Locate your Dell Desktop Service Tag
The Service Tag is a 7 alphanumeric character code, and the Express Service Code is a 10 to 11-digit code that is a numeric version of the Service Tag.
Dell uses these product identifiers to access information about your device’s specific tech specs and warranty so that we can provide personalized support options.
On Dell Desktops, the Dell Service Tag sticker is probably located on the back of the computer case, but can also be located on the top or side of the system.
Windows users can detect the service tag automatically with SupportAssist
