Service Standards

Service Standards were first published in January 2007 in accordance with requirements of the Postal Accountability and Enhancement Act of 2006. Service Standards are updated quarterly (January, April, July, October) to reflect changes in the processing, transportation, and delivery network.

Service Standards are officially defined as "A stated goal for service achievement for each mail class." A Service Standard represents the level of service that the USPS strives to provide to customers. These standards are considered to be one of the primary operational goals, or benchmark against which service performance is compared in various measurement systems.
