Phone number verification | Voice and SMS Broadcast | CallHub

Analyse your phonebook before you start your campaign

Keeping data clean and accurate is hard. Our phonebook analysis service lets you analyse entire phonebooks and weed out the bad numbers. You can then decide to either correct the phone number or remove it from your phonebook. This gives you a lot of flexibility.

We recommend that you verify the contacts in your phonebook early so that you have time to correct any numbers that are invalid. Your voice or SMS campaign will then have a higher success rate.
