The OIG has issued a series of reports on the Postal Service’s universal service obligation (USO).
As we discuss in the 2014 Guiding Principles for a New Universal Service Obligation report, unlike many other posts, the Postal Service does not have a precise definition of its USO
Instead, the USO is generally agreed to be made up of a collection of laws and regulations that sometimes provide only broad guidance.
There are, however, some aspects that are clearly defined, such as the requirement to deliver mail six days a week.
