Social Security Number

A Social Security Number (SSN) is a unique, 9-digit number used for taxpayer identification, income reporting, and record-keeping purposes. The Social Security Administration (SSA) issues the SSN.

You may only apply for a Social Security Number if you have an on-campus job or have been authorized for CPT/OPT. Once issued, the number is valid for one's lifetime. If you are not employed, you may apply for an Individual Taxpayer Identification Number (ITIN). Please click here for more information on ITIN numbers.

Many services require an SSN.

Social Security Letter for F-1 Students

Items to take to apply for your Social Security Number:

  1. Passport
  2. I-94 card (Print a copy at cbp.gov/i94)
  3. Form I-20 or DS-2019
  4. Downloaded & Completed Letter
  5. Completed copy of Form SS5, which can be picked up at Office of International Affairs or downloaded at ssa.gov/online/ss-5.pdf

You will not be able to get a SSN if one of the above items is missing. Take your application to the Social Security Administration Building. Please check the hours of the Social Security Administration Building as they vary throughout the week. We recommend arriving early in the day. You must wait at least 10 business days from the date on your I-94 card to apply for your social security number.

You may take the #2 COTA bus on High Street south to downtown Columbus. Ask the bus driver to let you off at the bus stop nearest 200 N. High St.

If you are working at Ohio State and receive payments, once you receive your permanent SSN, provide a copy of your Social Security card to the Office of the Controller by mail, fax or in person: Office of the Controller, 2nd Floor Blankenship Hall, 901 Woody Hayes Drive, Columbus, Ohio 43201-1189, Fax: (614) 688-3640. You will also need to provide a copy of the card to the Human Resources Officer for the department with which you are working.

Students must also go in person with their Social Security card to the Registrar's office to update their Social Security number in the student database.
