You can get a Social Security number for your newborn at the hospital, or apply afterward through your local Social Security office

The easiest path is to request a Social Security number when you fill out your baby's birth certificate at the hospital. Most hospitals have a form you complete during the first few days after birth, and you can check a box to request the number at the same time. The Social Security Administration (SSA) then processes it along with the birth certificate application, and you receive the number within a few weeks.

If you did not request it at the hospital, or if your state did not process it, you can apply at your local Social Security office. You will need to bring your baby's birth certificate, proof of your identity, and proof of your address. The process takes about two weeks once you submit the application in person.

You need a Social Security number to open a bank account for your child, claim them as a dependent on your taxes, enroll them in school, or apply for benefits. Even if you do not need one immediately, getting it early prevents delays later.

Requesting a number at the hospital

When you are filling out your baby's birth certificate paperwork in the hospital, you will see a section asking whether you want to request a Social Security number. Check yes, and the hospital will send that request along with the birth certificate application to your state's vital records office. The vital records office coordinates with the SSA to issue the number.

You do not need to do anything else at this stage. The hospital handles the paperwork, and you will receive the Social Security number in the mail within two to four weeks, usually printed on a card or in a letter from the SSA. Some states mail it directly to you; others send it to the hospital for you to pick up.

This method works in all 50 states and is the standard practice. If you are unsure whether you checked the box, contact your state's vital records office or the hospital where your baby was born — they can tell you whether the request was submitted.

Applying at a Social Security office if you missed the hospital window

If you did not request the number at the hospital, or if your state did not process it for some reason, you can apply directly at your local Social Security office. Call ahead or visit ssa.gov/locator to find the office nearest you and check their hours. Some offices require an appointment; others accept walk-ins during certain hours.

Bring these documents: your baby's birth certificate (original or certified copy), your own government-issued photo ID (driver's license or passport), and proof of your current address (utility bill, lease, or bank statement dated within the last 60 days). If you are applying on behalf of the child and are not the parent, bring a court order or guardianship papers.

The SSA will process your application on the spot and issue a Social Security number within about two weeks. You will receive it by mail. There is no fee for this service.

What happens after you receive the number

Once you have the Social Security number, keep it in a safe place. You will need it to file your taxes and claim your child as a dependent, which affects your tax refund. You will also need it to open a savings account or investment account for your child, enroll them in school, and apply for any government benefits they may be may have access to to.

Do not laminate the Social Security card or carry it in your wallet regularly. The card is fragile and can wear out. Store it at home in a secure location, and only bring it when you absolutely need to show it — for example, when opening a bank account or enrolling in school. Many institutions will accept a copy or just the number itself.

If your baby was born outside the United States

If your baby was born abroad and you are a U.S. citizen, you can still obtain a Social Security number. You will need to apply in person at a U.S. Social Security office or at a U.S. embassy or consulate in the country where your baby was born.

Bring your baby's foreign birth certificate, proof of U.S. citizenship for the child (such as a Consular Report of Birth Abroad or U.S. passport), and your own ID. The process is the same as applying domestically, and the number arrives within two to four weeks.

Replacing a lost or damaged Social Security card

If your child's Social Security card is lost, stolen, or damaged, you can request a replacement at your local Social Security office or online through ssa.gov/myaccount if you have set up an account. You will need to show your child's birth certificate and your own ID.

Replacements are free and arrive within one to two weeks. You can request up to three replacement cards per year. If you suspect the number has been used fraudulently, contact the SSA immediately and file a report with the Federal Trade Commission at identitytheft.gov.

Frequently Asked Questions

Can I get a Social Security number for my newborn before leaving the hospital?

You can request one during birth certificate registration at the hospital, but you do not receive the actual card or number before discharge. The hospital submits the request, and the SSA mails the number to you within two to four weeks. This is the standard process in all states.

What if I do not know my baby's Social Security number?

Contact your local Social Security office with your baby's birth certificate and your ID, and they can look it up for you. You can also call the SSA's main number at 1-800-772-1213 and provide your baby's name and date of birth, though they may ask you to visit an office to verify your identity before releasing the number.

Do I need a Social Security number to bring my newborn home from the hospital?

No. You can take your baby home without one. The number is useful for taxes, bank accounts, and school enrollment, but it is not required to leave the hospital or to care for your child at home.

What if the hospital lost my Social Security number request?

If you requested the number at the hospital but did not receive it after six weeks, contact your state's vital records office to confirm whether the request was submitted. If it was not, apply in person at your local Social Security office. If it was submitted but lost in processing, the SSA can reissue it.

Can someone else apply for my baby's Social Security number?

A parent or legal guardian can apply. If you are not the parent but are the legal guardian, bring court papers proving guardianship along with your ID and the baby's birth certificate. The SSA will not issue a number based on a verbal request from someone other than a parent or guardian.
