How to Apply for a Social Security Number

Partially covered Social Security Card

In the U.S., a Social Security number (SSN) is a nine-digit number used to report your wages to the government and to determine eligibility for Social Security benefits. If you are employed in the U.S., you need a Social Security number to work.

  • Students in F-1 status are eligible for Social Security numbers as long as they have obtained an on-campus job. F-1 students automatically have permission to work on-campus.
  • Students in J-1 status are eligible for Social Security numbers as long as they have obtained an on-campus job. J-1 students do not automatically have permission to work on campus and must request authorization from ISSS. Students in J-1 status seeking on-campus work authorization, please submit a request in Interlink.

A SSN is not needed to obtain an Ohio driver’s license or Ohio state ID.
