Linux Dell Server / Desktop / Laptop Find Out Service Tag Command

Author: Vivek Gite Last updated: August 30, 2020 3 comments

I need to find out the service tag of my Dell server or computer. How do I find out my unique five- to seven-digit alphanumeric (letter and number) service tag code without looking at the back of the system or opening the door of bezel? Is there is Linux command to get the Dell service tag from the Terminal?

You need to use the dmidecode command to find out Dell servers or laptops service tag under Linux operating systems. It is a tool for dumping a computer’s DMI (some say SMBIOS) table contents in a human-readable format. This tool can display serial number or dell service tag without looking on the back of the server.

Linux Find Out Service Tag Command

Type the command as follows as root user:
# dmidecode | grep --color -i serial
OR
# dmidecode -t 1
Sample outputs:

# dmidecode 2.9
SMBIOS 2.6 present.

Handle 0x0100, DMI type 1, 27 bytes

How do I get my Dell device’s service tag?

We can also use the following syntax:
$ sudo dmidecode -s system-serial-number
To find out Express Service Code for Dell server or laptop or desktop running Linux run the following bash command:

echo "Service tag for this Dell system is:"
sudo dmidecode -s system-serial-number
echo "Express Service Code for $HOSTNAME is:"
echo $((36#$(sudo dmidecode -s system-serial-number)))

Service tag for this Dell system is:
T2Y9LA7
Express Service Code for nas01.sweet.home is:
35250176053

Using bash for loop to get Dell service tag on Linux

Type:

for d in system-manufacturer system-product-name system-serial-number bios-release-date bios-version 
do    
  echo "${d^} : " $(sudo dmidecode -s $d)
done

Outputs from CentOS 8 running on my Dell system:

System-manufacturer :  Dell Inc.
System-product-name :  Precision M6700
System-serial-number :  ABCXYZ112
Bios-release-date :  11/30/2018
Bios-version :  A20

Conclusion

You learned about various Linux commands to get the Dell service tag, including Express Service Code from the Terminal or bash. Linux CLI option is useful when our server is located in a remote data center, and we can not read the service tag from chassis. However, Dell stores Service Tag in the BIOS/firmware system and is available with the easy to use dmidecode Linux command-line utility.
