Learning has never been so easy!

Sometimes the actual serial number is under the battery, but generally all you need is the Service Tag (on the bottom) when dealing with Dell.

  • Finding the serial number on a laptop is tricky if you don't know where to look. Laptops generally have several tags containing various codes. On a Dell laptop, the serial number is located on the bottom of, or underneath, the computer. The serial number identifies a laptop and is used as proof of ownership.
  • How to get your Dell Service Tag from the command line in Windows and Linux There’s plenty of times you can need the serial number (aka Service Tag) from a Dell machine, but not be able to physically look at the label.

If you're like me you're rarely sitting in front of your customer's hardware. These simple steps will allow you to find the Service Tag for your Dell hardware without looking on the device.

3 Steps total

Step 1: Open command prompt

Go to Start > Run and type cmd to start your command prompt. Administrative rights are not required to run this command.

Choose either method 2 or method 3 depending on your circumstances.

Step 2: Obtain Service Tag locally with command line

In the command prompt type the following and press Enter/Return.

wmic csproduct get vendor,name,identifyingnumber

Step 3: Obtain Service Tag remotely with command line

If VNC or remote desktop connection to the remote-host is not available, execute the following from the local-host to get the service tag of the remote-host.

wmic /user:administrator /node:remote-host bios get serialnumber

You will be prompted for the password for account administrator.

NOTE :: type the command exactly like it appears above only replacing the remote-host part with the workstations name or IP address you're querying. If you want to use a user account other than administrator, replace 'administrator' with the account you wish to use.

    bryan try the following

    wmic /user:administrator /node:YOURPCNAME bios get serialnumber

    You'll be prompted for your administrator account. If you want to use another account replace administrator with your account name.

    I should have specified which commands are to be customized to fit your environment. My apologies. This should work for you.

    If you use ' wmic csproduct list brief' it puts out in a better format.

    this small capability has been a life saver when students have worn off the sticker underneath a machine from repeatedly inserting and removing from charging stations, carts, or bags.

Find Dell Laptop Serial Number Search


All Dell computers use Service Tags to help identify them. The tag is a unique seven digit code that you use whenever you need to download drivers, get help or identify compatible accessories. Alongside the Express Service Code, the codes are your gateway into the Dell ecosystem.
There are three places Dell usually places the tags, in the software, under the badge and underneath the laptop. Where the Service Tag is depends on the hardware in question. For laptops it is usually underneath or under the badge. In a desktop it can be at the back near the ports or behind the drive door at the front. Smaller devices have the Service Tag underneath.
