The Validate Single Number method allows you to check the validity of a phone number and whether the handset is currently on or off. You can also discover details about the network the phone number is on and whether the phone is outside its native country.
It makes a HLR request to the mobile networks to discover information about the phone number and its current status. HLR is widely supported globally but the amount of information returned can vary by country and network. Please see our HLR coverage table here for more details about coverage in specific countries.
The status returned will be one of the following:
The number exists and the handset is currently switched on.
The number exists, but the handset is currently switched off or out of range.
The number does not exist.
The number exists, but is not owned by a mobile network, for example a landline number.
The number does not conform to a recognised pattern or contains non numeric characters.
The number is not in a format that matches the requested country code.
A username supplied to ValidateNumberForUserNames is not recognised.
