Dell Service Tag & Serial Number Lookup - Model & Line
Dell Service Tag & Serial Number Lookup - Model, Asset Tag & Device Lookup
The Dell Service Tag Lookup tool turns a Dell Service Tag into the device it was built as, using Dell's own published product records. Enter a 5-7 character Service Tag and receive detailed product information including the exact product name and the product line it belongs to. Ideal for IT asset managers who need to quickly identify and catalog Dell equipment. It works for any Dell device — Latitude, XPS and Precision laptops, OptiPlex desktops, Precision workstations, and PowerEdge servers — making it a fast Dell device lookup and product lookup in one place.

Frequently Asked Questions
How do I find my Dell Service Tag?
The Service Tag is a 5-7 character code printed on a label on the bottom of Dell laptops or the back or side of desktops and servers. You can also read it without the label: in the BIOS/UEFI setup screen, by running 'wmic bios get serialnumber' in Windows Command Prompt (or 'Get-CimInstance win32_bios' in PowerShell), or from the Dell SupportAssist app. Enter that Service Tag above to look up the exact model and product line.
Can I look up a Dell asset tag?
Usually, yes — the factory sticker most people call the Dell asset tag is the Service Tag, a 5-7 character code on the bottom or back of the device, and that is exactly what this tool looks up. Internal asset labels assigned by your own company live in your asset-management system, not in Dell's records, so those cannot be looked up here.
Which Dell devices can this identify?
Any Dell device with a Service Tag: Latitude, XPS, Inspiron and Precision laptops, OptiPlex desktops, Precision workstations, and PowerEdge servers. The lookup returns the exact product name and the product line it belongs to.
Is a Dell Service Tag the same as a serial number?
For practical purposes, yes — Dell uses the 5-7 character Service Tag as the device serial number on its laptops, desktops, and servers. If a label or BIOS screen shows a longer all-digit Express Service Code, that is the same Service Tag converted to numbers; enter the alphanumeric Service Tag here.
