CheckLoraAll 400-Series Area Codes
Browse the active area codes in the 400–499 range, with the city and state each one is primarily associated with. 32 codes listed.
An area code can span several cities or counties, so the location shown is the most representative one rather than the only place the code is used. Overlays mean two codes can serve the same region.
The code alone tells you the region, not who is calling. To find the name and public records behind a specific number, run a reverse phone lookup.
