Is Android advertisingId unique per device or per user account?

i tried to find out if the new Advertising Id from Google is unique per device or per google account? In general i would like to know what happens if someone has two devices connected with the same google account?

Same Question for the iOS IDFA.

Thanks in advance Philipp

As I look into developers page, I understand that Ads ID is user-specific unique (so unique per user not per device)

http://developer.android.com/google/play-services/id.html

The advertising ID is a unique but user-resettable string identifier that lets ad networks and other apps anonymously identify a user. The user's advertising ID is made available to apps through APIs provided in Google Play services.

Regarding iOS, as I checked reference, this is device-specific unique

advertisingIdentifier

An alphanumeric string unique to each device, used only for serving advertisements. (read-only)
