Azira identifies you by your phone, not your name. The form takes your details, but the identifier is the only link between you and the movement records held against you.
On Android it takes about fifteen seconds.
- Open Settings
- Tap Google, listed on some phones as Google Services
- Under the All Services tab, tap Ads
- The Advertising ID is the long string at the bottom
Azira's form says only to open the Settings app and click on Ads, which skips the part where Ads sits under Google. That omission is where most people give up.
On iPhone Settings won't show it. Apple hides the IDFA from users, which Azira acknowledges on the form, and it points to Apple's App Store search for IDFA utilities.
Reading it has a cost, so weigh it first. Since iOS 14.5 Apple returns 00000000-0000-0000-0000-000000000000 to any app that hasn't been allowed to track, so the utility only sees your real IDFA once you switch on Allow Apps to Request to Track under Settings > Privacy & Security > Tracking and allow that app when it asks. That hands a third-party app the same identifier and tracking permission this guide exists to take back, and deleting the app afterwards doesn't undo anything it already sent. If you go ahead, use a utility you trust, copy the value, switch Allow Apps to Request to Track back off, tell iOS to have apps you'd already allowed stop tracking, then delete the app. Don't submit an all-zero ID. It isn't your identifier, it can't match your records, and the request will look like it succeeded while doing nothing.
The same rule works in your favour. The apps feeding Azira only receive your IDFA if you allowed them to track, so if tracking has been off on this phone since iOS 14.5, there may be little or nothing keyed to it. The request matters most for apps you did allow, and for records from before 2021.
Copy the string somewhere before opening the form. It's long and case-sensitive, so paste it rather than typing it out.
