About USPS®

USPS or the United States Post Service is an independent agency of the US government that provides postal services in the United States. In 2013, it had over 200,000 vehicles and as of January 2014, it has more than 600,000 workers.

USPS operates the largest civilian fleet all over the world and is legally bound to serve all Americans regardless of geography at the same price and quality of services.

Aside from having access to letter boxes marked with U.S. mail and personal letter boxes in the U.S., USPS partners with the Department of Defense in operating a postal system in delivering mails for the military; known as the Army Post Office (for the Army and Air Force) and the Fleet Post Office ( for Navy, Marine Corps and Coast Guard).

Expanded Tracking Service also supports over a hundred additional regional and international carriers. Many of the additional carriers you are probably familiar with - and some you may not recognize. Some of those names include DHL®, DPD, China Post, Australia Post, Aramex, Swiss Post, Royal Mail and much more.
