Apple’s AirTag is a Bluetooth tracker that helps you find lost items. It runs some basic software to communicate its location back to nearby iPhones which can then act as beacons on the Find My network.
At the time of publishing, the latest software for the AirTag is version 1.0.255. It’s not yet clear how an AirTag’s software can be updated. With other Apple accessories like AirPods, the paired iPhone can wirelessly transmit new firmware over the Bluetooth connection periodically. We don’t know yet if the same is true for the AirTag.
How to find out your AirTag’s software version and serial number
If you want to find out the current installed software for an AirTag you possess, it is really simple. In the Find My app, select the AirTag from the list in the Items tab. Then tap on the battery life indicator in the swipe-up panel. Tapping on the battery indicator will toggle a new view that shows the serial number and software version of the accessory. Tap again to return to the last updated time and battery life status.
How to find out the serial number of any AirTag
If you want to find out the serial number of an AirTag that isn’t yours, there are two easy ways to do it. If you have an NFC-compatible iPhone or Android device, simply hold the AirTag near the NFC scanner on your phone. This will launch an Apple website that includes the serial number of the AirTag as well as contact information if the owner has put the AirTag into Lost Mode.
The serial number of the AirTag is also printed physically on the device itself, so you can still find out the information without being paired in the Find My app. To do this, press down on the stainless steel back of the AirTag and twist in anti-clockwise to remove the back cover. Remove the battery to reveal the AirTag’s serial number and other model identifiers and FCC information.
