The Postal Service offers free tools to track specific packages, but customers are required to either register online, or initiate a text message, and provide a tracking number. USPS does not charge for these services! USPS will not send customers text messages or e-mails without a customer first requesting the service with a tracking number, and it will NOT contain a link. So, if you did not initiate the tracking request for a specific package directly from USPS and it contains a link: don’t click the link!
