How does it work
The phone verification service performs 3 checks when a phone number is sent to be validated.
- Range checks: Checks number length and range to identify the phone's country of connection and line type.
- Connection checks: Verifies if the phone number is active by performing a flash-call. This makes sure that the phone number is real and accepts incoming calls and texts.
- Rules checks: Verifies if the phone number matches your filter settings. For example, only allowing landlines.
