Number Lookup


Number Lookup is also known as HLR Lookup, Network Query or MNP Check. This 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 Network Query is necessary.

Number Lookup helps in optimization of SMS and voice routing and avoids cost and effort of messages returned due to Mobile Number Portability (MNP) by identifying invalid or unused numbers.
