Phone Validation

Accurate data allows your organisation to maintain contact and relationships with customers. If the contact details in your contact database have errors, communications fail. AFD’s phone validation solution helps ensure the number entered is not only formatted correctly and has the right number of digits, we also check the number is “live”.

Phone Validation

Making the right call (or text!)

AFD Software's new phone validation feature can greatly reduce the number of errors (or invalid phone numbers) entered into your organisation's records. You will have much more confidence in your data and customers will receive the communications you intended!

Just one incorrect digit can lead to your customer missing essential communications, order confirmations, delivery updates, appointment reminders and special offers.

AFD's Telephone Validation solution validates UK landline, UK mobile and International telephone numbers at the point of entry. In addition, it shows whether the telephone number is currently "live" where possible (but note that it does not verify that the number is correctly associated with a named individual or organisation).

GDPR Compliance

GDPR (article 5.1) requires that "Personal data shall be: (d) accurate and, where necessary, kept up to date". AFD’s new service can help you meet the obligation to enter and maintain accurate, reliable information.
