What is a B-number and how do I find it?

Your service or B-number is a 10-digit reference number that is linked to your Openserve connection at a specific address, such as your home or business. This number helps us to identify your line and allows us to assist you more effectively when you want to upgrade your line, or if your line needs repair, for example.

You can find it to your Openserve ONT / WIFI device.

If you're having trouble locating your Openserve Fibre service number please contact your internet service provider for assistance.
