Today, Mytour will show you how to find the 7-digit serial number or warranty code on the service tag of your Dell product. This service tag is unique to each product and is typically requested by Dell when you need customer support. Every modern Dell product comes with a service tag label, but this label may fade over time. If the label on your laptop or tablet is worn out or missing, you can still find the service tag using Windows, Linux, or Android.
Steps
Find the label on any Dell product
Look for the label on the laptop. This tag is usually white or black with contrasting characters, and is often located near the battery compartment underneath the laptop. Search for the 7-character alphanumeric code next to or below the words "Service Tag" (sometimes labeled as "Serial Number").
- Some laptops have a metal cover at the bottom that may obscure the label. If you can't find the label, simply lift this cover.
Locate the label on the desktop PC. Typically, a white label can be found near the top, on the back of the computer tower. In some cases, a black label with white text might be positioned at the top of the product. Wherever the label is located, it will display a 7-character alphanumeric code next to or beneath the words "Service Tag" (or "Serial Number" on older models).
- If you're using an All-in-One desktop, the white label with black text is usually placed on the back, near the bottom of the screen.
Find the label on the printer. For most integrated printer models, you will need to lift the scanner lid to locate a black label with white text titled "Service Tag". On older printer models, a large white label containing a barcode will be found either on the back of the unit or inside the ink cartridge compartment. The Service Tag consists of 7 alphanumeric characters.
Locate the label on the monitor. Look at the back of the monitor to find a black and white label with the title "Service Tag", containing a code made up of 7 alphanumeric characters.
- Not all monitors will have a Service Tag label. If you can't find it, refer to your product invoice.
Find the label on the tablet. A black label with white text displaying the words "Service Tag" is typically affixed to the back of the tablet. Alongside this, you will find a 7-character alphanumeric code that you need to provide when requesting support from Dell.
Locate the label on the projector. The Service Tag label, which is black with white text, is often found on the underside of the projector. If the label is not visible, check inside the carrying case. The label will include the words "Service Tag" or "Serial Number", along with a warranty code containing 7 alphanumeric characters.
