Finding my MAC/ address

A MAC address (Media Access Control address, also known as an Ethernet address) is a unique numeric identifier used to distinguish a device from others on a network. The address is assigned by the manufacturer for Ethernet and Wi-Fi cards. Your device therefore is likely to have two MAC addresses.

Your MAC address is listed as six groups of two hexadecimal digits, separated by hyphens, e.g. 00-13-02-80-92-7A. To find your MAC address, please go to the appropriate operating system below.
