United States Postal Service (USPS) providing its service from very long time and still continues to be serving its customers from all over the world. People of US send or receive the mails using USPS services or mail class. It may happen sometimes that package doesn’t reach on given time on given address in that situation people start tracking their packages but after delivery then you find that it is not that package that you are waiting for then you can return the package in that case to the sender.
As above I told you that you can return or refuse a mail, package or shipment but the question arises how you will do the same thing so to know read the article below.
Package delivery can be refused during the delivery and even after delivery also. If you haven’t received the package then ask the post carrier to send it back on the original address and if you have received the package wrongly means that package doesn’t belong to you then you can simply write “Refused” on the letter or package and put it in a mailbox again and tell the post carrier to pick up the mail from the mailbox. This way seems to be easiest way of refusing but remember don’t open the mail they may be an important one. You may also get mails on weekends i.e. Saturday and Sunday.
