Mailing Services Measurement Results

The Postal Service™ measures service performance in terms of speed and reliability. Single-Piece First-Class Mail® includes letters, flats and parcels and is measured from collection box drop point to delivery. Presort First-Class Mail® includes commercial mail prepared by the mailers which is sorted to the finest extent required. Single-Piece First-Class Mail® International provides a measure of the domestic leg of travel for single-piece international mail.

USPS Marketing Mail™ is a class of mail consisting of mailable matter that is not required to be mailed as First-Class Mail or Periodicals. Service performance for Periodicals (e.g. publications) and Package Services, which includes Bound Printed Matter, Media Mail® and Library Mail is measured from entry into the postal system to delivery. Special Services measures those services purchased in addition to the required postage such as Registered Mail™, Certified Mail®, USPS Tracking™, and Signature Confirmation™. Other types of service such as the timeliness of Post Office Box mail “uptimes” or the electronic transmission of data such as Confirm® are also included in Special Services.
