The agreement extends an existing licence with Trillium Software, a division of Harte-Hanks, and will enable BT to use TS Quality data software to obtain the user information in a drive for improvement in customer service and business performance.
James Gault, programme director of product and customer data platforms, said: "Customer name and address information is an extremely valuable BT asset.
"We must manage the quality of that data with strategic intent in all corners of the organisation.
"TS Quality is now BT's global standard for customer name and address data quality processing, helping us in the quest to ensure the accuracy of our data wherever and however it is stored or enters our organisation, so that it is fit for all of our business purposes."
TS Quality enables BT to standardise source data formats, to recognise and handle duplicates and to mould fragmented records into linked information.
Across multiple systems, this data quality schedule benefits hundreds of vital business processes such as regulatory compliance, sales and marketing, customer and account services and field service.
Ed Wrazen, vice-president for marketing international for Trillium Software at Harte-Hanks, said: "BT is to be applauded for recognising data quality as a strategic and enterprise issue."
