area_code_lookup
shallowcom.codepostalpro/postal-codes · Verify this server
Where a US telephone area code is used: the state(s) it serves, the cities with the most ZIPs listing it, total ZIP and city counts, and `overlay_codes` — codes assigned to the same territory (e.g. 310 and 424 in west Los Angeles). Use it for "where is area code 310", "what area code is Denver" (via the city’s ZIPs instead), or to sanity-check a phone number’s geography. Caveat to relay: NANPA assigns codes to rate centres, matched here to cities — city-level accuracy, not a legal boundary, and a mobile number keeps its code when its owner moves.
