How do I apply for Social Security Disability? There are three ways to apply for Social Security Disability. The first way is to go on the Social Security website and apply for benefits online. The second way is to call the Social Security toll-free number and set up a phone appointment where a Social Security employee will call you and will take your application over the phone. The third way is to call me. My law firm will take you completely through the process. We will fill out all the paperwork for you with your help and see that it is submitted to Social Security.
