Methods for Finding Your HP Serial Number via Command Line
Several command-line tools can be used to retrieve the serial number of your HP device. The specific command and method will vary depending on the operating system. Let’s explore the most common approaches:
Windows Operating System
Windows provides several built-in tools and commands that can be used to access the system’s hardware information, including the serial number.
Using the Windows Management Instrumentation Command-line (WMIC)
The Windows Management Instrumentation Command-line (WMIC) is a powerful tool for querying system information. It’s a versatile option for retrieving hardware details, including the serial number. Open the Command Prompt as an administrator (search for “cmd” in the Start Menu, right-click, and select “Run as administrator”). Then, execute the following command:
wmic bios get serialnumber
The output will display the serial number associated with the system BIOS. Keep in mind that on some HP devices, the BIOS serial number might not directly correspond to the system’s serial number, especially on newer machines with more advanced hardware management. In those cases, you should try the next command.
wmic csproduct get name, identifyingcode
This command fetches information about the computer system product including the identifying code, which usually is the serial number. It is worth noting that, in certain cases, the above command may not work reliably.
Utilizing PowerShell
PowerShell is another powerful command-line shell and scripting language available on Windows. It offers more advanced capabilities compared to the traditional Command Prompt and is often preferred for scripting and automation tasks.
Open PowerShell as an administrator (search for “powershell” in the Start Menu, right-click, and select “Run as administrator”). Execute the following command:
powershell
Get-WmiObject win32_bios | select SerialNumber
This command retrieves the SerialNumber property from the Win32_BIOS class, which usually contains the system’s serial number. Similar to WMIC, this may not always provide the desired result, especially for all HP models. The code below provides a better approach.
powershell
Get-WmiObject win32_computersystemproduct | select IdentifyingNumber
The above PowerShell command is functionally similar to its WMIC counterpart and provides greater accuracy.
Using the HP Support Assistant
While not strictly a command-line method, the HP Support Assistant software, pre-installed on many HP computers, provides a user-friendly interface for accessing system information, including the serial number. If installed, simply search for “HP Support Assistant” in the Start Menu and launch the application. The serial number is usually displayed prominently on the main screen or within the “My Devices” section. You can access the serial number by clicking on “See more” and navigating to the section.
Linux Operating System
Linux offers several command-line tools for accessing hardware information, often relying on the dmidecode utility.
Employing dmidecode
dmidecode is a powerful tool for retrieving information about a system’s hardware from the Desktop Management Interface (DMI) table. This table contains details about the system’s components, including the serial number.
Open a terminal window. You may need to use the sudo command to run dmidecode with root privileges, depending on your system configuration. Execute the following command:
bash
sudo dmidecode -s system-serial-number
This command instructs dmidecode to extract and display the serial number of the system.
Alternatively, if the above command does not work, try:
bash
sudo dmidecode | grep Serial
This command pipes the output of dmidecode to grep, which filters the results to show only lines containing the word “Serial”. This can be helpful if the specific -s system-serial-number option is not available or doesn’t produce the desired output.
If you don’t have dmidecode installed, use your distribution’s package manager to install it. For example, on Debian-based systems like Ubuntu, use:
bash
sudo apt-get update
sudo apt-get install dmidecode
On Fedora or CentOS, use:
bash
sudo yum install dmidecode
Checking /sys/class/dmi/id
Another method involves directly accessing the system’s DMI information through the /sys/class/dmi/id directory. This directory contains several files that expose different aspects of the DMI data.
Open a terminal window and execute the following command:
bash
sudo cat /sys/class/dmi/id/product_serial
This command reads the contents of the product_serial file, which usually contains the system’s serial number.
macOS Operating System
macOS provides the system_profiler command for gathering system information, which can be used to retrieve the serial number.
Using system_profiler
Open the Terminal application (found in /Applications/Utilities/). Execute the following command:
bash
system_profiler SPHardwareDataType | grep "Serial Number (system)"
This command instructs system_profiler to retrieve hardware information and then uses grep to filter the output, displaying the line containing the serial number. The output should look something like this:
Serial Number (system): C02XXXXXXXXX
The “C02XXXXXXXXX” represents the serial number of your Mac.
Using ioreg
ioreg (I/O Registry Explorer) is a command-line tool for exploring the I/O Registry, which contains information about the hardware and drivers installed on your system.
Open the Terminal application. Execute the following command:
bash
ioreg -l | grep IOPlatformSerialNumber
This command searches the I/O Registry for the “IOPlatformSerialNumber” property, which usually contains the serial number of the device.
Finding Serial Numbers on HP Printers
Locating the serial number on an HP printer is essential for driver installation, warranty claims, and ordering replacement parts. While some printers display the serial number on the control panel, it’s often more reliable to find it using command-line methods. This is not available on all printers. In some cases, using the printer’s web interface is a better method to obtain such data.
Using the Command Prompt (Windows)
This method assumes that the HP printer is connected to your Windows computer via USB or network and that the necessary drivers are installed.
-
Open Command Prompt as Administrator: Search for “cmd,” right-click, and select “Run as administrator.”
-
Use wmic to query for the printer’s serial number: This typically only works if the appropriate WMI providers are installed for the printer, which is not always the case.
wmic printer get name, serialnumber
This command attempts to retrieve the name and serial number of all printers connected to your system. If successful, the output will display a table with the printer names and their corresponding serial numbers.
Using the Printer’s Embedded Web Server (EWS)
Most network-connected HP printers have an embedded web server (EWS) that allows you to access printer settings and information through a web browser. This is often the easiest and most reliable method for finding the serial number.
-
Find the Printer’s IP Address: Print a configuration page from the printer’s control panel. The configuration page will list the printer’s IP address. Alternatively, you can find the IP address through your router’s administration interface or using network scanning tools.
-
Access the EWS: Open a web browser and enter the printer’s IP address in the address bar. Press Enter.
-
Locate the Serial Number: The serial number is usually displayed prominently on the EWS home page or within a “Device Information,” “Status,” or “Information” section. The exact location may vary depending on the printer model.
HP Server Serial Number Retrieval
Finding the serial number of an HP server is crucial for warranty management, support requests, and hardware tracking. Here’s how you can retrieve it:
iLO (Integrated Lights-Out) Interface
HP’s iLO (Integrated Lights-Out) is a remote server management interface that provides access to various server functions, including the serial number.
- Access the iLO Interface: Open a web browser and enter the iLO IP address. You’ll need the iLO username and password to log in.
- Navigate to System Information: Once logged in, navigate to the “System Information” or “Overview” section.
- Locate the Serial Number: The serial number is typically displayed under the “System Information” or “Product Information” section.
Command Line Interface (CLI)
You can also retrieve the serial number using command-line tools if you have remote access to the server’s operating system.
Linux
Use the dmidecode command, as described in the Linux section above:
bash
sudo dmidecode -s system-serial-number
Windows
Use the wmic command, as described in the Windows section above:
wmic bios get serialnumber
Or, if it doesn’t work:
wmic csproduct get name, identifyingcode
HP System Management Homepage (SMH)
The HP System Management Homepage (SMH) is a web-based interface for managing HP ProLiant servers. If installed, it provides a convenient way to view system information, including the serial number.
- Access the SMH: Open a web browser and enter the server’s IP address, followed by the SMH port (usually 2381 or 50000). For example:
https://<server_ip>:2381. - Navigate to System Information: Log in and navigate to the “System Information” or “Overview” section.
- Locate the Serial Number: The serial number is typically displayed under the “System Information” section.

How can I find the serial number of my HP laptop using the command line in Windows?
The easiest method to find your HP laptop’s serial number via the command line in Windows involves using the Windows Management Instrumentation Command-line (WMIC) tool. Open Command Prompt as an administrator, then type the command wmic bios get serialnumber and press Enter. The serial number should then be displayed directly below the command.
This method leverages the built-in capabilities of Windows to access the BIOS information, where the serial number is typically stored. Alternatively, you could also try the command wmic csproduct get identifyingnumber if the first command doesn’t work. This retrieves the product’s identifying number, which is often the same as the serial number on HP devices.
What command can I use on a Linux system to retrieve the serial number of my HP device?
In a Linux environment, the dmidecode command is commonly used to extract hardware information, including the serial number of your HP device. Open a terminal and execute the command sudo dmidecode -s system-serial-number. You may need to enter your administrator password, as sudo grants elevated privileges needed to access system hardware information.
The dmidecode command reads data from the system’s DMI (Desktop Management Interface) table, a standardized way for manufacturers to provide hardware information. If the serial number is properly populated in the DMI table by HP, it will be displayed as the output of this command. If dmidecode is not installed, you may need to install it using your distribution’s package manager (e.g., sudo apt-get install dmidecode on Debian/Ubuntu-based systems).
Is there a PowerShell command to get the HP serial number in Windows?
Yes, PowerShell provides a convenient way to retrieve the HP serial number. Open PowerShell as an administrator, and use the following command: Get-WmiObject win32_bios | select SerialNumber. This command leverages Windows Management Instrumentation (WMI) to access the BIOS information.
The Get-WmiObject cmdlet fetches the Win32_BIOS class, which contains the serial number. The select SerialNumber part of the command then filters the output, displaying only the serial number. This is a more streamlined method than using the traditional wmic command in Command Prompt, especially within a PowerShell scripting environment.
What if the command line returns a blank or incorrect serial number?
If the command line returns a blank or incorrect serial number, there could be several reasons. One common cause is that the serial number was not properly written to the BIOS or DMI during manufacturing or system configuration. Another possibility is that the BIOS is corrupted or outdated.
To resolve this, first ensure that you are running the command with administrator privileges, as accessing system hardware information often requires elevated permissions. If the issue persists, consider updating your HP’s BIOS to the latest version. You can typically find BIOS updates on the HP support website for your specific model. If updating the BIOS doesn’t work, the serial number might not be stored in the BIOS, and you’ll need to physically locate it on the device itself.
Where else can I find the serial number of my HP device if command-line methods fail?
If command-line methods fail to retrieve the serial number, the most reliable alternative is to physically locate it on the device. HP typically places the serial number on a sticker attached to the exterior of the device. For laptops, this sticker is often found on the bottom of the chassis, underneath the battery (if removable), or inside the battery compartment.
For desktop computers, the serial number sticker is usually located on the side or back panel of the case. For printers, look on the back or bottom of the printer. Once located, carefully record the serial number, ensuring you accurately transcribe all characters and numbers. You can then use this serial number for warranty claims, driver downloads, or any other support-related inquiries.
Are there any third-party tools that can help me find my HP serial number?

However, it’s important to exercise caution when downloading and installing third-party software. Ensure you download from a reputable source to avoid potentially harmful malware or adware. Always read reviews and check the software’s reputation before installing it on your system. Additionally, some tools might not accurately detect the serial number if it’s not properly stored in the BIOS or DMI.
Does the command to find the serial number vary based on the HP device type (laptop, desktop, server)?
Generally, the command to find the serial number does not vary significantly based on the HP device type (laptop, desktop). The fundamental principle remains the same: accessing the system’s BIOS or DMI information. The wmic, PowerShell, and dmidecode commands attempt to extract this information regardless of the device’s form factor.
However, the success of these commands can depend on how the manufacturer has implemented the DMI or BIOS on each specific device. While the command itself might be the same, the accuracy and availability of the serial number data can vary. Therefore, if one method fails, it’s always advisable to try alternative methods or physically inspect the device for the serial number sticker.
