How do I find the area code for a specific U.S. city?
Simply scroll through our city listings or use the search feature to find the city you’re looking for. Each city entry includes the area code(s) that correspond to that location.
Do some cities have multiple area codes?
Yes, larger cities or those in regions with high demand often have multiple area codes. This allows for a greater number of phone numbers within the same geographic area and helps accommodate growth in highly populated locations.
Why might a city’s area code change or gain additional codes?
Area codes are added or changed as cities grow and require more phone numbers. This often results in overlay codes or splits, where new area codes are introduced alongside existing ones to ensure adequate numbering for all residents and businesses.
