Display Dell System Service Tag using Command Line

Use Command Line to Display Dell System Service Tag


On  Windows system, all you need to display the service tag of a Dell computer desktop or server is built right into the operating system. Just open a command prompt window and rung the following command:  

c:\> wmic bios get serialnumber

On the very next line the Dell service tag will be displayed. On a HP server or desktop, the same command will return the serial number. This is the serial number that is used to look-up drivers, software, or parts for your server or computer desktop, laptop or other device. 
Dell BCM or other third party utilities are not needed. The service tag can be displayed in less than a minute or even seconds. Copy and paste the command into a Windows command window ("dos window" or "dos box") and hit enter. The functionality is built right into Windows.

This was so useful, thank you. I had to get service tag from a Dell server for which sticker tag that is normally put on all system was not legible. I was accessing the problem remotely wit ha regular computer user on-site. They were an average user and Was not capable of doing anymore than what I was telling them to do remotely. I was accessing the server with remote control software over the Internet. The access was kind-of slow and the browser had an issue. With the browser having an issue I was not able to download the service tag discover tool that Dell has from their support site. That tool to find the service tab works generally well and I think it uses the same type of WMI / WDM commands to get he serial number of the motherboard or chassis. Any, I ran the commands you posed and they worked perfectly. I was able to get the "serial number" service tag of the server from remotely.

Thank you. The command worked for me. I needed to get the service tag of a server. The sticker that comes on the server and desktop from Dell had been scraped off and the system, did not have Internet access at the time. I could not reboot to get it from the BIOS. This command worked perfectly.
