Phone Validation FAQs

What is phone validation?

Widely used across a range of industries, phone verification is used to confirm that the number provided by your client or customer is valid and available. It can also serve as an additional way to verify the client’s identity – think Google’s two-step verification process, which uses your phone number to confirm your logins.

By ensuring customer details are real and valid, phone validation ensures higher ROI on marketing campaigns, better communications (and improved customer experience), and quickly ensures regulatory compliance.
