The HLR Lookup Data Service is the best way to ensure your number lists are fully operational and the most effective they can be for messaging campaigns.

You can use HLR Lookup to clean number lists, find and remove all invalid numbers, or to obtain key information about the mobile subscriber.

Using the HLR Lookup service you will be able to source the following information:

  • If the mobile number is valid
  • The current network provider
  • If the number has been ported
  • If the number is inactive
  • If the number is roaming and which country the subscriber is currently located.

You can access this service by integrating with the HTTP HLR API.  Simply submit mobile numbers and select to receive the data either to a post back URL or a CSV file through email.
