How to Find the MAC Address on a Device


This article explains how to locate the MAC address on different devices.

A Media Access Control (MAC) Address can be referred to as an Adapter Address, Physical Address, or Hardware Address. This address is a unique identification number assigned to each network interface controller (NIC) during manufacture.
