HP laptops are extremely popular in India among students, professionals, small businesses, and home users. Every HP laptop has a unique Serial Number (usually 10 alphanumeric characters, often starting with 5CG, MXL, or similar). You need this number for:
- Checking warranty status on the HP website.
- Registering your laptop for support or extended warranty.
- Claiming service at HP centers.
- Selling or buying used laptops (common on OLX, Cashify, or local markets).
- Troubleshooting technical issues with HP support.
- Insurance claims or police verification (in case of theft).
This guide works on Windows 10 and Windows 11, which are most common on HP laptops in India.

1. Check Serial Number on the Physical Sticker (No Power Needed)
This is the easiest offline method.
- Flip your laptop upside down.
- Look for a white or silver sticker on the bottom panel.
- Find the field labeled Serial Number, S/N, or SN.
- The number is usually 10 characters long.
Additional Locations:
- Under the battery (if removable): Power off the laptop, remove the battery, and check inside the compartment.
- On the side or back of the laptop (some slim models).
- On the original box or packaging.
Tip: Take a clear photo of the sticker and keep it safe.
