When you call DELL customer support for any help, they will ask for either Service Tag or Express Service Code. You also need service tag to download drivers and documentations from DELL support website.
When you have physical access to the system, you can easily identify the service tag affixed on the body of the server. DELL support site shows the exactly location of the service tag and express code stickers for various DELL equipments.
When you don’t have physical access to the server, you can get the same information remotely from the OS level. Using Windows or Linux command line you can easily get DELL service tag as explained below.
1. Get DELL Service Tag on remote Windows system
Login to the Windows remote-host using VNC or remote desktop connection. Use WMIC on Windows to get service tag as shown below.
C:\>wmic bios get serialnumber SerialNumber ABCDEF1
Following WMIC command will give make and model number along with service tag.
C:\>wmic csproduct get vendor,name,identifyingnumber IdentifyingNumber Name Vendor ABCDEF1 PowerEdge 2950 Dell Inc.
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.
C:\>wmic /user:administrator /node:remote-host bios get serialnumber SerialNumber ABCDEF1 [Note: Replace remote-host with the machine name of your remote-host.]
2. Get DELL Service Tag on remote Linux system
Login to the Linux remote-host using SSH. Use dmidecode on Linux to get service tag as shown below.
[remote-host]# dmidecode -s system-serial-number ABCDEF1
3. Get DELL Express Service Code From Service Tag
Service Tag is a base-36 integer. Once you have the Service Tag, you can calculate express service code yourself. Express Service Code is base-10 decimal integer of Service Tag. Dell uses express service code mainly for their support call-routing. When you call dell support, their automated call-routing system may ask you to enter express service code, which you can easily enter in your telephone, as it is just a bunch of numbers, instead of characters.
Use the following online tools to find express service code from service tag and vice-versa.
If you own systems other than DELL, such as HP, IBM, Sony, Toshiba, Acer etc., how do you find out serial number? Does the same method explained above works for you (or) Do you use a different method to identify serial numbers? Please leave your comment.

I had a lot of problems to look for Dell’s Service Tag
You can also give the type number for the information you wish to fetch.
So for getting the serial number of a machine you can use
# dmidecode –type 1
this will provide you all the information related to the machine.
I”m not getting wmic to run remotely via psexec. Is there some way to run it without logging on via RDP?
Thanks a ton…just this handy tip, and it worked great.
Thanks. A very useful tip! Works great on Citrix VM as well.
@Ruben, @Marcus, @Vidooshak,
Thanks for your comments. I’m glad you were able to use this article and identify the DELL service tag and express code on your servers.
Thanks for pointing out about the dmidecode command. For those who are interested, we wrote an article about dmidecode command that can be used to get the DELL service tag on Unix environment.
What is the error message you are getting while trying to execute wmic command?
Hello people, i see here that some of you are very knowledgable regards PC’s and scripting. I have a big predicament and would appreciate any assistance; i can not find my service tag for my Dell Precision M90. It is a 2nd hand refurbished laptop, which for some reason does not have a tag number in the BIOS (F2 setup) and because it is 2nd hand Dell have no direct record of this computer and are unable to help me at all! The Company whom i bought the laptop from are being very unhelpful to! Please help me to find the TAG for my computer so that i can finally address some of the issues i have been having, which ironically it seems i can only fix through the Dell website!
Your most gratefully Gareth
This works well for PE 2600s and up. I have a PE 2500 that has no serial information, and I also came across two 2600s that have the same serial information.
This will work for IBM Blade servers as well, though the tag information is in a different place.
I created a “lazy” batch file for me. Obviously you can expand on it, but this was all i needed. I used “ABCD123” as the serial place holder.
echo Host Name: %mchname%
for /f “tokens=3* delims= ” %%a in (‘ping -n 1 %mchname% ^| find /i “reply from”‘) do set ipaddy=%%a
echo IP Address: %ipaddy%
wmic /node:%1 bios get serialnumber
wmic /node:%1 csproduct get vendor,name,identifyingnumber
Host Name: pcname1
IP Address: 188.8.131.52
IdentifyingNumber Name Vendor
ABCD123 PowerEdge 2600 Dell Computer Corporation
Host Name: pcname2
IP Address: 184.108.40.206
IdentifyingNumber Name Vendor
0000000 IBM eServer BladeCenter HS20 -[ABCD123]- IBM

What about obtaining Dell Printer Service Tags??
Fantastic informatio. Nicely presented and very easy to follow. Thank you.
These are the coolest set of commands, ever!!
What if I’m not using Linux? Is there a command prompt in Windows XP I can use to accomplish the same thing?
i lost my laptop. i guess somebody has stolen it. i have the box with all the bar codes. help me how can i find my service tag number
Thanks for this, it really helped getting info on my remote servers

plz help me to find service tag number
It works on HP blade servers. Thanks!
I have tried several variations of the commands above. I am either getting “Access Denied” or “Invalid Parameter”. Here is the way that I tried, that I belive is correct but still not working.
Start -> Run -> CMD
wmic:root\cli>/node:%1 (where %1 = remote computer name)
wmic:root\cli>/user:administrator (prompts for password)
wmic:root\cli>bios get serialnumber
Node – %1
Description = Invalid parameter
If I do the above without the /authority:administrator line I get
Node – %1
Description = Access is denied.
What command would get you the make, model, service tag of a remote host?
Can someone please give a phone no. for Dell Support so I can enter my service tag & download sound driver?
Thanks a lot! I didn’t have access to the pc because they were in a meeting. I couldn’t contact them because they were in a meeting. We didn’t have the pc in our online inventory under service tag because we created the new system before they got their laptop. I knew they were logged on the network so I was able to use:
wmic /user:administrator /node:LOCALPCNAME bios get serialnumber
Worked like a charm. Asked me to log in with local password and I was able to find out the Serial so I could call for support.
Next, I used this to get the express code:
I regret to report that it did not work for me. I am in a Win2003 server Domain enviroment and this is what I get at the cmd prompt:
Enter the password :******
Node – marketing
Code = 0x800706ba
Description = The RPC server is unavailable.
Facility = Win32
Interestingly enough I get that no matter what the combination of local or domain administrator password as well as the node name.
Why would the RPC server be unavailable, this PC (e.g. marketing is ON an running with no errors whatsoever.
Of course running the same command locally there is no problem at all.
Obviously it does n’t like it when it runs over the network, but why?
What gives, can you please help.
I have a dell notebook whose display screen needs a replacement owing to damage. How can i get the stystem service tag pl.
wmic /user:administrator /node:machinename bios get serialnumber
but im getting the error ”invalid global switch”
I am not an expert on this. Let me know what am i doing wrong…
can we get the DRAC IP of the server in the similar way, the way you helped in getting the Serial number of the DELL box.
wmic bios get serialnumber
Ramesh : Thanks for the post..the article is really very helpful
I had the same issue and I just figured out what was happening. The name cannot contain a (/ or -) so I changed it to the IP and it works. Kind of sucks having to use the IP but it does work.
And just so this is out here on the web so Google can find it, here is how to get the Asset Tag and NOT the Service Tag. Everytime I searched for Asset Tag I got very few hits. They were all about the Service Tag. Anyway ….
wmic systemenclosure get SMBIOSAssetTag
We use our own barcodes on the systems and that number becomes the AssetTag.
Have any one encounter WMI engine failure in your Windows system resulting in Service Tag not able to be retrieve?
Here is my fixed solution WMI-Fix.bat script…
Kindly comments on any code improvements… I used it to together with OCS Inventory NG.
