Quarterly Performance for Single-Piece First-Class Mail® International
Mailpieces Delivered Between 01/01/2020 and 03/31/2020

Overview

Single-Piece First-Class Mail International® Inbound and Outbound service performance is measured via the International Mail Measurement System (IMMS) operated by an outside entity. This system measures the length of time it takes for the domestic leg of transit for Single-Piece First-Class Mail International® letters and flats. Transit time for outbound mail begins when pieces are mailed from collection boxes or mail chutes, and ends when the pieces are sorted and ready to leave the designated international processing center in the United States. Similarly, transit time for inbound mail begins at arrival at the USPS® international processing center and ends with delivery to the intended recipient. It uses a rigorous external sampling system modeled after the External First-Class Mail® (EXFC) Measurement System. IMMS test mail letters and flats volumes are designed to be proportional to actual mail volumes by shape such that no weighting by shape is required in scoring calculations. Transit time is compared against First-Class Mail® service standards. On January 27, 2013, outbound Single-Piece First-Class Mail International® parcels became a competitive product and these data are no longer included in the measurement. Starting in FY2020 Quarter 2, inbound Single-Piece First-Class Mail International® parcels became a competitive product and these data are no longer included in the measurement.

Since not all postal administrative districts have sufficient international volumes for statistically representative reporting, the U.S. Postal Service® reports international quarterly service performance at a postal administrative area level.
