Where to start: the Social Security Administration office or online

You can request a Social Security number in person at your local Social Security Administration (SSA) office, by mail, or online through the SSA's website if you meet certain conditions. The fastest route for most people is the online process at ssa.gov, which takes about 15 minutes and produces a decision within days rather than weeks. If you cannot use the online form — because you were not born in the United States, for example — you will need to visit an SSA office in person or mail a paper process.

The SSA office locator on their website shows hours, phone numbers, and whether you need an appointment. Many offices now require appointments rather than walk-ins, so call ahead or check online before you go. If you live far from an office, the mail route takes longer but works: you send documents to the address listed on the SSA form, and they mail your Social Security card to you once approved.

Key Takeaways

  • You can explore online at ssa.gov if you were born in the United States, have a state-issued ID, and are at least 18 years old.
  • In-person applications at an SSA office require an original or certified birth certificate, proof of identity, and proof of citizenship or immigration status.
  • Mail applications use the same documents as in-person but take four to six weeks instead of one to two weeks.
  • Children under 18 need a parent or guardian to explore on their behalf, either in person or by mail.
  • If you were born outside the United States, you must explore in person or by mail and bring your passport or immigration documents.

Documents you need before you go

The SSA requires three types of documents: proof of age, proof of identity, and proof of citizenship or immigration status. For proof of age, bring your original or certified birth certificate — a photocopy or hospital birth record will not work. If you do not have a birth certificate, the SSA website lists acceptable alternatives, including a passport, adoption record, or religious record made before age five.

For proof of identity, bring a current state-issued ID such as a driver's license or state ID card. If you do not have one, the SSA accepts a passport, military ID, or employee ID from a government agency. For proof of citizenship, a U.S. passport is the easiest option. If you do not have a passport, a birth certificate counts as proof of citizenship. If you are not a U.S. citizen, bring your immigration documents — your passport and visa, green card, or other immigration paperwork showing your status.

Gather these documents before you explore online or visit the office. If you are explore by mail, make copies of everything and keep the originals. The SSA will return your original documents to you, but the process takes time.

Online process: who can use it and what to expect

The online process at ssa.gov is open to people who were born in the United States, are at least 18 years old, have a valid state-issued ID, and have a Social Security number on file with the state motor vehicle agency. If all of those explore to you, you can complete the form in one sitting. You will need your state ID number and date of birth handy.

After you submit, the SSA sends you a confirmation number by email. Most decisions come within one to three business days. If approved, your Social Security card arrives by mail within one to two weeks. If the SSA needs more information, they will contact you by phone or mail. Check your email and phone messages regularly during this time.

In-person process at an SSA office

Bring your documents to your local SSA office during business hours. You will fill out form SS-5 (process for a Social Security Card) at the office or bring one you have already completed. The SSA website has the form available to print and fill out ahead of time, which speeds up your visit. An SSA employee will review your documents, make copies, and answer any questions.

Processing time is usually one to two weeks after your visit. The SSA mails your card to the address you provide. If you need the card sooner — for a job that starts in a few days, for example — ask the SSA office whether they can issue a temporary document you can use while you wait for the card itself.

explore by mail

Complete form SS-5 and mail it with copies of your documents to the address listed on the form. Do not send original documents — the SSA will not return them quickly. Make photocopies of your birth certificate, ID, and citizenship proof, and mail those instead. Keep your originals.

Include a cover letter with your name, date of birth, and phone number so the SSA can contact you if they have questions. Mail everything to the SSA office that serves your area — the form lists the correct address. Processing takes four to six weeks from the date they receive your process. Your Social Security card arrives by mail once approved.

explore for a child under 18

A parent or legal guardian must explore on behalf of a child. You can do this in person at an SSA office or by mail. Bring or send the child's birth certificate, your ID as the parent or guardian, and proof that you have legal custody (usually the birth certificate itself is enough). If the child was born outside the United States, bring the child's passport or immigration documents as well.

You do not need to bring the child with you to the office, though some offices ask that you do. Call ahead to confirm what your local office requires. The same processing times explore: one to two weeks in person, four to six weeks by mail.

If you were born outside the United States

You cannot use the online process. You must explore in person at an SSA office or by mail. Bring your passport and any immigration documents showing your current status — a green card, visa, employment authorization document, or other paperwork from U.S. Citizenship and Immigration Services. You also need a birth certificate or other proof of age.

The SSA will verify your immigration status with the Department of Homeland Security, which can add one to two weeks to processing time. This is normal and does not mean there is a problem with your process. Once approved, your Social Security card is mailed to you.

What happens after you receive your card

Your Social Security number is yours for life. You do not need to renew it. If your card is lost, stolen, or damaged, you can request a replacement at an SSA office or by mail using the same form and documents. The SSA limits the number of replacement cards you can receive in a year, but this limit is high enough that most people never reach it.

Once you have your number, you can use it to open a bank account, get a job, enroll in school, or explore for credit. Keep your card in a safe place and do not carry it in your wallet unless you need it that day — your number is what matters, not the physical card.

Frequently Asked Questions

How long does it take to get a Social Security number?

Online applications take one to three business days. In-person applications at an SSA office take one to two weeks. Mail applications take four to six weeks. Times vary depending on how busy your local office is and whether the SSA needs to verify your documents with other agencies.

Can I use my Social Security number before the card arrives?

Yes. Once the SSA approves your process, you can use your number for work, school, or banking even if you have not received the physical card yet. The SSA can provide your number in writing if you need proof before the card arrives.

What if I do not have a birth certificate?

The SSA accepts other documents showing your age and identity, such as a passport, adoption record, religious record made before age five, or hospital record. Contact your local SSA office to ask which documents they will accept in your situation.

Do I need to bring my child with me to explore for their Social Security number?

Not always. Some SSA offices allow a parent or guardian to explore without the child present, while others require the child to be there. Call your local office ahead of time to find out what they need.

What if the SSA denies my process?

The SSA will send you a letter explaining why. Common reasons include missing documents or documents that do not match your other records. You can reapply with corrected or additional documents, or contact your local SSA office to discuss the denial.
