Luckily, there are plenty of easy ways to find your MacBook's serial number, even if you don't have the device on hand.

Why You Should Know Your Laptop’s Serial Number

Your MacBook's serial number proves your ownership of the device and allows repair technicians to access warranty information. Therefore, you'll need to know the serial number if your MacBook breaks down and you want to claim repairs through the warranty. The number can also show what parts your MacBook contains and how it was manufactured.

The police will also require your MacBook's serial number to process a report if it's stolen. You'll need to send the police report to your insurance company if you want to claim on your policy.

What Are Some Different Ways to Find Your MacBook's Serial Number?

Your Macbook's serial number appears on the underside of the device and the barcode sticker attached to the original box.

You can also find the serial number by clicking on the Apple icon (it’s probably in the top lefthand corner of your screen) and selecting “About This Mac.”

Alternatively, open the “System Information” app and click on Hardware. You'll see the serial number listed on the right-hand side of the pop-up screen.

If you don't have your MacBook on hand or it won't turn on, you can find the serial number on your original receipt, invoice or warranty document. Alternatively, you can access your MacBook serial number through the Apple ID website if you signed in to your device with your Apple ID.

Should You Share Your MacBook's Serial Number?

You should only share your MacBook's serial number in limited circumstances, such as with a police officer or repair technician. Occasionally, you might be asked by another party to share your serial number online. There's a small risk that someone could use the serial number to claim repair services fraudulently, so it's a good idea to keep it private.
