Request a Social Security Number for the First Time

What is a Social Security Number?

A Social Security number (SSN) is a unique identifier issued by the Social Security Administration. You need an SSN to work, and it’s used to determine your eligibility for Social Security benefits and certain government services.

Why might you need one?

Many financial institutions, such as banks and credit companies, also ask for your number when you open an account. If you are a noncitizen living in the United States, you may also need an SSN.

Tips for a successful application

All documents submitted must be either originals or certified copies by the issuing agency. We cannot accept photocopies or notarized copies of documents. You will need proof of U.S. citizenship and proof of identity to get a Social Security Card.

Please do not mail original primary documents that should be kept secure in your possession, such as driver’s licenses, passports, or immigration documents. Please call or visit your local Social Security office if you have questions.
