Is it possible to know who created a customer address? I tried using a Saved Search with the internal ID of the address, the address book ID and the customer ID. The only bit that appears is some custom field change to the already created address but nothing more.

I think only if it changes the main address in the header level of the customer. Then it will be reflected in the the system notes. For the sublist only, I'm pretty sure not.

Thanks @James Morris

We used to use an employee name custom field on address record to track it and it was set to last employee who modified the address record.

Interesting, thanks @sam1128
