify directly with Costco or run the message through our free scam checker.
Stay vigilant. Stay safe.
