HP PCs, Printers - Finding the Serial Number

This document is for all HP products.

Every HP product has a unique identifying number called a serial number. You need to know the serial number when you speak with support, service the product, or determine if the product is still under warranty.

HP Computers

Every HP computer has a serial number on the surface of the computer. You can also use your operating system (Windows or Chrome) to find the number.

note:
To learn how to find the product name or number, go to HP Notebook PCs - How Do I Find My Product Name or Number.

From Windows

For HP computers with Windows, find the serial number by pressing key combinations.

Use a key press combination to open a System Information window:
- Laptops: Using the built-in keyboard, press Fn + Esc.
- Desktops or All-in-One computers: Press Ctrl + Alt + S.
Find the serial number in the window that opens. If a System Information window does not open, continue with these steps.
In Windows, search for and open Command Prompt.
In the command prompt window, type wmic bios get serialnumber, and then press Enter.

The serial number displays.

From Chrome

For Chromebooks, locate the serial number from the login screen.

Press the Alt + V keys simultaneously.

The operating system version, firmware version, and serial number display in the top right corner of the screen. On an HP supported Chromebook, the serial number has 10 digits. On Chromebooks not supported by HP, the serial number format might vary.

Identifying the HP serial number on the login screen

From labeling on the computer

Search the outside of your computer for a number labeled as Serial Number, S/N, or SN. The number might display on a label or be etched on the product’s surface.

Examples of where you might find the serial number:

On the underside or back edges of the laptop
If you have a laptop with a removable battery, inside the battery compartment
If you have a detachable laptop, between the tablet and the dock (remove the tablet to reveal the serial number)
On the underside of the stand on some all-in-one computers

On the back of an All-in-One PC	On the side of a desktop PC
Outside of an HP Chromebook note: On an HP supported Chromebook, the serial number has ten digits, lists the product number, and has an HP label.

HP Printers

Every HP printer has a serial number applied to the surface of the printer. If you have connected the printer to a computer, you can also use HP software to retrieve the number.

From the labeling on the printer

Search your printer for a Serial Number, Serial No, S/N, or SN printed on a label. You might need to open the ink cartridge access area or scanner lid to reveal the label.

From the printer software (Windows)

You can find the serial number using the HP Printer Assistant, HP Solution Center, or HP LaserJet software installed on your computer.

Under Print, click Maintain Your Printer.

Double-click Device Information.

HP Monitors

Find the serial number of your HP monitor with the on-screen menu display, or on the outside of the monitor.

If your monitor is working, use the menu buttons on the monitor to open the on-screen menu, and then select Information. The serial number displays from the information window.
If your monitor is not working or the on-screen menu does not display the serial number, look on the back of the monitor, the underside of the pedestal, or under a cosmetic cover for a label with a Serial Number, Serial No, S/N, or SN.

Other HP products

For almost all HP products, the serial number can be found from one of the following locations.

A label applied to the product (usually on the underside)
Laser etching on the surface of the product
Inside the battery compartment
A purchase invoice or receipt
Product packaging or shipping box
Documentation that came with the product

Use a magnifying glass to find and read the serial number. For small items, such as accessories, the number might not be available from the product exterior and is only available from original product packaging, documentation that came with the product, or the invoice or proof of purchase material.

Supplies and consumables, such as ink or toner cartridges, do not have serial numbers.
