Get your SSN

A Social Security Number (SSN) is a nine-digit number issued by the US Social Security Administration (SSA). SSA created it in 1936 to track earnings for retirement benefits. Today the US uses it as the main identity number for adults. Your taxes sit on top of it. Your credit file is keyed to it. Your employer reports your wages against it. Most federal benefits you may later qualify for are tied to it.

Two things are worth knowing before you apply. Your SSN is for life. You get one number and you keep it forever, so you do not get a new one because you moved, switched visas, or changed your name. The card itself is a small paper card and nothing more. The number is what counts, and most of the time you type it into a form rather than show the card.

SSA issues the SSN, not US Citizenship and Immigration Services (USCIS) and not the Internal Revenue Service (IRS). If you are not eligible for an SSN but still owe US taxes, the IRS issues an Individual Taxpayer Identification Number (ITIN) instead. An ITIN covers tax filing only. It is not work authorization, and it does not replace an SSN for banking or credit.

Anyone who is work-authorized in the US can get an SSN. That covers US citizens, green card holders, and most nonimmigrants whose status carries work authorization automatically (H-1B, L-1, O-1, TN, J-1 with a sponsor letter, asylees, refugees). It also covers anyone holding a separate Employment Authorization Document (EAD, Form I-766) from US Citizenship and Immigration Services (USCIS).

Some statuses need a prerequisite in place first. F-1 students need an on-campus job offer plus a letter from their Designated School Official (DSO) before SSA will process the application. J-1 exchange visitors in the Student, Student Intern, or International Visitor categories need a sponsor letter from their Responsible Officer (RO). H-4, J-2, Temporary Protected Status (TPS), and asylum-pending applicants need the physical EAD card in hand, not just the approval notice.

Other statuses are not eligible for an SSN at all: B-1/B-2 tourists, ESTA visitors, F-2 dependents, and similar. Those applicants can still file US taxes with an Individual Taxpayer Identification Number (ITIN), and SSA will issue an official ineligibility letter (Form SSA-L676) that most Department of Motor Vehicles (DMV) offices accept in place of an SSN for a state ID.

Which rules apply to you depends on your visa, your work basis, and sometimes your state. SettleKit works out which ones apply to you and what step comes next.

An SSN runs through most of the US financial and tax system. It shows up in four places, in rough order of urgency.

Employment

Your employer puts your SSN on your Form W-2 to report your wages. On Form I-9, the employment eligibility form you complete when you start a job, the SSN field in Section 1 is voluntary unless your employer uses E-Verify. You do not need an SSN, or an SSA receipt, to begin work: no provision in the Social Security Act prohibits an employee from beginning work before obtaining an SSN. Give your employer the number as soon as the card arrives so payroll and your Form W-2 are correct.

Banking

Large US banks ask for an SSN to open interest-bearing accounts and to satisfy customer-identification rules under the Bank Secrecy Act. Not every bank requires one. SettleKit's bank-account guide lists the providers that accept your status, so you can open an account while your SSN application is still running.

Credit

Credit bureaus build your credit file against your SSN. A first credit card, auto loan, or apartment lease in the US needs either an SSN plus six months of on-time payments to generate a FICO credit score, or a newcomer program that imports your foreign credit history, such as American Express Global Transfer or Nova Credit.

Taxes

The Internal Revenue Service (IRS) expects an SSN on Forms W-2 and 1040. Without one you file with an ITIN. That is legal and common, but it is slower and it qualifies you for fewer tax credits.

SSA accepts only original, unexpired documents. Photocopies, notarized duplicates, and photos on your phone are turned away at the counter. Every applicant has to prove three things: identity, age, and lawful status or work authorization.

For most work-authorized nonimmigrants, the stack looks like this:

• An unexpired foreign passport, which covers identity and age
• Your most recent Form I-94 Arrival/Departure Record, printed from i94.cbp.dhs.gov
• One status document: an Employment Authorization Document (Form I-766), a Form DS-2019 (J-1), a Form I-20 plus employment letters (F-1 on-campus), or the approval notice for your specific status

F-1 students applying for an on-campus SSN need two extra pieces: a wet-signed employment letter from the hiring department, and a letter from the Designated School Official (DSO). J-1 exchange visitors whose DS-2019 lists the category Student, Student Intern, or International Visitor need an original, wet-signed Responsible Officer (RO) sponsor letter on top of the DS-2019. H-4, J-2, and asylum-pending applicants need the physical EAD card. A Form I-797 approval notice by itself will be turned away at the counter.

The exact combination depends on your visa and work basis. Signatures follow their own rules, and they are not all the same. SSA accepts a digitally signed DS-2019: the US Department of State approved electronic signing for exchange visitor sponsors in 2023, and SSA told its field offices to accept it. SSA also accepts three digital methods on the Form I-20, set out in its Program Operations Manual System (POMS) at RM 10211.275B: a scan of a physically signed form, a form signed with software such as Adobe, and a form carrying a digitally reproduced copy of a physical signature. The RO sponsor letter and the campus employment letter still need wet ink.

The application is Form SS-5. You can fill it out in two ways:

1. Start online. Most applicants can begin on SSA's online application portal. It asks the same questions as the paper form and gives you an Online Control Number at the end. Save that number. At the SSA office it replaces the paper form entirely.
2. Do it on paper. If online will not work for your case, because you have no US mailing address yet, or the portal stops you with a validation error, print Form SS-5, fill it out, and sign it in wet ink.

Three details cause most of the trouble. Your name on Form SS-5 has to match your passport exactly, middle names and all. Your mailing address decides where the card goes 2 to 4 weeks later, so check the apartment or unit number: a missing unit number sends the card back to SSA undelivered. Commercial mailbox addresses, such as a UPS Store or a mailbox service, get flagged by SSA and the card will not be mailed there. Use a real residential address, an employer address, or the address of a friend you trust who lives somewhere stable.

The application is free. SSA charges nothing. Any website asking you to pay for Form SS-5 is a third-party reseller, not SSA.

SSA checks your status against a federal database called Systematic Alien Verification for Entitlements (SAVE), which pulls from the Department of Homeland Security (DHS). SAVE is not instant. If you walk into an office the day after you arrive, verification either fails outright or starts a manual review that can push your card out by weeks.

International student offices publish the same guidance: wait at least 10 days after entering the US before applying, and, for F-1, M-1, and J-1, make sure your Student and Exchange Visitor Information System (SEVIS) record has been active for at least 2 days. When both conditions are true, SAVE can confirm you and SSA issues the number on the usual 2 to 4 week timeline.

There is an upper bound on the other side. F-1 on-campus and Curricular Practical Training (CPT) applicants can apply up to 30 days before the job start date. J-1s with a valid sponsor letter can apply as soon as SEVIS clears. Optional Practical Training (OPT) and M-1 EAD holders have to wait for the exact start date printed on the EAD. Applying a day early comes back as not authorized and you are turned away.

If you started the application online, SSA gives you 45 days from the application date to appear in person. Miss that window and the Online Control Number expires, and you start over.

For most applicants the flow goes like this:

1. Confirm eligibility. Check that your visa and work basis put you in an SSN-eligible status, and that any prerequisite is done: the EAD card in hand, the Designated School Official (DSO) letter, or the Responsible Officer (RO) sponsor letter.
2. Gather your originals. Bring your passport, your Form I-94 printout, and whichever status documents apply to you: EAD, DS-2019, I-20, or employment letters.
3. Start Form SS-5 online. Complete it on SSA's portal and save the Online Control Number you get at the end.
4. Book the in-person appointment. Since 23 February 2026, when the online application cannot finish your case fully online, it redirects you straight into SSA's appointment scheduling system. You have 45 days from the date of the application to appear in person, so screenshot your Online Control Number and book early. Plan on 1 to 2 hours on site.
5. Hand over your documents. The clerk verifies them through the Systematic Alien Verification for Entitlements (SAVE) database, confirms your identity, and keys your details into the system. Watch what they type. A wrong letter is fixable later, but catching it at the counter saves you a second visit.
6. Leave with a receipt. You walk out with confirmation that the application is filed. SSA prints and mails the card separately.

The application is free. You never pay SSA, and you do not need a lawyer, a translator, or a paid service to file it.

Use the official SSA Office Locator to find a Social Security field office near you. Enter your ZIP code and it returns the closest offices with hours, phone numbers, and whether they take walk-ins or require an appointment.

Offices differ a lot in how long you wait. If the office nearest you is booked out for weeks, any SSA office in the country can take your application, so driving to the next town over is a real option and often a faster one.

One detail catches people out. SSA processes your application at the local office, but the card is printed and mailed from a central facility. It goes to the address on your Form SS-5, not to the office you visited. If you know your address is changing in a few weeks, wait and apply from the stable address. United States Postal Service (USPS) forwarding of an SSN card is unreliable, and SSA does not re-send to a forwarded address.

Your employment basis changes the sub-rules.

F-1 on-campus employees need a wet-signed job offer letter from the hiring campus department plus a letter from their Designated School Official (DSO) confirming enrollment. You can apply up to 30 days before your start date, which matters because orientation-week hiring is normal. F-1 Optional Practical Training (OPT) and STEM OPT applicants have to wait for the exact start date printed on the EAD card, and applying a day early is refused. F-1 Curricular Practical Training (CPT) applicants apply with a CPT-endorsed Form I-20, using the page 2 endorsement from the DSO, up to 30 days before the CPT start date.

J-1 exchange visitors should look at Item 4 of the DS-2019. If it reads Student, Student Intern, or International Visitor, SSA requires a wet-signed Responsible Officer (RO) sponsor letter on top of the DS-2019.

H-1B, L-1, O-1, and TN workers have no prerequisites. Apply as soon as the 10-day SAVE window has passed. H-4, J-2, asylum-pending, and Temporary Protected Status (TPS) applicants need the physical EAD card in hand. A USCIS approval notice (Form I-797) alone is not accepted at the counter.

If an SSA clerk says a document is wrong and you are sure it is not, stay polite and ask them to check the rule. Clerks give incorrect guidance on rarer international cases. SSA publishes the rules in its Program Operations Manual System (POMS), and quoting the section that governs your case can settle the question at the counter. POMS RM 10211.205 covers evidence of asylee status, and its subsection D covers applicants who have applied for asylum but have not been granted it. POMS RM 10211.250 covers the DSO letter and employment letter for F-1 on-campus work. Bookmarking the one that fits your case takes two minutes.

After SSA accepts your application and SAVE clears your status, printing and mailing the card takes 2 to 4 weeks. SSA publishes a shorter figure for a straightforward case, 10 business days, in POMS RM 10211.290. Systematic Alien Verification for Entitlements (SAVE) checks on noncitizens add time on top of that, and appointment waits at busy field offices add more.

SSA does not offer online tracking for Form SS-5 applications. If four weeks have gone by and nothing has arrived, call SSA at 1-800-772-1213 to check the status, or return to the office with your receipt. If the card was mailed but USPS sent it back, because mail forwarding was active, the unit number was missing, or your name was not on the mailbox, the application has to be reopened so SSA can reissue it.

Timing matters for what comes next. Plenty of banks open an account on a passport plus a visa while your SSN application is still running, so the wait does not block everything. Lenders, landlords, and state Department of Motor Vehicles (DMV) offices ask for the number, so the rest of your setup moves faster with the card in hand.

The card arrives by regular United States Postal Service (USPS) mail. There is no tracking and no signature on delivery. It is a small paper card, not plastic, and the back has a line asking you to sign it in ink.

Do three things on the day it arrives. Photograph both sides and store the image somewhere encrypted, such as a password manager, because you will need the number far more often than the physical card. Put the card in a safe, a locked drawer, or a safety deposit box, and keep it out of your wallet. Check the name, date of birth, and number against your passport, and if anything is wrong, call SSA at 1-800-772-1213 and ask to correct the record.

If the card has not arrived after four weeks, the two usual causes are a mailing-address problem, such as a missing unit number, a name not on the mailbox, or a commercial mailbox SSA flagged, or a SAVE verification that is still running behind the scenes.

Your SSN is one of the most valuable pieces of information a scammer can get hold of. Four rules keep it safe.

Leave the card at home once you know the number. Do not carry it in your wallet, and do not hand the number out casually. The parties with a legitimate reason to ask are employers, banks, the Internal Revenue Service (IRS), lenders running a credit check, landlords running tenant screening, and state Department of Motor Vehicles (DMV) offices. If anyone else asks for it, ask what they need it for and whether a different ID will do. Often it will.

Treat any unexpected phone call about your SSN as a scam. SSA will never call you to say your SSN has been suspended, demand payment in gift cards, or ask you to verify the number. Hang up, then report the call at oig.ssa.gov.

Create a my Social Security account at ssa.gov/myaccount. Claiming the account under your own login stops a scammer from creating one in your name.

Put a credit freeze on all three bureaus: Equifax, Experian, and TransUnion. A freeze is free, takes a few minutes, and stops most new-account fraud.

If you suspect your SSN has already been exposed, the Federal Trade Commission (FTC) runs identitytheft.gov, which builds you a recovery plan step by step.

Here are the SSN problems that come up most, and what fixes them.

The card never arrived

Call SSA at 1-800-772-1213 after four weeks. The usual causes are an incomplete mailing address, such as a missing apartment number, or an address SSA flagged as a commercial mailbox. SSA reissues the card to a corrected address, and a card you never received does not count against your replacement limit.

The details on the card are wrong

Take the card and your passport to a field office. If SSA can see the keying error in your application, the office corrects the record itself using Numident Correction Processing, and the correction does not count against your card limits. If no keying error is on file, you file a new Form SS-5 at a field office with documents that support the correct name or date of birth. There is no separate central office to escalate to.

Lost or stolen card

Request a replacement through ssa.gov/number-card. Replacements are free. SSA limits them to 3 per year and 10 in a lifetime, and past those limits SSA denies the application rather than charging a fee. Cards issued for a legal name change or a legend change do not count toward the limits, and neither do replacements for a card you never received, an SSA error, or a documented hardship. The number never changes. In most cases you do not need a new card at all, because what you need is the number and you already have it written down.

You are not eligible and need an ineligibility letter

Most Department of Motor Vehicles (DMV) offices accept Form SSA-L676, SSA's official ineligibility letter, in place of an SSN for a state ID or driver's license. Apply for it the same way as an SSN. SSA reviews your documents at the field office and issues the letter when it cannot issue a number.

Your status needs an extra letter or an extra step

A clerk refusing a valid document, a mismatch between your I-94 and your EAD, or a category that needs a sponsor letter comes up often enough that SettleKit builds the recovery path for your situation into the in-app steps.
