How can I find my MAC address?

You can run ip address from a terminal or adb shell to get the MAC address. Specifically, ip address show wlan0 will give you the MAC for the Wi-Fi chip on most devices. The address is shown after link/ether on the second line:

22: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000

link/ether a0:b1:c2:d3:e4:f5 brd ff:ff:ff:ff:ff:ff

inet 192.168.0.12/24 brd 192.168.0.255 scope global wlan0

inet6 ab01::c23d:45ef:ab67:89c0/64 scope link


valid_lft forever preferred_lft forever

Thanks to Firelord for this suggestion.

Another alternative:

If you have BusyBox installed, you can run busybox ifconfig. That will give output similar to the following (note the HWaddr on the first line):

wlan0
  Link encap:Ethernet  HWaddr A0:B1:C2:D3:E4:F5


 inet addr:192.168.0.12  Bcast:192.168.0.255  Mask:255.255.255.0


 inet6 addr: ab01::c23d:45ef:ab67:89c0/64 Scope:Link


 UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1


 RX packets:993 errors:0 dropped:0 overruns:0 frame:0


 TX packets:747 errors:0 dropped:0 overruns:0 carrier:0


 collisions:0 txqueuelen:1000


 RX bytes:904409 (883.2 KiB)  TX bytes:125749 (122.8 KiB)

If you don't have busybox you could try running ifconfig alone, but the version on my device has no output (and ifconfig wlan0 just shows the IP address).
