Ownership state is a device’s current account, lock, and control status. It determines whether the person who has the device can legitimately set it up and use it. A phone may be physically reset yet still be linked to a previous owner’s account or blocked by an activation lock.
Checking ownership state matters when buying new or refurbished phones, tablets, and other connected devices. Before purchase, confirm that the device is released from prior accounts, can be activated with your own account, and is not subject to an undisclosed carrier or management lock. In real-world fraud, stolen or improperly resold devices may be offered without clear disclosure of these restrictions; defenders and buyers can reduce risk by verifying device status and purchase terms before handing over payment.
