How to Get Your Social Security Number (SSN) in the United States
A practical, step-by-step guide to getting a Social Security Number (SSN) in the United States as a newcomer: who is eligible, the documents you need, how to
What the SSN is and why you need it
A Social Security Number (SSN) is a nine-digit number issued by the U.S. Social Security Administration (SSA) that follows you for life. Although it was created to track earnings for Social Security benefits, it has become the closest thing the United States has to a national identity number. You will need it to work legally and have your wages reported, to file federal and state taxes, to open most bank accounts, to build a credit history, and often to rent an apartment, set up utilities or get a phone contract. For newcomers, getting an SSN as soon as you are eligible removes friction from almost every part of settling in, so it should be one of your first administrative tasks after arrival.
Who is eligible for an SSN
In general, you are eligible for an SSN if you are authorized to work in the United States. This includes lawful permanent residents (green card holders) and people on work-authorized visas such as H-1B, L-1, O-1, or those with an Employment Authorization Document (EAD). If you are not authorized to work, you usually cannot get an SSN; instead you may need an Individual Taxpayer Identification Number (ITIN) from the IRS for tax purposes. Some non-working dependents who need a number for a specific federal or state benefit may qualify in narrow cases. Your immigration documents determine your eligibility, so it helps to understand your visa category before you apply.
Documents you will need
The SSA requires original documents or copies certified by the issuing agency; photocopies and notarized copies are not accepted. You will typically need proof of identity and immigration status, such as your passport, visa, and Form I-94 arrival/departure record, plus your work authorization where relevant (for example your EAD or the I-797 approval notice for your visa). Lawful permanent residents show their green card. Documents must be current and unexpired. If your name has changed, bring evidence such as a marriage certificate. Gathering everything before your visit prevents a second trip, since the office will not process an incomplete application.
How to apply step by step
Most newcomers apply by completing Form SS-5, the Application for a Social Security Card, which is free to file. You can often start by printing or filling the form online, then submitting it in person at your local Social Security office along with your original documents. Some categories of immigrants can request an SSN as part of the visa application process abroad (through the DS-260 immigrant visa form), in which case the card is mailed automatically after arrival. There is never a fee to apply for or replace an SSN card, so be wary of anyone who asks you to pay for one. Booking an appointment, where available, reduces waiting time.
After you apply: timing and the card
Once your application is accepted, the SSA verifies your immigration documents with the Department of Homeland Security, which can add time for recent arrivals whose records may not yet be in the system. The physical Social Security card is usually mailed to your U.S. address within about two weeks after your documents are verified, though it can take longer if verification is delayed. Keep the card in a safe place rather than your wallet, because it is a sensitive document. Memorize the number, and only share it when truly necessary, such as with your employer, bank, or tax authorities, to reduce the risk of identity theft.
Common pitfalls and tips for newcomers
A frequent mistake is applying too soon after arrival, before your entry record has been transmitted to the SSA, which can cause your application to be rejected; waiting a couple of weeks after entering the country often helps. Another is assuming you cannot start work without the card in hand, when in fact employers can generally let you begin while your SSN is pending, as long as you have work authorization. Protect your number carefully, never carry the card daily, and never pay a third party to obtain it. If you change address while waiting, tell the SSA so your card is delivered correctly, and follow up at your local office if it does not arrive within a few weeks.
Frequently asked questions
How much does it cost to get an SSN?+
Nothing. Applying for an original Social Security card, replacing a lost one, or correcting it is always free through the Social Security Administration. There is no government fee at any stage, so never pay a third party who claims they can get you a number faster.
How long does it take to receive the card?+
After your documents are verified, the card is usually mailed to your U.S. address within about two weeks. For recent arrivals, verification with immigration records can add time, so applying a couple of weeks after entry and confirming your address are accurate helps avoid delays.
Can I work while my SSN application is pending?+
Generally yes, if you are authorized to work. Employers can usually let you start while your SSN is being processed, as long as you have valid work authorization. You provide the number to your employer once you receive it so your wages can be reported correctly.
What if I am not authorized to work in the US?+
If you are not authorized to work, you usually cannot get an SSN. For tax filing or certain financial needs, you may instead apply for an Individual Taxpayer Identification Number (ITIN) from the IRS, which is used for tax purposes but does not grant work authorization.
Do I need to apply in person?+
Many applicants apply in person at a local Social Security office with their original documents. Some immigrants can request the SSN abroad during the immigrant visa process, in which case the card arrives by mail automatically. Check your category and book an appointment where possible.
