Finding the Sticker

Some laptops, including XPS and Precision models, have a flap over the sticker. If you don't see a sticker on the bottom of your laptop, lift the flap to expose it.

On a desktop or all-in-one PC. On a Dell desktop computer, you'll usually find the black or white sticker containing the service tag on the top, side, or back panel of the tower. On an all-in-one PC, the sticker is typically on the back of the monitor near the bottom.

On a laser printer, you'll find the service tag inside the toner compartment or bay.
On an inkjet all-in-one printer, lift the scanner lid to find the service tag sticker. [2] X Research source
Depending on the printer, you may also see the service tag sticker on the back panel.

On a monitor. If you have a Dell monitor sold in 2016 or later, you'll find your service tag on the back panel of the monitor. If your monitor is older, it does not have a service tag—instead, you can identify your monitor model by signing in to https://www.dell.com/support. [3] X Research source

On a tablet. On most tablets, you'll find your service tag on a narrow black sticker on the bottom edge of your tablet. On other tablets, you'll see the sticker on the back side of the tablet toward the bottom-right edge. [4] X Research source

If you don't see a sticker, check the storage bag that came with the device. Just look for the words "Service Tag" or "Serial Number" to find the 7-digit Service Tag code.

Turn off your Dell desktop or laptop PC. If you can't boot your computer into Windows or Linux and don't see the service tag sticker, you can access the service code from the BIOS. Begin by powering the computer off.

Turn the PC back on and press F2 on the Dell logo screen. You'll need to be quick with this move—make sure you press this key as soon as you see the Dell logo. Press it several times quickly, and don't stop until you see the BIOS or UEFI screen.

Select the System Information or Overview section. The BIOS (or UEFI) will be different on each system, but you'll find the service tag is in a section with one of these two names.
