JSON
Open API
SOAP

Description

Checks a mobile telephone number for validity and returns some information about the subscriber.

If the telephone number is not supplied in full international format, the service will assume it is a UK number by default. This can be overridden by supplying an appropriate value for the DefaultCountryCode option.

This service is not appropriate if you require indication about any number other than a mobile number. In those circumstances, you should consider the use of the PhoneValidation service.

This service is deprecated in favour of the PhoneValidation service. This service will remain operational for the foreseeable future, but the PhoneValidation service should be used for all new development.

Note that cellphone numbers within North America are validated only to the extent provided by the international telephone validation service due to technical restrictions within the mobile network.

Credit Usage

Each request to this method consumes 1 MobileValidation credit.
