Created by merging and deduplicating information from leading UK consumer data providers, the UKChanges date of birth confirmation file contains over 20 million records and is gathered through a variety of opted-in sources. Over 13 million of these records contain full date of birth, with the remainder providing the month and year of the individual’s birth.

Used to confirm existing date of birth information on user’s files, or append an age to submitted records, the data can be employed across the business, verifying information from application forms and enquiries to help combat fraud or ensuring the timely execution of age and birthday-related campaigns with accurate trigger dates. Date of birth information can also be used as an indication of household status, as an aid to profiling for age-specific products or, in the case of the insurance and life assurance markets, as a selection for premium-led campaigns.
