Bangall has a post office with ZIP code 12506, which opened on August 8, 1851. Bangall lies in the Town of Stanford, which was created from the Town of Washington in 1793. According to local lore, the hamlet's name derives from a Yankee tinker passing through the settlement who was harassed by some youths who went so far as to strike the tinker's horse in the head, killing it. To this the tinker is supposed to have responded, "Well, this does bang all!" A phrase that circulated until it stuck.
