Are Shared Sets IDs globally unique?

[Oliver]

We noticed that some shared sets (e.g. negative keyword lists) are shared between accounts.  Is it safe to assume that the set IDs are globally unique?

Hi Oliver, 

Yes, the Ids of shared sets will be unique. You can run the Shared Set Report to get the details of the shared negative lists for each account including the ones shared by its manager accounts.
