"Please enter a valid billing account number"

Trying to link my broadband to my account to review the bills. I keep getting the error message "Please enter a valid billing account number". I copy-paste that number from the "Your new bill is ready"-emails I'm getting. Please advise.

Does it start with 'GB' followed by 8 digits?

You do have fixed Home BB? What plan? What router?

Yes, it starts with 'GB' followed by 8 digits. I've got a "Full Fibre 150 Essentials" broadband package with a "Smart Hub Plus".

Hey there @mivkov 👋

That number starting with GB is definitely the account number you want here.

I'd recommend giving this a try from a different device or browser, and if you continue to struggle from there please give our team a call.

They should be able to get this all linked correctly at our end 😊
