Before you mindlessly click on that text message that looks like it's from FedEx, take a second look because it could be a scam.

Most importantly, FedEx tracking numbers are all 12 (for FedEx Express) or 15 digits (for FedEx Ground) long, as opposed to the 10-digit codes seen in texts from people hit by the scam.

The New Jersey governor has proposed tracking immigrants because "If FedEx can do it, why can't we use the same technology to do it?" The technology FedEx uses is based on bar-code scanning.

Just send a DM (not a @reply) with the FedEx/UPS/USPS/DHL tracking code first, followed by a nickname for the package. Click here to send your message. Example: 123456789123 Macbook Air 3.
