How does it work?

Carrier lookup tools use data sourced from local exchange routing guides (LERG), telecom registries, and national number portability databases to identify the current network provider of a given phone number. They can also confirm whether a phone number is a wireless/cellular, landline, virtual line (VOIP), or pager. Some even determine the country where the number is registered and if it has been ported from one network to another.
