Learn how to find the serial number of an iPhone, iPad, iPod, HomePod, Mac, or other Apple product.
Depending on the product, you can find its serial number in one or more of these ways:
Check the surface of your product for a printed serial number.
On Mac, choose Apple menu > About This Mac.
On iPhone, iPad, iPod touch, Apple Vision Pro, or Apple Watch, go to Settings > General > About.
If you use the Finder or iTunes to sync your device with your computer, plug your device into your computer, then select your device in the Finder or iTunes.
If you have your product's original packaging, you can check the barcode to find the serial number. You can also find your product's serial number on the original product receipt or invoice. Or choose a product below for details about finding the serial number.
Apple registration numbers and Apple hardware product serial numbers use the numbers 0 (zero) and 1 (one) instead of the letters "O" or "I".
Barcode scans of Apple product boxes might display a leading letter "S" before the product's serial number; however, the leading letter "S" isn't a part of the serial number.
