Device record versioning is new

Starting April 2, 2018, you can track changes to device records using the new data elements Public Version Number, Public Version Date, Public Version Status, and Public Device Record Key.

Public Device Record Key is the primary key for device records on AccessGUDID: it can be used to uniquely identify a device record and maintain its history. Public Device Record Key will never change for an individual device record even if the device record’s Primary Device Identifier (DI) Number changes.

The table below shows the information you can expect to see in the new data elements Public Version Number, Public Version Date, and Public Version Status.
