I believe that the starting age for drawing Social Security Retirement Benefits is 62 plus x number of months depending upon your birth date.
But the BEST suggestion that I can offer, (and the one that I've used to find answers to my own Social Security questions), is to make an appointment to visit with your local Social Security Office to get detailed answers and explanations to your questions.
Since you will be making an appointment by phone with Social Security, they will ask you what this is in reference to, and at that point you can start to explain your question(s).
The Social Security representative will tell you what you need to bring with you to the appointment, unless, of course, your question can be answered to your satisfaction on the phone.
