You can apply for Social Security benefits as early as 62 years of age. This is if you are applying for retirement benefits. Remember, earlier retirement will equal less money. For Social Security Disability, you can apply at any age, or if your under 18 a parent can apply for you, as long as you have worked a specific amount of time (depending on state). If you have never worked, you can apply for Supplemental Security Income (SSI) at any age. You should receive a Social Security outline every year about one month before your birthday, via postal mail. Check it to see how many ‘work points' you have acquired and how much you would receive if you applied for any type of Social Security now.
