Some believe the answer to this question is a resounding YES, since you may hold your SS card in your right hand and/or you have it memorized inside ('burned' into) your forehead. It is also quite compelling to realize that Title 42 of the United States Code, Section 666 (yes, your 'leaders' deliberately gave this section the "Number of the Beast") mentions the SSN no fewer than 8 times and deals with revocation of occupational 'licenses' which can effectively render one destitute, "unable to buy or sell, save he have the mark."
Even newborns are now figuratively and ritualistically 'branded' in hospitals with their SSN 'marks' in accordance with the diabolical Enumeration at Birth Act which many people don't even know exists. If you find this information disconcerting, please conduct your own research, inform others, and upvote this post.
