How can I change my address on Air Tag ‘home’?

Hello, Nickoc12.

The address that your AirTag will use is tied to your Find My address, which may not be 100% accurate geographically, but it should be very close. You can try removing your AirTag from your iPhone and adding it back by following the steps in this article: Remove an AirTag or other item from Find My on iPhone - Apple Support

1. "Tap Items at the bottom of the screen, then tap the item you want to remove.
2. Bring the item near your iPhone.
3. If the item is not near your device, you can still remove it from your account. However, the item must be reset before anyone can register it to their Apple ID.
4. Tap Remove Item, then follow the onscreen instructions."

Once that is done, add it back by following these steps: Add an AirTag in Find My on iPhone - Apple Support

1. "Go to the Home Screen on your iPhone.
2. Remove the battery tab from the AirTag (if applicable), then hold it near your iPhone.
3. Tap Connect on the screen of your iPhone.
4. Choose a name from the list or choose Custom Name to type a name and select an emoji, then tap Continue.
5. Tap Continue to register the item to your Apple ID, then tap Finish."
