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.

Increasing levels of Ex-Directory listings and TPS registrations over recent years have significantly reduced the pool of callable telephone numbers available through the BT OSIS file. Whilst the BT data remains the most current source of UK landline records, the file provides data managers with access to less than half of the telephone numbers in use today.

With the telephone remaining a vital, personal contact channel for organisations in many sectors, UKChanges has invested heavily in researching, testing and licensing alternative sources of opted-in UK telephone numbers.

The Extra Numbers dataset is the result of these ongoing efforts; combining the most significant, credible and complete sources of telephone numbers available to create a single resource where marketers can obtain the maximum possible accurate append rate from a single supplier - with minimum hassle.

Data contained in Extra Numbers is collected through a variety of contributors in different market sectors, all of whom expressly request permission for opt-in to third party marketing activity. The permissions obtained during collection override Ex-Directory status and TPS registrations, significantly increasing the pool of available data and providing an uplift in match rates of up to 50 percent when the file is used in conjunction with the BT OSIS database.

Screening against the Extra Numbers service will increase the amount of records on your database that can be used in telemarketing, sales and tele-research campaigns, extending the reach of your activities and the range of channels through which you can communicate your offer to potential customers. The effort invested in optimising the data before introducing it to the file also helps to maximise connection rates, reducing the cost per acquisition of telephone-based campaigns, improving the ROI achieved and helping to maintain the productivity and moral of calling agents.
