How Do You Benefit from Phone Number Validation?

Are all the numbers in your database existing, in the right format and available? By verifying the numbers in your database, you can run more effective campaigns. This means campaigns with better reach, bigger response, lower undelivered rates and high-cost effectiveness.

Optimise the routing or use phone number validation to clean up a database of numbers to improve the accuracy of your batches. Also, you'll avoid problems caused by mobile number portability (MNP) and roaming delivery issues.

This solution for number validation is easy to use and can be implemented in any existing system with our API.

Technical Documentation

With CM's phone number validation & number lookup API, you can validate any phone number. It will tell you the formatting options and number type, as well as the most likely carrier.

Also, you can generate additional information for phone numbers in your database. This contains information like formatting options, the actual operator, if the number is roaming and even if the number is active on the network.
