Number Lookup

The Infobip Number Lookup service identifies which network a particular mobile phone number belongs to, as well as provides an existence check for every MSISDN queried. If a particular country has implemented Mobile Number Portability (MNP), then this procedure, also known as network query or MNP check, is necessary.

Number Lookup helps you optimize SMS and voice routing and avoid cost and effort of messages returned or calls failed due to MNP by identifying invalid or unused numbers. It can be also used in SMS banking or SMS marketing operations to determine the availability of end recipients, and as a way to clean mobile number databases.
