On Dell Latitude, Inspiron, XPS, Precision, Vostro and Alienware laptops, the service tag and the express service tag are seven- and 10-digit codes, respectively, that are located on the bottom of the laptop. Desktops also have these numbers, which are located on the back, top or side of the system.
Desktops with these numbers include Dimension, Inspiron, Optiplex, XPS and Vostro models, in addition to Alienware and Precision Workstation desktops.
The location of the service tag and express service tag varies on printers depending on the type of printer. The service tags are located on the bottom of the case for the smaller inkjet or mobile printers. The service tags are located inside the lid of the printer on all-in-one inkjet printers. On laser printers, the service tag is located either inside the toner compartment or on the back of the printer.
Dell service tags are also located in various locations on Dell peripherals and accessories. On Dell Venue tablets, the service tag can be located by going to the Settings and tapping About Tablet. Some tablets may have the service tag numbers on the door that covers the SIM or SD card slot. On the Dell XPS 10, the service tags are located at the bottom edge of the bezel.
