TPL Media’s telephone number verification service helps clients avoid unnecessary costs and wasted effort making calls or sending SMS messages to invalid numbers. In a sales or customer service process, this means fast and efficient communications at every stage.

The Home Location Register (HLR) is the main database of permanent subscriber information for a mobile network. HLR Lookup is a service that dynamically contacts this database to check for active and inactive numbers, and if the mobile is switched on. HLR Lookup can also be used to identify the home network of a mobile number.

The Landline Verification (LLV) service is a test to identify the status of a landline telephone number without dialling the number. This means no silent or abandoned calls; numbers are checked automatically without disturbing the household. The service checks if a number is working or if it does not connect.
