Telephone Number Validation

Although dialing codes changed in the UK many years ago, many databases continue to use old codes. It is important to check your telephone numbers against a file containing the current numbers.

The Database Manager will check standard dialing codes inserting appropriate spacing to suit current dialing systems. We also accommodate mobile, premium rate and freephone codes.

Telephone numbers change every day

We can take your database and verify that all telephone numbers are accurate. This is a very important cleaning activity, after all 50,000 numbers change in the UK every day!

Where you have no telephone numbers on your list we can automatically apply a correct telephone number to your list.

Telephone preference service

We check all telephone numbers against the telephone preference service to make sure you are allowed to use the numbers.
