Accurate & Reliable Deceased Identification File

NDR helps identify, flag and remove deceased customers and prospects from your database and is a key component in identifying fraud.

Introducing The National Deceased Register

The National Deceased Register (NDR) is the UK’s most accurate, reliable, and comprehensive deceased identification file.

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.
