United States Postal Service

The United States Postal Service (USPS) is an independent agency of the federal government responsible for delivering mail and packages to every address in America. Operating under a universal service obligation, USPS is the only delivery service with a legal mandate to reach nearly 169 million residences, businesses, and post office boxes nationwide, regardless of location or profitability. Unlike private carriers, USPS receives no tax dollars for operations and relies on postage sales and services to fund its work.

Sending Mail and Packages

Whether sending a letter or package, start with basics like how many stamps you need or weight and size limits. USPS handles specialized needs, from plants and musical instruments to military addresses. Always check the prohibited items list and hazardous materials rules. Businesses can save with bulk mail services.

Tracking and Delivery

USPS offers tracking numbers to monitor shipments. Learn common tracking statuses to know what to expect.
