Request SSN

A Social Security Number (SSN) is a nine-digit number issued by the US Social Security Administration (SSA). It started life in 1936 as a way to track earnings for retirement benefits. Today the US uses it as a de facto national ID number. Your taxes sit on top of it. Your credit file is keyed to it. Your employer reports wages against it. Most federal benefits you might later qualify for are tied to it.

Two things to know before you apply. First, your SSN is for life. You get one number and you keep it forever. You do not get a new one because you moved, switched visas, or changed your name. Second, the card itself is just a piece of paper. The number is what counts, and most of the time you will type it into a form rather than show the card.

The SSN comes from SSA, not USCIS and not the 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.

The short version: 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), or who have gotten a separate Employment Authorization Document (EAD, Form I-766) from USCIS.

Some statuses only open the door after a prerequisite is in place. F-1 students usually need an on-campus job offer plus a DSO endorsement before SSA will process the application. J-1 exchange visitors usually need a Responsible Officer (RO) sponsor letter. H-4, J-2, TPS, and asylum-pending applicants need the physical EAD card in hand first, 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 using an ITIN, and SSA will issue an official denial letter (Form SSA-L676) that most DMVs accept in place of an SSN for a state ID.

The exact path depends on your visa, your work basis, and sometimes your state. SettleKit works out which bucket you land in and what step comes next.

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

Employment

Your employer puts your SSN on your W-2 and your Form I-9 to prove you can work legally. Most employers cannot put you on payroll without it. Some will let you start work while the application is pending if you can show the SSA receipt, but that is a policy call, and not every HR system will accept it.

Banking

Most large US banks ask for an SSN to open interest-bearing accounts and to satisfy customer-identification rules under the Bank Secrecy Act. A handful of banks will open an account on a passport plus ITIN, or even passport alone, but the menu shrinks fast and the waiting times vary. SettleKit's bank-account guide filters providers to the ones that actually accept your status.

Credit

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

Taxes

The IRS expects an SSN on W-2s and 1040s. Without one you file with an ITIN. That is legal and common, but it is slower, some tax credits are off-limits, and some employer systems struggle with ITIN-only filers.

SSA accepts only original, unexpired documents. No photocopies. No notarized duplicates. No photos on your phone. 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 (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 DSO. J-1 exchange visitors whose DS-2019 lists the category Student, Student Intern, or International Visitor need an original, wet-signed RO sponsor letter on top of the DS-2019. H-4, J-2, and asylum-pending applicants need the physical EAD card. An I-797 approval notice by itself will be turned away at the counter.

The exact combination depends on your visa and work basis. Watch the signatures too. SSA routinely rejects DocuSign or printed digital signatures on DS-2019s and sponsor letters. When in doubt, wet ink.

The application is Form SS-5. Two ways to fill it out:

1. Start online. Most applicants can begin on SSA's online application portal. Same questions as the paper form. You get an Online Control Number at the end. Save it. At the SSA office that number replaces the paper form entirely.
2. Do it on paper. If online will not work for your case (no US mailing address yet, validation errors the portal will not let you past, or you cannot complete the form online for any other reason), print Form SS-5, fill it out, and sign it in wet ink.

A few things that trip people up. Your name on SS-5 has to match your passport exactly, middle names and all. The residential mailing address is load-bearing. That is where the card goes 2 to 4 weeks later. Double-check the apartment or unit number. Missing unit numbers are the number one reason cards come back undelivered. Commercial mailbox addresses (UPS Store, mailbox services) get flagged by SSA and the card will not be mailed there. Use a real residential address, an employer address, or 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 SAVE (Systematic Alien Verification for Entitlements), which pulls from DHS. SAVE is not instant. If you walk into an office the day after you arrive, verification either fails outright or kicks off a manual review that can push your card out by weeks.

The guidance most international student offices publish: wait at least 10 days after entering the US before applying, and (for F-1, M-1, J-1) make sure your SEVIS record has been active for at least 2 days. Once 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 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. OPT and M-1 EAD holders have to wait until the exact start date printed on the EAD. Applying a day early comes back as 'not authorized' and you get turned away.

If you started the application online, SSA gives you 45 days to finish the in-person visit. Miss that window and the Online Control Number expires. 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 (EAD card in hand, DSO endorsement, RO letter) is done.
2. Gather your originals. Passport, 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 or walk into your local SSA office. Some offices are appointment-only. Others take walk-ins. Plan on spending 1 to 2 hours on site.
5. Hand over your documents. The clerk verifies them through SAVE, confirms your identity, and keys your details into the system. Watch what they type. Once it is committed, the local office cannot fix the mistake. You have to route the correction through central SSA.
6. Leave with a receipt. You walk out with confirmation that the application is filed. The card is printed and mailed 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. Punch in your ZIP and it returns the closest offices with hours, phone numbers, and whether they take walk-ins or require an appointment.

Offices are not created equal. The big urban offices in New York, Los Angeles, and Houston tend to be appointment-only with wait lists that run into weeks. Suburban offices a half-hour drive out are often walk-in friendly and can process you the same morning. And if the office nearest to you is backed up, any SSA office in the country can take your application. Driving to the next town over is a legitimate option.

One edge case worth knowing. SSA processes your application locally, but the card is printed and mailed from a central facility. It goes to the residential address on your 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. USPS forwarding of an SSN card is unreliable. 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 DSO letter confirming enrollment. You can apply up to 30 days before your start date, which matters because orientation-week hiring is normal. F-1 OPT and STEM OPT applicants have to wait until the exact start date printed on the EAD card. Applying a day early gets refused. F-1 CPT applicants apply with a CPT-endorsed Form I-20 (the page 2 endorsement from your 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 an extra wet-signed 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 TPS applicants need the physical EAD card in hand. A USCIS approval notice (I-797) alone will not be accepted at the counter.

If an SSA clerk insists a document is wrong and you are sure it is not, stay polite but hold your ground. Clerks sometimes give incorrect guidance on international cases, especially rarer ones. Citing the specific SSA POMS reference that governs your case can resolve the dispute on the spot. POMS RM 10211.205(D) covers asylum applicants. POMS RM 10211.275 covers F-1 DSO letters. Having the citation ready on your phone is worth the two minutes it takes to bookmark.

Once SSA accepts your application and SAVE clears your status, printing and mailing the card usually takes 2 to 4 weeks. SSA's own published range for straightforward cases is tighter, at 7 to 14 business days, but SAVE verification for noncitizens routinely adds time, and field-office appointment backlogs have pushed real end-to-end timelines closer to 4 to 6 weeks since the EBE program pause in March 2025.

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

Timing matters for everything downstream. The usual sequence is SSN first, then driver's license or state ID, then bank account, then first credit card. Some of these you can start in parallel, since plenty of banks will open an account on passport plus visa while your SSN is pending. But the full financial stack opens up faster once the card is in hand.

The card arrives by regular USPS mail. No tracking, no signature required. It is a small paper card, not plastic, and the back has a line asking you to sign it in ink.

A few things to do the day it lands. Photograph both sides and store the image somewhere encrypted. A password manager works. You will need the number far more often than the physical card. Lock the card away in a safe, a locked drawer, or a safety deposit box, and do not carry it in your wallet. Memorize the number, because you will be typing it into forms for years and muscle memory beats fishing the card out every time. Finally, check name, date of birth, and number against your passport. If anything is off, contact SSA immediately. The earlier you flag an error, the less painful the correction.

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

Your SSN is one of the most valuable pieces of information a scammer can get hold of. The ground rules most newcomers only learn the hard way.

Once you know the number, leave the card at home. Do not carry it in your wallet. Do not hand the number out casually. The parties who have a legitimate reason to ask are employers, banks, the IRS, lenders running a credit pull, landlords running tenant screening, and state DMVs. If anyone else asks for it, ask what they need it for and whether a different ID will do. Often it will.

Be hostile to unsolicited phone calls. 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. Report the call to oig.ssa.gov.

Two accounts to open proactively. First, create a my Social Security account at ssa.gov/myaccount. Claiming the account under your own login blocks a scammer from creating one in your name. Second, put a credit freeze on all three bureaus: Equifax, Experian, and TransUnion. Free, fast, and it stops most new-account fraud at the door.

If you suspect your SSN has already been exposed, the FTC's identitytheft.gov walks you through a personalized recovery plan step by step.

The most common SSN headaches and what usually fixes them.

The card never showed up

Call SSA at 1-800-772-1213 after four weeks. Nine times out of ten the mailing address was incomplete (missing apartment number) or SSA's system flagged it as a commercial mailbox. SSA will reissue to a corrected address.

The name on the card does not match your passport

If you catch it within a few days, call the SSA office where you applied. If it has been longer, plan on filing a corrected Form SS-5 and showing updated documents.

The clerk committed wrong data

Local offices often cannot reverse a committed record. Escalate to central SSA by phone, or file a corrections SS-5.

Lost or stolen card

Request a replacement through ssa.gov/number-card. SSA allows three free replacements per year and ten in a lifetime. The number does not change. In most cases you do not actually need a new card. You need the number, and you already have that written down.

You are not eligible and need a denial letter

Most DMVs accept SSA Form SSA-L676 (an 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 and prints the denial letter on the spot.

Status-specific quirks (an EBE pause, a clerk refusing a valid document, a mismatch between your I-94 and your EAD) come up often enough that SettleKit builds the exact recovery path for your situation into the in-app steps.
