About Costco Wholesale

Costco is an American multinational chain of membership-only warehouse stores, as confirmed by its Wikidata record (Q715583). The company operates warehouse clubs where members can purchase a wide variety of goods in bulk quantities. Costco has expanded internationally with localized websites for major markets including Canada, the United Kingdom, Australia, and Mexico.

How to tell an official Costco page from a fake

Check the domain carefully. Official Costco sites use costco.com (US), costco.ca (Canada), costco.co.uk (UK), costco.com.au (Australia), and costco.com.mx (Mexico). Watch for misspellings or extra characters in the domain name.
Verify investor relations. Legitimate investor information is hosted at investor.costco.com. Fake sites often create fake investor pages on unrelated domains to appear credible.
Look for official social media handles. Costco's verified social accounts are @costco on Instagram and TikTok, @Costco on X (Twitter), Costco on Facebook, and company/costco on LinkedIn. Be cautious of accounts with slight variations in the handle.
Membership verification. Official Costco sites require membership for purchases. If a site offers Costco products without any membership requirement or login, it is likely fraudulent.
