Identify citizens with this data matching tool

Identifying duplicate contacts within the Public Sector

Government agencies are focused on identifying contacts.

Because data is often stored and collected across a myriad of databases and is subject to change, identifying and matching duplicates is crucial.

The matching problem
If you are aiming for a single citizen view, improving data strategies or implementing CRM processes, you will faced with the challenge of multiple records.

Every year, name and address details are subject to change.

  • 10% of UK population move house
  • 300,000 marriages take place
  • There are 140,000 divorces
  • There are an estimated 40,000 deed poll name changes (in 2006)

Aid data sharing initiatives such as "Tell us Once", customer service provision and data migration projects by understanding these data changes.

The Experian Solution
QAS Identify uses reference data from Experian to match UK individuals. Duplicate contacts can be identified, even when the individual has moved house.

The intelligent knowledge base data, that covers most of the UK population, provides extra confidence in the matching achieved.

By utilising Experian's proprietary address links, you will receive a persistent person key, regardless of address moves, providing you with a true single person view.
'Family' and 'Household Keys' can also be appended to recognise links between individuals.
