How to Find Your Computer’s Serial Number/Service Tag


A serial number is a unique identifier tied to a specific hardware product such as a desktop, laptop, or printer. This identifier may also be referred to as a service tag.

Please note some UAH computers come with a white or silver label listing the UAH inventory number. This is not the device serial number or service tag.
