Your MacBook’s serial number is essential for repairs, warranty checks, and support. Here are all the reliable ways to find it quickly.
Why the serial number matters
- Repair requests and estimates
- Warranty and coverage checks
- Apple Support cases and recalls
- Theft reports and identification
Method 1: On the MacBook enclosure
On most models, the serial number is printed on the bottom case of the MacBook, usually near the hinge. On some older models with removable batteries, it may be found under the battery.
Method 2: On the original box
If you kept the original packaging, the serial number is printed on a label on the side of the box, along with other device details.
Method 3: In macOS
If your Mac still starts, you can find the serial number in the system:
- Click the Apple menu () in the top-left corner
- Select “About This Mac”
- The serial number appears in the window
Terminal alternative:
system_profiler SPHardwareDataType | grep "Serial Number"Method 4: Via your Apple ID
Even if your Mac does not turn on and the box is gone, you can often find the serial number in your Apple ID:
- Open appleid.apple.com
- Sign in with your Apple ID
- Open “Devices”
- Select your MacBook to view the serial number
Works even if the Mac is lost or faulty
If the Mac was associated with your Apple ID, the serial is shown in the device details.
Method 5: In the Find My app
If you have another Apple device with Find My enabled:
- Open the Find My app on your iPhone or iPad
- Tap the Devices tab
- Select your MacBook
- Scroll down to view the serial number
