This article explains where to find the MAC (Media Access Control) address for the Ethernet interface in an AirPort Base Station, as well as the MAC address for an AirPort card installed in the Base Station or computer.

On a local area network (LAN), the MAC address, also referred to as an ID or hardware address, is your computer's unique identification number. Each device on a network has a unique MAC address; those devices that support both wireless and wired networking will have a MAC address for both network interfaces.

AirPort Base Station

The AirPort Base Station Ethernet and AirPort (wireless) MAC addresses are on the bottom of the unit, below the serial number. They are shown as the Ethernet ID and the AirPort ID. Each Base Station has a unique Ethernet and AirPort ID.

AirPort Card

The AirPort Card's AirPort (wireless) MAC address is on the AirPort Card, below the serial number. It is shown as the AirPort ID. Each AirPort Card has a unique AirPort ID.

AirPort Application

You can obtain the AirPort Card and Base Station MAC address from the AirPort application, as shown in Figure 1. You need to select Show Details in main AirPort application window to view this information.
