Learn different ways to find your Mac’s serial number.

1. The fastest way to find your Mac’s serial number

2. Turn over your MacBook

All MacBooks, or Mac computers in general, have the computer’s serial number imprinted on the back. However, it might not always be convenient to close your computer, or turn it around or upside down, or it might not be visible anymore after wear and tear.

3. Find serial number via Mac Terminal

If you’re tech-savvy and comfortable using the command line, fire up your Mac Terminal up and run this command:

system_profiler SPHardwareDataType | grep Serial

This will output the exact same serial number you can find under About This Mac and System Report > Hardware as you learned in the previous sections.
