Coplay, Cementon, Egypt, Fullerton, Hokendauqua and Stiles all share Whitehall Township’s 18052
\nZIP block along the Lehigh River — treat them as one postal cluster, not five separate
\ntowns, when mailing anything. Bethlehem straddles the Lehigh–Northampton county line; only
\nits western edge lies in Lehigh County, and the city’s government and downtown sit in Northampton
\nCounty.<\/p>\n
