06858 ZIP Code
English Español
ZIP code 06858 covers Norwalk, Connecticut. It has no Census ZIP Code Tabulation Area, which is how the Census Bureau treats ZIP codes that are not residential neighbourhoods — PO box-only ranges, military addresses, and codes assigned to a single large organisation. There are no population or income figures for it because nobody is counted as living there.
