The UK’s most comprehensive, accurate and reliable deceased identification file

Includes over 90% of all deaths including date of both birth & death

Removing deceased customers is essential to maintaining data accuracy, preventing identity fraud, and meeting the GDPR data compliance requirements. 

The National Deceased Register (NDR) is the only file available that can be used for customer identification, fraud, ID and suppression purposes.

NDR contains information on over 90% of all deaths dating back to 1995, with the majority of records capturing date of birth and date of death, making it ideal for use in updating customer information, fraud, ID, collections, anti money laundering and customer identification and suppression.

It is widely acknowledged to be the UK’s most accurate and reliable single source of deceased identification & suppression data. It is used by majority of the country’s CRA’s and corporations to ensure their data is maintained to the highest standards.

When approached by the Ark to take on the NDR we gave them fair warning that, where it comes to evaluating new data sources, the AA are not an easy organisation to do business with. Happily, for both parties, the NDR stood up to some pretty heavy scrutiny and has now been embedded into our business on what we anticipate will be a long term basis.
