CF83 form - how to apply for Class 2?

I can not find in a new CF83 form the option to mark Class 2. Is it OK to send a new CF83 form if I want Class 2? Can I send an old CF83 form for Class 2?

Hi Antanas1963,
The new online CF83 application forms do not ask which class of voluntary National Insurance contribution that you wish to pay.  Provided that you are entitled to pay the voluntary Class 2 contributions, our International Teams will accept your application at this rate.  If you are not entitled to pay the voluntary Class 2 contributions then they will accept your application at the voluntary class 3 rate.
If you would prefer to apply via the old paper CF83 application form then this is fine.
Thank you.
