Since North Wantagh does not have a post office of its own, all places in the hamlet have either a "Wantagh, NY 11793" or "Seaford, NY 11783" mailing address. Non-conforming postal codes lead to a general misconception of the actual boundaries of this, and surrounding, areas. Parts of North Wantagh are more commonly referred to as simply "Wantagh" or "Seaford," while school service is provided by Levittown.
