Telephone Number Appending

Accurate, up-to-date telephone numbers will help you follow up your mailing campaign and provide you with the power to communicate quickly and efficiently with your customers and make it easier to implement telemarketing campaigns.  The Mailing Expert Telephone Number Appending service matches customers against the BT OSIS Database and can append up to 3 telephone numbers per household.  The BT OSIS Database has over 27 million subscribers.  There are around 50,000 changes to the database every week.  We can also flag up customers that are ex-directory (indicating that a line is active at the address), however we are not able to supply ex-directory numbers themselves.
