how long will a letter take usps
Priority Mail Delivery Times. _Priority Mail_ is a USPS service for delivering mail that weighs between 13 ounces and 70 pounds, which has been marked as important by the sender, so that the carrier attempts to deliver it as quickly as possible. This generally takes between one to three days. The USPS website displays a map of the various mailing districts. When someone punches in their ZIP Code of origin, the map shows whether it would take the mail one day, two days or three days to arrive in that district.
