Experian is a partner in the UK governments Verify ID system and USPD Address Validation. In the UK during the 1970s, GUS plc, a retail conglomerate with millions of customers paying for goods on credit, employed John Peace, a computer programmer at the time, to combine the mail order data from various GUS businesses and create a central database to which was later added electoral roll data as well as county court judgements. GUSs database was commercialised in 1980 under the name Commercial Credit Nottingham (CCN). In 1996 GUS plc acquired the US credit reporting business Experian, formerly known as TRW Information Services, from Bain Capital and the Thomas H. Lee Partners and merged it into CCN. During the next ten years, Experian broadened its product range to new industry sectors, beyond financial services, and entered new markets such as Latin America, Asia Pacific and Eastern Europe. The business expanded through both organic development and acquisitions. In October 2006 Experian was demerged from the British company GUS plc and listed on the London Stock Exchange.
