You must be 62 years old to apply for social security, however, you will receive less if you apply at 62 than if you wait until your full retirement age. Prior to 1983, full retirement age was 65. The law was changed and now your full retirement age is based upon the year you were born. You can use this calculator to determine your full retirement age. Understanding social security laws and benefits is a challenge for many people. Don’t go it alone! Marken Law can help you apply for social security and guide you through the process.
