What is a laptop serial number?

OEMs give each product a unique number called a serial number. Even though the name only says “numbers,” a “serial number” is usually made up of both numbers and letters. With it, manufacturers can figure out which laptop they’re talking about when they need to give technical support or acknowledge a warranty process. A laptop’s serial number can also help you find it if it gets lost or stolen.


How many digits is a laptop serial number?

Most serial numbers have at least six or seven characters, and some have twenty or more. Some devices, such as those made by Acer, may have both a serial number and an SNID. But most of the time, when calling technical support, either number would work.

Is laptop serial number and device ID the same?

Device IDs are stored on the mobile device and are different from hardware serial numbers, which are assigned by the device manufacturer to identify a device and can be used for inventory purposes.

Why ask for laptop serial number?

If your laptop breaks down while it is still under warranty, the repair person will need to know the serial number. The number lets them see how many times the device has been fixed and what parts it has.
