Look for your Social Security number on tax documents and bank or financial records. You can also contact your employer, who should have your number on file. If necessary, you can request a new Social Security card online.
You sit down to fill out a form and hit a snag: What's my Social Security number again? Forgetting a Social Security number (SSN) happens more often than you might imagine. It might not even be your number you need, but the one belonging to your child or a loved one. No matter the scenario, knowing how to find your SSN can help you save time and frustration.
There are a few ways you can find your SSN. Here are several places you can look, how to find it online and what to do if your SSN is stolen.
If you are unsure of your SSN, you may be able to verify the number by looking at certain documents, such as your:
If you've never been employed or paid taxes, you may not have a Social Security card. When you receive your first card, your name and nine-digit SSN are printed on its face. If you no longer have a card, you can request a new one online or through your local Social Security Administration (SSA) office.
Look for tax forms like an old tax return, W-2 or 1099 forms. These documents are usually provided by your employer. If you used a tax preparer, ask if they still have a copy on file. Unfortunately, the IRS generally won't give you your SSN over the phone or online for security purposes. Even if you request a tax transcript, only the last four digits of your SSN will be listed.
Old bank or brokerage statements may list your SSN, so it's worth combing through your paper documents or searching your online accounts. You may find it on a statement, document or annual tax form stored in your account. Financial institutions often don't include the full nine digits due to privacy concerns, but it's worth a look.
When you get a job, your employer must verify your SSN and make sure it matches your name so your earnings can be tracked for tax purposes. If other avenues to find your SSN have failed, call your employer's human resources or payroll department and explain the situation. They'll likely want to verify your identity before handing over your SSN, but it's one way to find your number without having to get a replacement card.

Short answer: You can't. The SSA website offers ways to get a replacement card but doesn't provide a way to look up your number. Increasingly, government agencies, companies and organizations no longer display your full nine-digit SSN online for your security.
If the methods above don't turn up your Social Security number right away, your surest bet is to go through the SSA to have a new card sent to you with your number.
Tip: The Social Security Administration also won't provide your Social Security number over the phone or via email.
You can request a replacement Social Security card online with the SSA by creating or logging in to your account. To be eligible for a new card, you must:
Online replacement is available in 43 participating states and Washington, D.C.
You can also call your local SSA office or 800-772-1213 for information on how to replace your card. If you go to your local office, it may be able to issue you temporary documentation verifying your SSN, which you can keep on hand while you wait for your new card to come in the mail.
You may not need to replace your Social Security card if you can remember your number. But if your card is lost or stolen and you're concerned your SSN may be compromised, consider taking some preventive steps to ensure someone else can't use your information to open accounts in your name.
Tip: Take steps to safely store your Social Security card. Keep the physical card at home in a secure place and avoid emailing or texting your SSN. If you need to share your SSN, use secure channels and ask the recipient how they protect your number.
