Dayton has a post office with its own ZIP Code (08810) that encompasses the entire CDP, as well as some surrounding areas. The community was named for William L. Dayton, a local attorney who later served in the United States Senate, or for Jonathan Dayton, the youngest person to sign the United States Constitution, who later served as a U.S. senator from New Jersey. The area had been known as "Cross Roads" and was renamed in 1866 to avoid confusion with mail that was sent to another post office that shared the name.
