Some exports of the Salesforce Audience Studio will contain mobile identifiers (MAIDs) like Android's AAID or Apple's IDFA, along with KUIDs and the client's first-party user IDs. Clients that use our hashed device ID will also see these IDs for some of their users. How can you tell which is which?
