Hello, The DeviceID is generated by the 360 SDK itself and is saved/mapped in the datahub for an Identity when the Identity Binding event is sent. I will recommend you try the Diagnostics page in 360 (General Settings->Content Delivery->Diagnostics) and lookup the Identity ID which you know you have bound the Device ID for. You would be shown a table with all other Identities that are associated with that Identity. If you need to discuss further we can even talk over a Teams call? Regards! Ronald Mascarenhas
