All Dell computers use Service Tags to help identify them. The tag is a unique seven digit code that you use whenever you need to download drivers, get help or identify compatible accessories. Alongside the Express Service Code, the codes are your gateway into the Dell ecosystem.
There are three places Dell usually places the tags, in the software, under the badge and underneath the laptop. Where the Service Tag is depends on the hardware in question. For laptops it is usually underneath or under the badge. In a desktop it can be at the back near the ports or behind the drive door at the front. Smaller devices have the Service Tag underneath.
