The first post office in Hannaford was established November 17, 1886, with R. C. Brophy the first postmaster. Prior to this time, postal service was available at the Montclair Post Office. The first post offices were located in the place of business of whomever was postmaster at the time. Mr. Brophy was postmaster until February 13, 1889, when E. H. Groven was appointed. He was followed by Archibald Sinclair in 1895, Claus Jackson in 1899, Christian Reite in 1913, Wm. D. Sinclair in 1919, George Knauss in 1936, Fred Knauss in 1951, and Jeanette Richardson Arbuckle in 1974. The post office was located in the old bank building which is now Ray's Barber Shop from 1936 until 1959. When Security State Bank built their new bank building in 1959, the post office moved into the old bank building and remains there in 1976.
Two rural free delivery routes were established out of Hannaford on November 1, 1905. The carriers were to leave Hannaford every day at 10:30 a.m., and return no later than 6:30 p.m. Their salaries were $750 per year. A. M. Sinclair was the first mail carrier going east and his route covered 29 miles and 106 houses. Lars Alm had the route going west and this was 31 miles long with 104 houses. Johnny Haugen took A. M. Sinclair's route in 1906. L. A. McCallson started as a mail carrier in 1909, and retired in 1943. In 1924, a third route was added, but was discontinued in 1943. Other carriers during the years have been Harry Richardson and Carl Heyerdahl. Homer Benson has been carrying mail since 1946. When Heyerdahl retired in 1966, the two routes were combined into one. The Revere Post Office was closed in 1954, and the Walum Post Office in 1973. Both areas are served by the Hannaford carrier.
Today the one rural route covers 132 miles, serves 161 families and there are 156 boxes, 21 of which are right in Hannaford.
