In case anyone didn't know, USPS has a system called informed delivery which allows you to centralize all tracking for any and all packages AND mail that is coming to your house. They scan everything at all points in transit and you can get images of bills, letters and even magazines and stuff that will hit your mailbox or doorstep a week before it does. Its really helpful if you have packages coming from different companies or purchase platforms like amazon or aliexpress or whatever else, all the tracking ends up in this system and its a single easy webpage to keep track of stuff.
