The nine digit social security number of 600 20 2026 that you are asking about in your 1/21 post at http://www.fivedoves.com/letters/jan2008/jj121.htm must have been issued in Arizona in 1985 because if you enter the first 5 digits of 600 20 into the space under Five Digit Decoder on the page at http://www.stevemorse.org/ssn/ssn.html it shows that  the social security numbers beginning with 600- 20-XXXX were issued in 1985 in Arizona. 

 

Presidential candidate John McCain was born August 29, 1936 according to http://en.wikipedia.org/wiki/John_McCain  If he had a bank account, the bank would required his social security number. His social security number would also have been required on his annual federal and state income tax forms. In 1985, he would have been 49 years old so I am assuming that the social security number 600 20 2026 which you are inquiring about is not McCain's social security number since it would have been issued in 1985.  If his social security card was issued by the state of Arizona, I would assume it would begin with the first three digits of 526 or 527 which were issued prior to 1985.

 

And as a side note, the social security number of 600-60-0006 was issued in Arizona in 1988.
