Package delivery or parcel delivery is the delivery of shipping containers, parcels, or high value mail as single shipments. The service is provided by most postal systems, express mail, private package delivery services, and less than truckload shipping carriers.
In 1852 Wells Fargo, then just one of many such services, was formed to provide both banking and express services. These went hand-in-hand, as the handling of California gold and other financial matters required a secure method for transporting them across the country. This put Wells Fargo securely in the stagecoach business and prompted them to participate in the Pony Express venture. They were preceded, among others, by the Butterfield Overland Stage, but the failure of the latter put the business in Wells Fargo's hands and led to a monopoly on overland traffic that lasted until 1869, when the transcontinental rail line was completed. During this period they carried regular mail in addition to the package business, defying the post office monopoly; eventually a compromise was worked out wherein Wells Fargo charged its own fee on top of federal postage, in recognition of the limitations of the post office reaching all areas easily.
From 1869 on, package services rapidly moved to rail, which was faster and cheaper. The express office was a universal feature of the staffed railroad station. Packages traveled as "head end" traffic in passenger trains. In 1918 the formation of the United States Railroad Administration resulted in a consolidation of all such services into a single agency, which after the war continued as the Railway Express Agency (REA).
On January 1, 1913, parcel post service began, providing rural postal customers with package service along with their regular mail and obviating a trip to a town substantial enough to support an express office. This, along with Rural Free Delivery, fueled a huge rise in catalog sales. By this time the post office monopoly on mail was effectively enforced, and Wells Fargo had exited the business in favor of its banking enterprises.
