Reltio Identity 360 already contains a series of pre-configured match rules to aid in the task of identity resolution to make it as easy as possible for end users. All you have to do is load your data into your tenant and those rules will automatically identify duplicates. You cannot change them or add to them but if you want to see the rules that are already in place, just navigate to the data loader (accessible via the chocolate bar icon on the top right of your Identity 360 tenant), Select the "Individual" entity type and then select Match Rules. If you feel that additional rules are needed or existing rules should be changed, we would love to hear from you. This is the exact type of feedback we love getting from our users so we can make the product better.
