How to find the service tag on a Dell peripheral, accessory, or handheld device.
The Dell service tag is a seven character identifier that is unique to your product. In addition to the service tag, there is an Express Service Code which is a 10-digit numeric version of the service tag which can be typed into a telephone for call routing. While most Dell products have a service tag, some accessories and peripherals do not. As a general rule, desktop and notebook computers, servers and storage devices, printers, and mobile devices (such as phones or tablets) will have a service tag.
Some other Dell products that have service tags are projectors, larger high resolution monitors, Axim personal assistants, and Dell smartphones or tablets.
As a general rule, there are a few likely locations for a service tag on these devices. These include the back or underside of a projector or monitor, the lower edge of a monitor or tablet, inside the battery compartment of a portable device, or inside a SIM card or memory card cover.
Projectors can have a service tag label on the bottom or on the back connector panel.
If a monitor has a service tag, it should be on the back of the monitor. Most Dell monitors do not have a service tag, however.
While the Dell Axim is no longer in production, owners of the device will find the service tag label under the battery in the battery compartment. This is also the location for most Dell smartphones.
Dell tablets and other portable devices will have a service tag label on the outside edge of the device or inside a SIM card or SD card cover. The Dell XPS 18 tablet/AIO computer has the service tag label on one of the fold-out legs.
