Veriphone saves you time and money

Veriphone's validation service has a fantastic ROI. Every invalid phone number removed from your lists is time saved for more profitable activities.


Outbound campaigns

Machines are not good at guessing. Feeding wrong numbers to auto-dialers and SMSing tools results in bad reach-rates and higher costs. By validating phone number lists on Veriphone, our users achieve better reach and lower cost.


Lead Scoring

A lead with a valid phone number has to score higher than a lead with a wrong number. Similarly, a mobile number may be worth more than a landline, while numbers from some countries may be worth more than others. Veriphone syncs with any lead scoring system to enable better scoring.



Veriphone will reliably append the country and region of any phone number. Which allows for automated dispatching of prospects over country or territory sales representatives. This automation reduces time to first contact, which in turn increases conversion rates.



Segmenting a marketing database is essential to creating timely and relevant messages. Veriphone provides extra parameters for segmenting any lead or customer database. Think country, region, carrier, and line-type.
