The Bluetooth MAC address is a detail most users never notice. Every Bluetooth device carries one: the address that lets two Bluetooth devices recognise each other and exchange data, in the same way a Wi-Fi adapter has its own address.
You meet it constantly without noticing. Pairing a wireless headset, sending a file to your phone, connecting a speaker: in every case the two devices first exchange their Bluetooth MAC addresses. Seeing only the device name tells you very little, and the name can be changed by whoever owns the device.
A brand lookup goes further. It reads the IEEE registry and shows which company actually registered that address, together with that company’s registered office address and region. To find the Bluetooth address of your own device, see the article below. How to Find a Bluetooth MAC Address
