Experian Match release notes


Dec 12, 2017

Experian Match API v2.4.0

This release adds performance and stability improvements allowing for higher capacity processing, alongside general fixes and better default matching behaviour.

In addition, Match now allows the configuration of grouped elements of any input type opening up the ability to process multiple names, addresses and/or generic elements.


  • Stability improvements when processing large inputs.
  • Grouping ability allows multiple names, addresses and other generic input fields to be matched.
  • Updated rules and resources for UK and Australia leading to higher country address match coverage.
  • Stored Blocking Keys are stored securely using SHA-256 hashing.
  • New API method for retrieving default blocking keys per country.
  • Granular name elements, including Forenames and Surname can now be specified in input.
  • Better handling of non-alphabetic characters in Field group names.
  • Improvements to cancelled/failed job error handling.

Breaking changes

Any existing integrations with Match will need to be updated to account for the following changes: 

  • Search and Transactional operations will fail against existing Match Stores due to the new salt and hash of blocking keys. Consult the documentation for how to turn off hashing to continue using your existing sessions, or alternatively recreate your Match store.
  • Existing Match rules that include field groups for multiple generic strings will need to be prefixed by the field group name with a hash symbol e.g.


    Must now be written as


    This hash notation only applies to the field group when it is used in the rules; no changes are required to the blocking keys or input field mappings.
