Early mail service in Wheeler County was established at Fort Elliott. In 1879, a U.S. post office opened in the town of Mobeetie, previously known as Sweetwater. George A. Montgomery served as the first postmaster. In 1928, after the town moved one-mile north to this present site on the Santa Fe railroad line, a new post office was built. Rural mail routes were expanded in the 1930s to serve the increasing numbers of farm families, but decreased in later years after drought and harsh conditions led to the abandonment of some farms.
