- Under the Battery (If Removable): If your laptop has a removable battery, the product number might be located on a sticker underneath the battery compartment. Power off the laptop, disconnect the power adapter, and carefully remove the battery to check.
- Inside the Battery Compartment (Even if the Battery Isn’t Removable): Some laptops have the product number located inside the battery compartment, even if the battery isn’t designed to be easily removed. In these cases, it might be visible by carefully shining a light into the compartment after the battery has been removed. However, do not attempt to force the battery removal if it seems difficult.
- On the Laptop’s Frame or Hinge: Less common, but sometimes manufacturers will print or engrave the product number on the laptop’s frame, near the hinge, or along the edges of the screen. Examine these areas closely, especially if the bottom label is missing.
Important Tip: The product number might be labelled as “Serial Number,” “S/N,” “Product Number,” “P/N,” “Model Number,” or “Model.” Be sure to carefully distinguish between these terms. The model number is generally a shorter, more generic identifier, while the product number (or serial number) is the unique identifier for your specific device.
Using the Operating System
If the physical label is damaged or missing, you can often find the product number using your laptop’s operating system. The method varies depending on whether you’re using Windows, macOS, or Linux.

Where can I usually find my laptop’s product number?
The product number, also sometimes referred to as the model number, is typically located on a sticker attached to the bottom of your laptop. Look for a small, rectangular sticker that contains various identifying information, including serial numbers, model names, and regulatory information. The product number is often labeled explicitly as “Product Number,” “Product No.,” “Model Number,” or simply “Model.” In some cases, it might be printed on a larger label alongside the serial number and other manufacturer details.
If you can’t find the sticker on the bottom of your laptop, check inside the battery compartment (if the battery is removable) or under the keyboard. Some manufacturers place the product number in these less obvious locations for security or aesthetic reasons. Additionally, the original packaging your laptop came in should also have the product number clearly printed on a label. The purchase invoice or receipt from the retailer will also likely contain this information.
Why is the product number important?
The product number is crucial for identifying the exact specifications of your laptop. Unlike a general model name, which might encompass several slightly different configurations, the product number uniquely identifies your specific hardware setup. This includes the processor type, RAM size, storage capacity, graphics card model, and other internal components. This level of detail is essential when you need to install drivers, download updates, or seek technical support.
Using the product number, you can easily access the correct drivers, firmware, and software updates for your laptop directly from the manufacturer’s website. This ensures compatibility and avoids potential issues caused by installing incorrect versions. Furthermore, customer service representatives often require the product number to accurately diagnose and resolve any problems you may be experiencing with your device, ensuring they provide the most relevant and effective assistance.
What’s the difference between a product number and a serial number?
While both are unique identifiers, the product number and serial number serve different purposes. The product number identifies the specific model and configuration of your laptop, telling you about its hardware and software components. It’s like a blueprint, describing what your laptop *is*. Think of it as the type of car you own, such as a “Ford Focus SE 2023.”
The serial number, on the other hand, is a unique identifier for *your* individual laptop. It’s like the VIN of a car. No two laptops will have the same serial number. This number is used for tracking the device’s warranty, registration, and repair history. If your laptop is stolen or requires servicing, the serial number is essential for proving ownership and tracking its progress through the repair process.
Can I find the product number through my laptop’s operating system?
Yes, most operating systems provide a way to access the product number directly through the system information. On Windows, you can typically find it by searching for “System Information” in the Start Menu. In the System Information window, look for fields labeled “System Model,” “Product Name,” or similar. The product number may be listed here, or you may find a more general model name that can be used to find the specific product number on the manufacturer’s website.
On macOS, you can find the product number by clicking the Apple menu in the top-left corner of the screen and selecting “About This Mac.” In the “Overview” tab, you’ll see the model name and year. You can then click on “System Report” to find more detailed information, including the serial number. Using this model information, you can visit Apple’s support website and enter the model to find the specific product number associated with your device’s configuration.
What if the product number sticker is damaged or unreadable?
If the product number sticker is damaged, faded, or missing, you can still retrieve the information through your laptop’s BIOS or UEFI settings. Restart your laptop and press the appropriate key to enter the BIOS/UEFI setup screen (usually Delete, F2, F10, or F12, depending on the manufacturer). Once in the BIOS/UEFI, navigate to the “System Information” or “Main” tab. The product number (or model number) should be listed there alongside other hardware details.
Another option is to use command-line tools within your operating system. In Windows, open Command Prompt or PowerShell and type the command “wmic csproduct get name, identifyingnumber, vendor, version” and press Enter. This will display information about the computer, including the product name (which might be the product number), the serial number, and the manufacturer. On macOS, you can use the Terminal application and type “system_profiler SPHardwareDataType” and press Enter. This will display detailed hardware information, including the model identifier, which can be used to find the exact product number on the manufacturer’s website.
Can I use the product number to check my laptop’s warranty status?
Absolutely! The product number is essential for checking your laptop’s warranty status. Almost all major laptop manufacturers offer online tools that allow you to check your warranty by entering either the product number or the serial number. These tools will provide information about the warranty’s start and end dates, as well as the type of coverage included. This is particularly useful if you’ve lost your original purchase documentation.
To check your warranty, simply visit the support section of your laptop manufacturer’s website (e.g., HP Support, Dell Support, Lenovo Support). Look for a section labeled “Warranty Check,” “Warranty Status,” or similar. Enter the product number or serial number as prompted, and the tool will retrieve your laptop’s warranty information. This information is crucial for determining if your laptop is still covered for repairs or replacements, saving you potentially significant expenses.
What should I do if I still can’t find my laptop’s product number?
If you’ve exhausted all the standard methods and still can’t find your laptop’s product number, your best bet is to contact the manufacturer’s customer support directly. Provide them with as much information as you can about your laptop, such as the approximate purchase date, general model name (if known), and any distinguishing features. They may be able to identify the product number based on this information or provide alternative methods for retrieval.
Another helpful step is to check your email archives for any communications related to your laptop purchase, such as order confirmations or registration emails. These emails often contain the product number or model number. Also, if you registered your laptop with the manufacturer, your account profile may contain the product number. Finally, if you had any previous repairs done on the laptop, the repair records might contain the product number as well.
