Your rules are relatively clear, you can turn them into if/then statements.
Use length to get the length of the phone number and Catt to add prefix.
This assumes you have a character variable, but use PUT if you need to convert it.
If length(phone) <= 7 then new_phone = catt('00632', phone);
else if length(phone)=8 and substr(phone, 1, 1) = '2' then new_phone = catt('0063', phone);
else ... etc
