The United States Postal Service (USPS) is the only organization in the country that regularly delivers to every residential and business address. USPS is committed to providing secure, reliable, and affordable delivery of mail and packages to more than 157 million addresses in the United States, its territories, and its military bases worldwide. Processing and delivering 47 percent of the world's mail, USPS manages over 30,000 retail locations and constantly innovates to make customer experiences better. Customers have praised the friendly and knowledgeable employees who go above and beyond to provide excellent service. The shipping process is described as very quick, easy, and affordable, with packages being delivered to the right destination very quickly and without any damage. However, some customers have noted that the mail sorters or processors sometimes fail to place packages in the correct mailboxes, requiring them to get in line and ask the clerk for assistance.
