PRODUCT USE CASES

Phone Number Validation Is Essential

Refine Leads Database

Companies running SMS based marketing promotions against leads database imported from different sources often report significant number of invalid and non existent contact numbers. Verification of phone numbers helps in cleaning up this database without sending real messages and increases chances of conversions with accurate lists.

Save On OTP Check

Almost all online applications connect to messaging providers for one time password based validation of their user’s contact numbers.

By performing a phone number validation before OTP check can help you save significantly on such charges for all non existent and invalid contact numbers.
