In this guide, we’ll walk you through multiple methods to find your laptop’s serial number on Windows, macOS, and even Linux. Let’s dive in!

Why Is Your Laptop’s Serial Number Important?

Before we get into the steps, let’s understand why the serial number matters:

• Warranty Claims – Manufacturers require the serial number to verify your device’s warranty status.
• Technical Support – Helps support teams identify your exact model for troubleshooting.

Method 1: Check the Physical Laptop (Easiest Way)

Most laptops have the serial number printed on a sticker somewhere on the device. Here’s where to look:

For Windows Laptops (Dell, HP, Lenovo, ASUS, etc.)

• Bottom of the laptop – Flip it over and check for a label.
• Under the battery – If your laptop has a removable battery, the serial number may be underneath.
• Inside the battery compartment – Some models hide it there.

For MacBooks (Apple Laptops)

• On the underside – Older MacBooks display it near the regulatory markings.
• Inside the Apple menu – Newer Macs store it digitally (we’ll cover this next).

Pro Tip: If the sticker is worn out, try using a flashlight to read it clearly.
