A media access control (MAC) address contains 12 characters, consisting of numbers and letters. It is a globally unique identifier assigned to network devices. Your MAC address may have characters separated by a colon, dash, or a space. External wireless cards may have the MAC address printed on their label.


However, if your computer has an internal wireless card, you'll have to search for the MAC address in your operating system.
