How to Find the Serial Number of a MacBook
Each MacBook has a unique serial number, and you can find the serial number in a handful of different locations. Here are the most accessible places to find your serial number:
About This Mac: The serial number is on the About This Mac screen’s overview tab. If your Mac is already on, try this method. On the bottom of your MacBook: The serial number is printed on the bottom side of your MacBook. If the printing hasn’t worn off, this is the easiest method of finding your serial number. On the Apple ID account website: If you don’t have access to your MacBook, or it won’t turn on, you can log into the Apple ID account website to view the serial numbers of every Apple device you have registered.
While there are other ways, like running a system report or looking on the box your MacBook came in, these are the three most straightforward ways that work for pretty much every situation.
How to Find Your MacBook Serial Number in About This Mac
The Apple menu in macOS provides easy access to an About This Mac screen. If you have access to your MacBook, and it turns on, this is a simple way to find the serial number.
How to Find the Serial Number of a MacBook That Won’t Turn On
If your MacBook won’t turn on, the easiest way to find the serial number is to flip it over and look at the bottom. As long as the print there hasn’t rubbed off, you’ll find the serial number listed along with assembly, voltage, and safety compliance information.
How to Find a MacBook Serial Number if You Don’t Have the MacBook
If you don’t have access to your MacBook, or it won’t turn on, and the print on the bottom has smudged or rubbed off, you can find your serial number on the Apple ID webpage. For this method to work, you need to know the Apple ID and password you used when setting up the MacBook.
