The process of procuring the SSN is simple and free of charge. As you work and pay your taxes, you earn your 'credits'. Typically, you would require 40 credits to qualify for benefits. Social Security benefits replace a percentage of your actual earnings when you retire, become disabled or die. You receive a 'Statement' showing your earnings history, and an estimate of the retirement, disability and survivors' benefits you and your family may receive based on your earnings.
