Tips

If you need tech support for your Dell computer, monitor, printer, or other device, you'll want to know your service tag number. The service tag is a unique 7-digit alphanumeric you can use to identify your product, get support, download drivers, and find compatible accessories. The easiest way to find your service tag is to look at the black-and-white sticker on your device. If the sticker is missing or worn down, you can also find the service tag in the SupportAssist app, in the BIOS, and by running a simple command. This wikiHow article will teach you all of the ways you can locate your Dell service tag for any product.

Things You Should Know

A service tag is a 7-digit alphanumeric code unique to your Dell device.
Service tags are printed on black-and-white stickers on all Dell computers, tablets, projectors, printers, docking stations, and monitors from 2016 and later.
You can also find the service in SupportAssist, the BIOS, and by running the command "wmic bios get serialnumber" in Command Prompt.
