You cannot look up your Social Security number online through a government website

The Social Security Administration does not offer a tool where you can enter your name and get your number back. There is no SSN lookup database open to the public, and no official government website will retrieve it for you. If you have lost track of your number, you will need to contact SSA directly or find it on documents you already have.

This matters because scammers often pose as SSA and claim to offer online lookup tools. They do not. Any website promising to find your SSN online is either collecting information for identity theft or selling your data to someone who will.

Key Takeaways

  • Your Social Security number appears on your Social Security card, tax returns, W-2 forms, and bank statements — checking these first is faster than contacting SSA.
  • You can call the Social Security Administration at 1-800-772-1213 (TTY 1-800-325-0778) to request your number, but you will need to verify your identity with personal details.
  • You can visit a local Social Security office in person with a photo ID and birth certificate to request your number or a replacement card.
  • Never enter your Social Security number into a website that claims to look it up for you — legitimate SSA services do not work that way.

Check documents you already have at home

Your Social Security number is printed on several documents most people keep. Start here before contacting SSA, because you may find it in minutes.

Look for your original Social Security card in a safe place, a drawer, or with important documents. If you have filed taxes, your number appears on every tax return you submitted — check old returns or contact your tax preparer. Your W-2 forms from employers also show your SSN. Bank statements, mortgage papers, and investment account statements all list it. If you have ever applied for a loan or credit card, the approval letter or statement will have your number.

If you have a spouse or parent who might have a copy of your birth certificate or early medical records, ask them — some people keep family documents together. Your employer's human resources department may also have your SSN on file from your hiring paperwork.

Call the Social Security Administration directly

The fastest way to reach SSA is by phone. Call 1-800-772-1213 (TTY 1-800-325-0778 for people who are deaf or hard of hearing). The line is open Monday through Friday, 7 a.m. to 7 p.m. your local time. Wait times are usually shorter early in the morning or late in the afternoon.

When you call, have your birth certificate, driver's license or passport, and proof of address ready. SSA will ask you questions only you should know — your mother's maiden name, previous addresses, or details from your work history — to confirm your identity before they tell you your number. They will not ask for your number itself during this call.

The representative can also tell you if a replacement card is on the way or if you need to request one. If you need a new card, they can start that process over the phone in most cases.

Visit a Social Security office in person

If you prefer to handle this face-to-face, you can go to your local Social Security office. Bring a photo ID (driver's license, passport, or state ID) and your birth certificate. You do not need an appointment at most offices, but you can schedule one online at ssa.gov to avoid a wait.

The office staff will verify your identity and provide your Social Security number on the spot. If your card is lost or damaged, they can order a replacement at the same visit. Replacement cards usually arrive within 7 to 10 business days. You are may have access to to three free replacement cards per year and unlimited replacements after that if you have a legitimate need.

To find the office nearest you, go to ssa.gov, click "Locations," and enter your zip code. The website shows hours, phone numbers, and whether walk-ins are accepted.

Understand why SSA does not offer online lookup

The Social Security Administration keeps your number private by design. If anyone with your name and birth date could look up your SSN online, identity thieves could do the same. SSA requires you to prove who you are — either by phone with personal questions or in person with documents — before releasing your number.

This is why any website claiming to look up SSNs online is a red flag. Legitimate government services require identity verification, not just a form submission. If a site asks for your SSN to find your SSN, it is a scam.

What to do if you suspect identity theft

If you lost your Social Security card or suspect someone has your number, contact SSA right away. Call 1-800-772-1213 or visit your local office. SSA can flag your account and issue you a new number if needed, though getting a new SSN is uncommon and only done in cases of serious fraud.

You should also place a fraud alert with the three major credit bureaus — Equifax, Experian, and TransUnion — by calling any one of them. They will notify the others. A fraud alert tells creditors to verify your identity before opening new accounts in your name. You can also freeze your credit for free, which blocks access to your credit report entirely until you unfreeze it.

Frequently Asked Questions

Can I look up someone else's Social Security number?

No. SSA will only release a Social Security number to the person it belongs to, and only after they verify their identity. You cannot look up another person's SSN, even a family member, without their permission and presence.

What if I do not have a birth certificate or photo ID?

Call SSA at 1-800-772-1213 and explain what documents you do have. They can sometimes verify your identity using other information, like previous addresses or employment history. You may need to visit an office in person with whatever ID you do have and explain the situation to a representative.

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

Standard replacement cards arrive within 7 to 10 business days. Some offices offer expedited service for an additional fee. Ask when you request the card whether faster options are available in your area.

Is there a fee to get my Social Security number or a replacement card?

No. The Social Security Administration does not charge for Social Security cards or for telling you your number. If someone asks for payment, it is not SSA.

What should I do if a website asks for my Social Security number to "verify" it?

Do not enter it. Legitimate SSA services verify your identity through questions and documents, not by asking you to type your SSN into a website. Close the site and contact SSA directly using the phone number or office address you find on ssa.gov.
