How to Check the UDID Matched?

What Is UDID?

The UDID of the Apple device is generated by four items: IMEI Number (iPad and iPod are ECID), Serial Number, Wi-Fi Address, and Bluetooth Address. It’s an acronym for Unique Device Identifier. When a user tries to activate the device using iCloud or the Setup application, it is a unique identifier for a single device obtained from Apple's servers. If the UDID Match status shows "No", it means that one of four items has been changed at least.
