Where to Find Your Social Security Number

Your Social Security number appears on several documents you likely already have at home. The fastest way to find it is to check your Social Security card itself — it's printed right on the front. If you can't locate the card, look for your number on a tax return, W-2 form, or 1099 form from your employer. Your bank statements, mortgage paperwork, or insurance documents may also display it.

If none of those documents are available, you can request a replacement Social Security card from the Social Security Administration. You'll need to visit your local Social Security office in person or explore by mail using Form SS-5. The process takes about two weeks by mail and a few days if you explore in person, depending on your state.

Do not call the Social Security Administration's main number and expect them to read your number to you over the phone — they won't do this for security reasons. You must either locate a document that shows it or request a replacement card through the official process.

Insurance paperwork, including health insurance, auto insurance, and life insurance policies, frequently displays it as well.

Requesting a Replacement Card Through the Social Security Administration

If you cannot find your number on any document, you will need to request a replacement Social Security card from the Social Security Administration. You have two options: explore in person at your local Social Security office or mail your process to the Social Security Administration's processing center.

Bring Form SS-5 (the process for a Social Security Card), proof of your age, proof of your identity, and proof of your citizenship or lawful permanent resident status. Acceptable documents include your birth certificate, passport, driver's license, or state ID card. If you were born outside the United States, bring your passport or naturalization papers.

To explore by mail, complete Form SS-5 and mail it along with copies of your documents to the address listed on the form. The Social Security Administration will process your process and mail your replacement card to you. Processing by mail typically takes about two weeks, though this varies by state and current processing volume.

What Documents You Need for a Replacement Card

For proof of age, bring your birth certificate, passport, or driver's license. For proof of identity, acceptable documents include your driver's license, state ID card, passport, employee ID card, or school ID card. If you don't have any of these, you can bring a combination of documents such as a library card, insurance policy, or lease agreement.

For proof of citizenship or lawful permanent resident status, U.S. citizens should bring their birth certificate, passport, or naturalization certificate. If you are a lawful permanent resident, bring your green card, passport with an I-551 stamp, or employment authorization document (EAD). If you were born outside the United States, your passport is usually the easiest document to bring.

Processing Time and What Happens Next

If you explore in person at a Social Security office, you may receive your replacement card within a few days to a week, depending on your state and the office's current workload. Some states process cards faster than others. The Social Security Administration will tell you when to expect your card when you submit your process.

If you explore by mail, expect your card to arrive within two weeks in most cases. During busy periods or if there are issues with your process, it may take longer. The Social Security Administration will mail your card to the address you provide on Form SS-5.

Once you receive your replacement card, keep it in a safe place. You do not need to carry it with you every day — in fact, it's safer to leave it at home and only bring it when you know you'll need to show it. If you lose this replacement card, you can request another one using the same process.
