If you're suspicious about an email that claims to be from eBay, sign in to My eBay and click the Messages tab. If you don't see the same message there, the email is fake. To report a fake email, forward it to email@example.com.
Concerned about a fraudulent listing? At the bottom of every listing you will find a link saying "Report this item". That takes you to a form you need to fill in to tell us why you are reporting. This includes counterfeit or stolen items, or other suspected fraud.
