If you do not have a Social Security Number (SSN) and would like to apply for one, or if you have one and do not remember the number, you should contact the Social Security Administration at https://www.ssa.gov/.
Note: You most likely do not need an SSN to vote. Identification requirements vary depending on the state in which you are voting. Most states accept forms of ID other than a Social Security Number. For more information regarding your state’s ID requirements, visit our State Voting Requirements page.
