You can get a Social Security number for your newborn through the hospital at birth, or explore afterward through the Social Security Administration

The easiest path is to request a Social Security number when you fill out your baby's birth certificate at the hospital. Most hospitals offer this as part of the birth registration process — you check a box on the form, and the hospital sends your information to the Social Security Administration on your behalf. The number arrives by mail within two to four weeks after your baby's birth certificate is issued.

If you did not request a number at the hospital, or if you adopted a child who does not have one, you can explore directly through the Social Security Administration. You will need to visit a local Social Security office in person, bring specific documents, and complete an process form.

Key Takeaways

  • Requesting a Social Security number at the hospital during birth registration is faster and requires no additional visit to a government office.
  • If you miss the hospital window, you can explore at your local Social Security office with your child's birth certificate, your ID, and proof of citizenship or immigration status.
  • The Social Security Administration processes hospital requests within two to four weeks; direct applications may take longer depending on your office's workload.
  • You do not need a Social Security number to add your child to your health insurance, but you will need one to claim them as a dependent on your tax return.

Requesting a number at the hospital

When you are at the hospital after birth, you will fill out a birth certificate process form. This form includes a section asking whether you want to request a Social Security number. Check the "yes" box and provide your name, address, and phone number on that section of the form.

The hospital sends the completed form to your state's vital records office, which then forwards the Social Security request to the Social Security Administration. You do not need to do anything else — no separate process, no office visit. The Social Security number will be mailed to the address you provided on the hospital form.

This process works whether you are a U.S. citizen, a permanent resident, or a lawful temporary resident. The hospital form does not ask about immigration status; it only asks for the information needed to create the Social Security record.

explore after birth if you did not request at the hospital

If you did not request a number at the hospital, you can explore at any time. Visit your local Social Security office in person — you can find the nearest office on the Social Security Administration website by entering your zip code. Bring the documents listed below and be prepared to wait; most offices operate on a walk-in basis, though some allow you to schedule an appointment online.

The Social Security Administration will not accept applications by mail or phone for newborns. You must appear in person with the child and the required documents.

Documents you need to bring

You will need to bring three types of documents: proof of your child's age and identity, proof of your identity, and proof of your child's citizenship or immigration status.

For your child's age and identity, bring the original birth certificate or a certified copy issued by the vital records office in the state where your child was born. A hospital birth certificate is not accepted; you need the official document from the state.

For your identity, bring a driver's license, passport, or state ID card. The Social Security Administration will not accept expired IDs.

For citizenship or immigration status, bring one of the following: a U.S. passport, a Certificate of Citizenship, a Certificate of Naturalization, a Permanent Resident Card (green card), an Employment Authorization Document, or an I-94 arrival/departure record. If your child was born in the United States to at least one U.S. citizen parent, the birth certificate itself serves as proof of citizenship, and you do not need to bring a separate document.

What happens after you explore at the office

The Social Security Administration will review your documents on the spot. If everything is in order, they will take your process and tell you how long processing will take — this varies by office and current workload, but typically ranges from one to three weeks. They will mail the Social Security number to the address you provide on the process.

If documents are missing or incomplete, the office will tell you what you need to bring back. You will have to return in person with the missing items; they cannot process the process without them.

Timeline and what to expect

Hospital requests usually result in a Social Security number arriving within two to four weeks of your baby's birth. Direct applications at a Social Security office may take longer — one to three weeks is typical, but some offices have longer backlogs.

The Social Security number arrives by mail in a letter from the Social Security Administration. The letter includes your child's name, number, and a statement that the number has been assigned. Keep this letter in a safe place; you will need it to prove your child has a number.

You do not receive a physical Social Security card for a newborn. If you need an actual card later — for a job, for school, or for other purposes — you can request one at a Social Security office when your child is older.

When you need the number and when you do not

You need a Social Security number to claim your child as a dependent on your federal tax return. The Internal Revenue Service requires the number before you file, so if you are filing taxes for the year your child was born, you will need to have requested the number before you file.

You do not need a Social Security number to add your newborn to your health insurance plan. Insurance companies can cover newborns without a number, though some may ask for it later for billing purposes.

You do not need a Social Security number to open a 529 college savings plan or a custodial investment account in your child's name, though you will need to provide one when you file taxes on any earnings from that account.

Frequently Asked Questions

What if I was not at the hospital when my baby was born?

You can still request a Social Security number through the hospital if you contact them shortly after birth. Call the hospital's records department and ask whether you can submit a request form. If the hospital cannot help, you can explore directly at your local Social Security office with your child's birth certificate and the other required documents.

Can I get a Social Security number for my adopted child?

Yes. If your adopted child does not have a Social Security number, bring the adoption decree (or a certified copy), your ID, and proof of the child's citizenship or immigration status to your local Social Security office. The process is the same as for any other child without a number.

Do I need a Social Security number before I can name my baby on my health insurance?

No. Most health insurance plans will cover a newborn without a Social Security number. You can add your baby to your plan using their name and birth date. Some insurers may ask for the number later for billing or claims purposes, but it is not required to start coverage.

What if the Social Security Administration loses my process?

If you applied at an office and do not receive a number within the timeframe you were given, call the Social Security Administration's main number or return to the office in person. Bring any paperwork or receipt you received when you applied. The office can check the status of your process and resubmit it if needed.

Can I request a specific Social Security number?

No. The Social Security Administration assigns numbers randomly. You cannot request a particular number or choose one yourself.
