Areas within Amherst are referred to by the former post office station names and are not legally incorporated. During the 1990s, many of these regional post offices were closed and consolidated into the central Amherst 14226 post office on Bailey Avenue, leaving only a Williamsville (14221) post office on Sheridan Drive, a Getzville (14068) post office on Millersport Highway, and an East Amherst (14051) post office on Transit Road. Mailing addresses to areas within the town are Amherst, East Amherst, Eggertsville, Getzville, Snyder, and Williamsville. These postal districts are still recognized by the post office and widely referred to by citizens.
