The Domestic Mail Service Standards Web Tools provide information as to the delivery times for three separate services: Priority Mail, Package Services (including the four types: Parcel Post, Bound Printed Matter, Library Mail, and Media Mail), and Express Mail Service. For Priority Mail and Package Services, the applicable Web Tool calculates the average number of days it will take for a package to arrive at a destination ZIP code from its origination ZIP code. The Express Mail Service Web Tool provides an exact delivery date for that service.
