Data Source

Area-code data is imported from Area Code Geolocation Database, a North American area-code geolocation database. GitHub.

This is a snapshot of an external open dataset, not a live telecom feed. Area-code boundaries and city associations may change over time, and number portability means an individual number may not be located where its area code suggests. Always confirm details with the relevant carrier or authority before relying on them.

Portability note: numbers can be moved between providers and regions, so an area code does not guarantee the caller's actual location.
