Product Serial Number

What is the KEF serial number?

The KEF product serial number is made up of 16 digits. You’ll need to enter the full number to register your product successfully online.

Where can I find the serial number?

It depends a lot on the specific KEF product. However, there are a number of locations where you should be able to locate it:

  • on the outer carton box of the product or
  • on the surface of the product or
  • on a sticker located on its back panel or on the bottom of the product. It will typically appear near a bar code


Some KEF products contain multiple serial numbers. However, you may simply input one of the serial number for record purchase, our system can map the remaining serial number for you.
