Millerton was the original county seat of Fresno County, that was formed in 1856 when the county was larger than today. The county comprised its current area and all of what became Madera County and parts of what are today San Benito, Tulare, Kings, Inyo, and Mono counties. Two years after the station was established, in 1874, county residents voted to move the county seat from Millerton to Fresno. The vote totals were Fresno 417; Lisbon 124; Centerville 123; Millerton 93. Millerton was eventually abandoned as a result. The ZIP Code is 93623. The community is inside area code 559.
