A fake USPS tracking number is one that doesn’t match any actual shipment. Scammers sometimes use these to make it look like a package has been sent when it hasn’t. In other cases, people might reuse old numbers that no longer reflect active deliveries. If you enter a number on a tracking site and nothing shows up, or it’s stuck with no updates, there’s a chance it’s fake.
This article explains how to spot a fake USPS tracking number, what it looks like, how to handle suspicious deliveries, and where to report fraud.
