If you’re eligible for Social Security disability (as opposed to SSI), you can file your application online. It used to be that, to file for disability, a Social Security or SSI disability claimant had to call the SSA (Social Security Administration), request that an application be taken for disability benefits, and then wait to be interviewed, either over the phone at a later date, or in person at the Social Security office. To file for disability today, these options still apply. In fact, for many individuals who need to file for disability, a phone interview is convenient and, to others, an office interview may be more comfortable. Many applicants like to have the assistance of an SSA field representative to fill out the application. However, a third option does exist today for the individual who needs to file an SSDI (Social Security Disability Insurance) claim: to file for disability benefits online.
