Add or amend telephone numbers on customer records by screening against the BT subscriber database. Receiving up to 50,000 changes every day, with information supplied from BT and most other major telecoms companies, the file holds over 27 million subscriber records; including more than 11 million standard consumer listings and over 12.5 million ex-directory consumer records, for which an XD flag can be applied.

Invaluable to those businesses that rely on the telephone as a primary channel to market, screening against the BT file ensures that call centres operate at maximum efficiency.

By populating empty database fields, amending inaccurate numbers and highlighting those records for which no telephone number could be found, this process minimises wasted effort and resource, reducing costs and improving ROI whilst ensuring that brand equity is not affected by poorly targeted calls. Agent morale and productivity is also sustained at higher levels by reducing connection failures and irritating calls to incorrect recipients.
