Data8 Tele-Appending Service utilises BT OSIS and Data8 Business Universe.

The BT OSIS database provides you with access to over 27 million subscribers. We can match a name and address against the BT OSIS which will then provide a phone number associated with that person or company, creating a more wholesome record. 

Our own Data8 Business Universe also contains over 2 million business telephone numbers not found from any other provider.

Both data sources are updated daily to ensure the highest accuracy.

Avoid wasting precious time and resources and know that the number you're contacting will take you to the right person.
