Quarterly Performance for Single-Piece First-Class Mail®
Mailpieces Delivered Between 04/01/2012 and 06/30/2012

Overview

Since 1990, the Postal Service™ has contracted with an outside entity to measure First-Class Mail® service performance independently and objectively via the External First-Class Mail® measurement system (EXFC). EXFC is a rigorous external sampling system measuring the time it takes from deposit of mail into a collection box or lobby chute until its delivery to a home or business. EXFC measures the transit time for single-piece rate First-Class cards, letters, and flat envelopes and compares this actual service against service standards. EXFC continuously tests service in 892 three-digit ZIP Code areas between which virtually all Single-Piece First-Class Mail® originates and destinates.

Service performance for Single-Piece First-Class Mail® parcels has been combined with EXFC performance to formulate these combined Single-Piece First-Class Mail® results. Single-Piece First-Class Mail® parcel service is measured using an internal USPS system. This system measures transit time from the time of mailing at a Post Office™ until the time of delivery for parcels for which a customer requested Delivery Confirmation™ service. Actual transit time is then compared against First-Class Mail® service standards.

Limitations

The USPS® Product Tracking System used to measure service performance for parcels with Delivery Confirmation™ did not fully account for 5-digit ZIP Code exceptions to the service standards for Alaska 3-digit ZIP Code area 995. As a result, some parcels sent to or from this ZIP Code area may have been measured against a service standard one day less than the actual service standard.
