Quarterly Performance for Single-Piece First-Class Mail® International
Mailpieces Delivered Between 04/01/2018 and 06/30/2018

Quarter III
FY2018

Overview

Service performance for inbound and outbound Single-Piece First-Class Mail International® domestic transit is measured through the International Mail Measurement System (IMMS) operated by a third party vendor. IMMS utilizes only letter-shaped mail pieces, which is the predominant shape for both outbound and inbound Single-Piece First-Class Mail International®. IMMS uses an external sampling system modeled after and closely integrated with the External First-Class Mail® (EXFC) Measurement System used for domestic Single-Piece First-Class Mail®. Transit time is compared against First-Class Mail® service standards.

The processing of Single-Piece First-Class Mail International® flats and parcels -- during either outbound transit from domestic origin to designated International Service Centers (ISC) or inbound transit from designated ISC to the domestic delivery address -- is the same as for domestic Single-Piece First-Class Mail® Flats and Parcels. The USPS® service standards are also the same. Accordingly, the performance for domestic Single-Piece First-Class Mail® Flats (using the data from EXFC) and performance for domestic Single-Piece Parcels (as measured End-To-End on parcels for which customers have purchased USPS Tracking®) serve as proxies for the service performance of outbound and inbound Single-Piece First-Class Mail International® flats and inbound Single-Piece First-Class Mail International® parcels. On January 27, 2013, outbound Single-Piece First-Class Mail International® parcels became a competitive product and are no longer included in the score calculation.

The following service performance results combine the results for letter performance from IMMS with the proxy data to measure service performance for all inbound and outbound Single-Piece First-Class Mail International®. Since not all postal administrative districts have sufficient international volumes for statistically representative reporting, U.S. Postal Service® reports international quarterly service performance at a postal administrative area level.

Service performance measurement was suspended for mail originating from or destined to Caribbean District in FY 2018 Quarter 1 and FY 2018 Quarter 2 due to the devastating impacts of Hurricanes Irma and Maria. Measurement resumed in FY 2018 Quarter 3.
