Accepted device identifiers
Adjust recognizes the following advertising and device IDs as valid forms of identification for conducting attribution when provided within the parameters below.
Advertising and device IDs are defined as follows:
- Advertising ID
- Used explicitly for advertising purposes. Device users have the option to reset the ID or can refuse to share it (such as limit ad tracking settings).
- Adjust stores advertising IDs and they can be used for retargeting purposes
- Device ID
- Permanently attached to the device without users having the option to reset it or deny sharing rights
- Adjust does not track device IDs by default, nor do we store raw device IDs; we only use them for attribution purposes

*Adjust only uses the Android ID and MAC address for attribution when the
gps_adid is unavailable.
**The IDFV should be used when running cross-promotional campaigns (e.g., via email) targeting users with LAT enabled. The IDFV provides more accurate attribution than only relying on probabilistic matching.
