There's definitely an option to use the 11 digit new keeper number online, I used it for my bike at the start of the month.
To apply online you'll need either:
- the 16 digit reference number on your vehicle tax renewal letter (V11)
- the 11 digit reference number on your log book (V5C)
- the 12 digit reference number on your New Keeper Supplement (V5C/2) if you've just bought the vehicle
I don't have the V11 reminder, just the registration certificate or new keeper supplement
New keeper (using V5C/2 new keeper supplement document reference number)
Please type the 12 digit reference number from the front of your new keeper supplement (V5C/2)
Your V5C/2 document reference number can be found on the front of your V5C/2 :
