Reduce costs by cleaning up mobile number lists with CardBoardFish Number Validation.

Number validation provides a complete solution to the problem of poor quality mobile number lists and the need to identify ported numbers in a number database. This tool identifies invalid numbers, numbers which are experiencing a temporary problem preventing them from receiving SMS, and can also determine whether a number has been ported to another network.

Standard Number Validation:

A network query examining the Home Location Register (HLR) will be performed and the status of each number will be returned. If the status is anything other than "Success" then an error code and error description will also be returned. Numbers with a "Success" status will also be assigned their MCCMNC (MCC and MNC codes), identifying the country and network they currently reside upon.

Advanced Number Validation:

Same as above, but also shows the operator name and whether the number is ported. If the supplied mobile number (IMSI) is ported, both the original and current network names are displayed. The Advanced service is available on request and at extra charge.

Pricing:

Existing Large SMS account customers can log in to their account and add the Number Validation (HLR Lookup) service to their account instantly with no set up fees.
