Learn how to find the serial number and other information that can help you identify your MacBook.
Locate your serial number, model identifier, and part number
You can find the serial number and other identifiers for your MacBook in macOS, on the computer’s surface, and on its packaging.
In the About This Mac window
With most versions of macOS, you can find your computer’s serial number and model information in the About This Mac window.
Choose Apple () menu > About This Mac. The window that appears lists your computer’s model name—for example, MacBook Pro (13-inch, 2016, Four Thunderbolt 3 ports)—and serial number. Your serial number can really help SimplyFixIt to offer you personalised advice on repairs or upgrades for your model.
You can also use your computer’s model identifier to get more information. In the About This Mac window, click System Report. In the System Information window that opens, find Model Identifier in the Hardware Overview section. Then use the identifier to locate your MacBook below.
On the surface of your MacBook
Close your MacBook and turn it over. The serial number is on the underside of the computer, near the regulatory markings.
On the original product packaging or receipt
If you still have the original packaging for your MacBook, you can find the serial number on a barcode label on the box.
The packaging also lists the Apple part number—for example, MLH72xx/A. Match that number to one in the list below to find your MacBook model.
In Apple part numbers, the “xx” before the slash are variables that differ by country or region.
The serial number, model number, and configuration details of your MacBook might also appear on its receipt or invoice.
Click on each model for repair & upgrade options.
