HLR Lookup

HLR Lookup

Mobile Number Portability (MNP) has increased in popularity - this allows mobile phone users to change to an alternative network, but retain their original number.

With many changing network and mobile number so as to get the most recent handset this presents an increasingly difficult challenge to guarantee the successful delivery of text messages.

World Text's HLR Lookup service allows you to check the validity of a mobile number, reducing your costs spent on undeliverable messages due invalid or out of date information.

Who and for what should HLR Lookup used for?

  • Financial Organisations
  • Marketing Organisations
  • Contact Centres
  • Emergency Rescue Callout
  • ID Validation for Fraud Prevention
  • Mission Critical Responders
  • Any Contact Database
  • Call termination

Key benefits

  • Save Money - No more sending messages to invalid numbers
  • Cleans Database - Prompt for contacting client or colleague for updated details
