Morphology
united + state + post + office
The meaning is directly and transparently derived from the constituents: 'United States' denotes the country and 'post office' denotes the agency/place that handles mail, so together they refer to the U.S. postal service/place. This is a standard, compositional naming pattern found cross-linguistically and requires no idiomatic knowledge, so a B1 learner who knows the words would understand it.
Etymology
United States Post Office gets its name from old mail posts, fixed places where messengers stopped, and from an office that managed those stops. When the U.S. government created one national service to send and receive letters across the country, the name came to mean the government service that 'delivers mail'.
