What does the abbreviation “USPS” stand for?

The abbreviation “USPS” stands for "United States Postal Service." This is the official name of the agency responsible for providing postal service in the United States. The USPS operates as an independent establishment of the executive branch of the U.S. government, and its main function is to ensure reliable and affordable mail delivery to all residents and businesses across the country.

Understanding this term is essential, especially for those preparing for postal service roles or related qualifications, as it encompasses the agency's identity and mission in facilitating communication and commerce through mail and package delivery. The other options do not represent the official title of the United States Postal Service, highlighting the importance of recognizing correct and widely accepted terminology in the context of postal operations.
