Mobile Number Validation (HLR Check/HLR Lookup)

Mobile phone

HLR Checking / HLR Lookup is ideal for:

  • Sales & Marketing professionals
  • SMS Marketing
  • Telemarketing/Call Centres
  • Mobile Phone Upgrade Providers

How does it work?

Mobile number validation is a cost effective method of finding information about any mobile number on the GSM (Global System for Mobile Communications) network. The process uses a Home Location Register (HLR) Lookup on each number which tells us the following information (download sample results file):

  • Phone Status (Live or Dead)
  • Current Network Provider
  • Original Network
  • Country Roaming (if abroad)

With the rise in mobile phone use, mobile marketing has emerged as an important channel in the marketing mix. Whether contacting customers by phone or via sms, it is important to ensure your mobile database is kept clean.

Key benefits of HLR Checking

  • Reduce wasted operator time calling dead or invalid numbers
  • Save costs on SMS marketing
  • Improve campaign efficiency

SMS Cost Savings

The table below shows the cost savings achievable based on a 20% dead/invalid rate. Mobile databases typically decay by around 20% per annum. Larger savings can be achieved with multiple campaigns or with high dead/invalid rates.
