Question: are any zip codes in multiple states?
Answer: 8 Answers. There are 13 multi-state US Census' ZIP Code Tabulation Areas (ZCTAs): 02861, 42223, 59221, 63673, 71749, 73949, 81137, 84536, 86044, 86515, 88063, 89439 & 97635. ... So your example of 42223 does span a state border, but it looks like it is actually between Maryland and Virginia.
