Landline Cleansing

Make sure you don't call dead or invalid numbers

Landline Validation Identifies Dead and Invalid Numbers


The landline number validation service is ideal for call centres, list owners and data brokers. When you validate a number, you identify its present status and whether it is connected and contactable. It also ensures your list does not contain inactive numbers so you no longer have to waist time calling them and incur potential unnecessary charges.
