Find out how to locate the serial number of an iPhone, iPad, iPod, HomePod, Mac or other Apple product.
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 may display a leading letter “S” before the product’s serial number; however, the leading letter “S” isn’t a part of the serial number.
