What does a model number tell you?

How do I find the model number of my computer?

Do all computers have a model number?

Where do I find my computer's serial number?

A computer's serial number is often printed on the underside or backside of the machine. If you can't see it, or the tag has been removed, look in the device's system settings or under warranty information. You might also try searching online using your PC's make and model.

What information is contained in a PC's model number?

Each manufacturer has its own conventions when crafting model numbers and product codes. Most include details like operating system version, processor type, graphics card family and sometimes memory capacity. Some numbers may indicate region or country variations.

No, of course not. Model numbers are used for just about every product made today. Printers, TVs, smartphones, gaming consoles—they all have identifying model numbers.

Can I use a model number to compare two computers?

It depends on what information you can discern from the model number alone. If the number is broken into understandable parts that indicate particular components within the PC, then yes.

What's the difference: service tag vs. model number?

A service tag is typically used for diagnostic purposes and consists of a set of numbers and letters that identify your computer and its specific hardware configuration, software license terms and other technical details. But it doesn't tell you what type of device you have like a model number does.

How can I learn my PC model number if I can't find the label?

If you can't find the model number label on your computer, or if it's not readable, there are other ways to find it.

And depending on the system, the number might be printed on the bottom of the machine or, if it's a laptop, hidden behind the battery.

How do I know if my laptop's model number is correct?

Are there advantages to knowing my laptop's model number?

Knowing your laptop's model number can be helpful in researching its specifications, finding compatible accessories, and updating software applications. It's also needed to find driver updates to help your system run better, or to seek technical support or repairs from the manufacturer.
