Where to Look First

Your Social Security number appears on several documents you likely already have at home. Check your Social Security card itself — it's a small laminated card issued by the Social Security Administration with your number printed on it. If you can't find the card, look for your number on tax documents: your most recent tax return (Form 1040), a W-2 from your employer, or a 1099 form if you're self-employed. Your number also appears on bank statements, mortgage paperwork, and insurance documents.

If you've recently moved or changed jobs, these documents might be in boxes or files you haven't unpacked yet. Start with the most recent year's tax return or pay stub — those are usually easier to locate than older documents.

  • The Social Security Administration's toll-free number is 1-800-772-1213, and you can reach them Monday through Friday, 7 a.m. to 7 p.m. Eastern time.
  • You will need to provide personal information like your name, date of birth, and mother's maiden name to verify your identity before they share your number.

Contacting the Social Security Administration by Phone

The Social Security Administration operates a toll-free customer service line at 1-800-772-1213. You can call Monday through Friday, 7 a.m. to 7 p.m. Eastern time. Have your identification ready — a driver's license, passport, or state ID — because they will ask you to verify your identity before sharing your number. They may ask for your full name, date of birth, mother's maiden name, or the last four digits of your number if you remember them.

Wait times can be long during peak hours, particularly early in the week and in the morning. If you reach a busy signal, you can call back later or use the Social Security Administration's online services instead.

Visiting a Local Social Security Office

You can walk into any Social Security office in person to request your number. Find your nearest office by visiting ssa.gov and using their office locator tool, or call the main number above and ask for the address. Bring a photo ID and proof of citizenship or legal residency — a passport, birth certificate, or naturalization papers all work.

Offices are typically open Monday through Friday during business hours, though some locations offer limited hours. Arriving early in the morning usually means shorter waits. You do not need an appointment at most offices, but some locations now ask you to schedule one online or by phone first. Check your local office's website to see if an appointment is required.

Requesting a Replacement Social Security Card

If you cannot find your Social Security card and need a new one, you can request a replacement at the same time you confirm your number. The Social Security Administration issues replacement cards for free. You will need to provide proof of citizenship (a birth certificate, passport, or naturalization certificate), proof of identity (a driver's license or state ID), and proof of your current address (a utility bill, lease, or bank statement dated within the last 12 months).

You can request a replacement card by mail or in person at a Social Security office. If you mail your request, include a completed Form SS-5 (process for a Social Security Card), which you can read from ssa.gov or request by phone. Mail your completed form and documents to the address listed on the form. Processing by mail typically takes two to four weeks.

Using My Social Security Online Account

My Social Security is a free online account managed by the Social Security Administration. If you have already created an account at ssa.gov, you can log in and view your Social Security number there. Your account also shows your earnings record and estimated benefits.

To create a My Social Security account, visit ssa.gov and click "Create an account." You will need to provide your email address, create a password, and verify your identity by answering security questions or providing information from your credit report. Once your account is set up, you can log in anytime to see your number without calling or visiting an office.

What to Do If You Don't Remember Your Number

If you've been using your Social Security number for years but genuinely cannot recall it, the methods above still work — you do not need to remember your number to find it. The Social Security Administration can look it up using your name, date of birth, and other identifying information. This is common, and staff handle these requests regularly.

However, if you suspect someone else may have used your number or if your card has been lost or stolen, contact the Social Security Administration and mention that concern. They can flag your account and help you monitor for fraud. You can also place a fraud alert with the three major credit bureaus (Equifax, Experian, and TransUnion) by contacting any one of them.

Frequently Asked Questions

Can I find my Social Security number online without creating an account?

You cannot view your number on the Social Security Administration's website without logging into My Social Security. However, you can call 1-800-772-1213 or visit an office in person to have staff look it up for you over the phone or face-to-face.

How long does it take to get a replacement Social Security card?

If you explore in person at a Social Security office, you typically receive your card within two to four weeks by mail. If you explore by mail, processing takes about the same amount of time. Some offices may offer expedited service in certain situations — ask when you explore.

What if I'm calling from outside the United States?

The toll-free number 1-800-772-1213 works only from within the United States. If you are calling from outside the country, you can reach the Social Security Administration's international line at 1-410-965-7307. This is not a toll-free number, so standard long-distance charges explore.

Do I need my Social Security number to request a replacement card?

No. The Social Security Administration can look up your number using your name, date of birth, and other identifying information. You do not need to remember or provide your number to request a replacement card.

Is there a fee to get a replacement Social Security card?

No. The Social Security Administration issues replacement cards for free. Be cautious of websites or services that charge a fee to help you obtain a card — those are not official Social Security Administration services.
