Foundation On August 28, 1907,
James E. Casey founded the American Messenger Company with Claude Ryan in
Seattle, Washington, capitalized with $100 in debt. Most deliveries at this time were made on foot and bicycles were used for longer trips. The American Messenger Company focused primarily on package delivery to retail stores with special delivery mail delivered for its largest client, the
United States Post Office Department—the predecessor of today's
United States Postal Service. In 1913, the company acquired a
Ford Model T as its first delivery vehicle. Casey and Ryan merged with a competitor, Evert McCabe, and formed
Merchants Parcel Delivery. Consolidated delivery was also introduced, combining packages addressed to a certain neighborhood onto one delivery vehicle. The
common carrier service was acquired in 1922 from a company in Los Angeles, California. UPS became one of the only companies in the United States to offer common carrier service. At first, common carrier was only limited to a small area around Los Angeles but by 1927 expanded to areas up to 125 miles outside the city. In 1924, a conveyor belt system was debuted for the handling of packages for UPS operations. The use of a common carrier for delivery between all customers placed UPS in direct competition with USPS, and delivering parcels beyond the California border brought it under the jurisdiction of the
Interstate Commerce Commission. The first city for UPS to use common carrier status outside California was Chicago, Illinois, in 1953. UPS delivery vehicle in 1921 Air service through UPS was first used in 1929 through private airlines. However, the
Great Depression and a lack of volume ended the service. In 1953, UPS resumed air service called UPS Blue Label Air with two-day service to major cities along the
East Coast and
West Coast.

Greenwich, Connecticut, and began serving all of the 48
contiguous states of the United States. This expansion of operations made UPS the first package delivery company to serve every address in the contiguous United States.

UPS Next Day Air Service was launched in 1985 for all 48 contiguous states plus Puerto Rico. In 1988,
