Why do I receive mail that shows my city as Trenton instead of Hamilton?
While residents can place "Hamilton" along with the proper zip code on mail, the United States Post Office officially considers it "Trenton." Although most of us probably go by municipal boundaries, unfortunately Postal Zip Codes do not. In fact, former Mayor Rafferty unsuccessfully attempted to get the Post Office to change this is the past.
Therefore, what can typically occur for businesses or organizations using lists of our residents, is the lists will have what the United States Post Office officially goes by, "Trenton."
