About to pay voluntary UK national insurance contributions

Hi I am just wondering I have been told that I can apply on the form CF83 online, however they are looking for uk identification which now I don't have. Is there any other way around it. They have told me that it will take longer to send it by post... what do I do?
 
Best is to read the key post and that should give you the information you will need to complete the claim end to end.
 
Did you create your UK Gateway account online, Where you uploaded your passport/ID?
 
At this point, I'm telling everyone to print, complete and post CF83 by recorded delivery.
