WASHINGTON — From the busiest cities to the most remote locations, the U.S. Postal Service has been delivering mail and connecting the nation for 250 years.
Throughout its history, the Postal Service has used various forms of transportation to ensure customers receive their mail and packages. Some delivery routes are served by more traditional means — vehicles and walking — while others are served by less conventional methods such as dog sleds, boats, donkeys, and bicycles. No matter the transportation choice, the delivery routes all have one thing in common: dedicated mail carriers.
Postal Geography
What began as a handful of routes crisscrossing the United States has grown into a network of more than 234,000 delivery routes encompassing all 50 states, the District of Columbia and the five major U.S. territories — Puerto Rico, U.S. Virgin Islands, Guam, Northern Mariana Islands and American Samoa.
To operate more efficiently, the Postal Service organized the nation into four geographic regions — Atlantic, Central, Southern (including Puerto Rico and the U.S. Virgin Islands), and WestPac (Western and Pacific states as well as Guam, Northern Mariana Islands and American Samoa). The states and territories within the four regions are divided into 50 districts. Some states are combined to form one district (for example, Kentucky-West Virginia) while other states are divided into multiple districts (such as California, which has six districts).
