AirTag A2187 setup fails with 'Could Not Complete AirTag Setup' error

I need help with an AirTag that I cannot add to my Apple Account. The AirTag is not shown in Find My → Items. I use the same Apple Account on an iPhone 15 Pro and an iPhone SE (2020), and both devices give exactly the same error: “Could Not Complete AirTag Setup — To set up this AirTag, sign in with your Apple Account in Settings.” I am already signed in to the Apple Account and all required Find My, Bluetooth, Location Services and iCloud settings are enabled. The AirTag is model A2187. It was previously paired with my iPhone 15, which was factory reset before I removed the AirTag from Find My. Please check whether there is an AirTag association or Find My registration problem with my Apple Account.

Hi there

Please try this

Reset the AirTag: Press down on the stainless steel battery cover, rotate counterclockwise, remove the battery, put it back in until it clicks and makes a sound, and repeat this process five times total to factory reset the tracker.

Check Terms & Conditions: Sign out and back into iCloud, or open find my to verify if pending iCloud Terms and Conditions need acknowledgment on your device.

Toggle Settings: Turn off Location Services and Bluetooth, restart your iPhone, and turn both features back on.

Verify Account Association: If the error persists across multiple devices after a hard reset, the secure element inside the AirTag may retain a lingering association from the previous pairing; contact Apple Support to disassociate the hardware serial number from backend servers.
