Quarterly Performance for Single-Piece First-Class Mail® International
Mailpieces Delivered Between 04/01/2024 and 06/30/2024

Overview

Single-Piece First-Class Mail International® Inbound and Outbound service performance is measured via the USPS internal service performance measurement system. The service performance measurement system combines scanning of mailpieces by postal personnel at randomly selected collection and delivery points with in-process machine scans for all eligible mail to estimate total transit time for the mail. The total transit for outbound mail is comprised of two legs: collection to initial automated processing, known as First Mile; initial processing to final automated processing, known as Processing Duration. The final processing event for outbound pieces occurs once pieces are sorted and ready to leave the designated international processing center in the United States. Similarly, the total transit for inbound mail is comprised of two legs: initial processing upon arrival at the USPS® international processing center to final automated processing, known as Processing Duration; and final processing to delivery, known as Last Mile. Inbound flats are measured by proxy using the First Mile & Processing Duration performance of domestic flats. The estimated transit-time is compared against Single-Piece First-Class Mail® service standards to determine the percent of mail delivered on time. The service performance of inbound Single-Piece First-Class Mail International® parcels is measured by the USPS®, and represents the census data of all inbound parcels processed by the USPS®. 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.
