SSN and IDNYC: getting the IDs New York actually runs on

New York doesn't care about your Medicare card or your myGov login. It runs on a nine-digit number and a couple of plastic cards, and you want all of them sorted in your first month.

The short version

• Your Social Security number (SSN) is the US version of a tax file number, plus a lot more. It's free, and you start online, then finish in person at a Social Security office [1][2].
• Wait about 10 days after you land before you go in, so the Social Security Administration can check your arrival record online [2].
• IDNYC is the city's free photo ID for residents aged 10 and over. It doubles as a library card and comes with free memberships at dozens of cultural institutions [3][4].
• A New York State non-driver ID costs from about US$10 in 2026 and is the card that works like a driver licence for ID, without the driving [5].
• 311 is the city's single number for non-emergency problems, from a heater that won't work to a noisy bar. Use it [7].

Why you need more than your passport

At home you juggle a TFN, a Medicare number, a licence and maybe a Keypass or a state photo card. The US has its own stack, and none of the Australian pieces carry over.

Here's what does what:

Aim for your SSN in week two and IDNYC or a state ID in month one, then put the passport back in the drawer.

Getting your Social Security number

The SSN is the number you'll be asked for more than any other. Your employer needs it to report your wages to the IRS. Banks, card issuers, landlords and health insurers ask for it. Our guide to building a US credit history from scratch explains why it matters for credit.

If you're on an E-3, H-1B, L-1 or another visa that lets you work, you're eligible. Your partner on an E-3D can also get one once they hold work authorisation. A non-working spouse usually can't, and may need an ITIN instead if they have a US tax reason.

What you'll need

The SSA wants original documents, or copies certified by the agency that issued them. Photocopies and notarised copies are not accepted [2].

• Your unexpired Australian passport
• Your US immigration document, usually your electronic I-94 arrival record (print it from the CBP website) or the admission stamp showing you can work [2]
• Proof of age, which can be your passport if you can't get your birth certificate within 10 business days [2]

Step by step

1. Wait 10 days after you arrive. The SSA says this lets it verify your Department of Homeland Security documents online, which speeds things up [2].
2. Start online at ssa.gov. If you're lawfully in the US, you can begin the application on the SSA website. In 2026 the SSA rolled out a streamlined online process, and some applicants may be asked to create or sign in to a my Social Security account [6].
3. Book or attend your office visit within 45 days. You must take your original documents to a Social Security office or Card Center within 45 days of starting online [2]. If you can't start online, you can fill in Form SSA-5 and call 1-800-772-1213 to book [2].
4. Wait for the post. Once your documents are verified, the card is mailed to you, usually in 5 to 10 business days [1]. If the DHS check needs a manual review, it can take longer.
5. Give the number to your employer and bank. Keep the card itself at home. You'll rarely need to show it, only the number.

Can you start work before it arrives? Usually yes: employers can put you on payroll while the number is pending. Ask HR.

Keep your TFN

Your SSN doesn't replace your Australian tax file number. Keep your TFN, myGov and ATO details current, because you may still lodge an Australian return in your first year. Our guide to your Australian tax residency after moving covers when you stop being a resident for tax.

IDNYC: the free card with the best perks

IDNYC is New York City's own government-issued photo ID. It's for residents aged 10 and over, and your immigration status doesn't affect whether you can get one [3]. It's free for anyone who applies through 31 December 2026; a replacement for a lost card costs US$10 [3].

What it does

• Works as your public library card, so you can borrow from the city's libraries [3][4]
• Gets you free one-year memberships at dozens of museums, zoos, gardens and performing arts venues. The city's own FAQ lists the count differently in two places, so check the current list on the IDNYC benefits page before you plan your weekends [3]
• Discounts on movies, gyms, sports and attractions [3]
• Accepted as ID by the NYPD and to enter city buildings [3]
• Can be used to open an account at some banks and credit unions listed on the IDNYC site [3]

What it doesn't do

IDNYC is not a driver licence and not a REAL ID. It won't get you on a domestic flight, and it doesn't give any immigration status or right to work [3]. Some bars and bottle shops may want a state ID or passport instead, so don't rely on it for proof of age everywhere.

How to apply

1. Gather your points. You need 3 points proving identity and 1 point proving NYC residency. The IDNYC Document Calculator shows what each document is worth [3].
2. Book an appointment through the online portal or by calling 311. New slots open every Friday for the following week [3].
3. Or walk in. Some centres take walk-ins on set days, such as Union Square on Thursdays and the Queens Public Library Jamaica branch on Fridays [4]. Check the current schedule before you go.
4. Bring originals. Staff look at your originals and hand them back. The program says it doesn't keep any original documents [3].
5. Watch your letterbox. The card is mailed to you [3]. Adults get a card valid for five years [3].

The residency point is the usual sticking point for new arrivals. Check the Document Calculator for what counts, and if you're in a sublet, get a bank statement sent to the flat early.

The New York State non-driver ID

If you don't plan to drive, the state non-driver ID is the most useful card after your SSN. It's issued by the NYS DMV, and it's what most people mean when they ask for "state ID".

Fees in 2026 for anyone under 62 are around US$10 for four years or US$14 for eight years, with a few dollars off if your birthday is within six months [5]. A REAL ID version costs the same; the Enhanced version adds US$30, but Enhanced is only for US citizens [5][8].

A first-time REAL ID needs an office visit. You'll bring proof of lawful status, identity and two proofs of New York State residency issued within the last year, and you get a temporary document on the day, with the card mailed in about two weeks [8]. The DMV's pre-screening tool tells you which documents to bring for your visa type.

For domestic flights you need a REAL ID-compliant card or your passport. A REAL ID lets you leave the passport at home on a weekend to Miami.

Planning to drive? Skip the non-driver ID and go for a full licence. Australia has no licence exchange with New York, so you'll be sitting the test. Our guide to driving in New York on your Australian licence walks through it.

311: the number every New Yorker uses

New York packs most of its non-emergency city services into one number. It runs 24 hours a day, every day of the year [7].

• Call 311 inside the city, or 212-NEW-YORK (212-639-9675) from outside the city or on a VoIP line [7]
• Text 311-692 [7]
• Use the NYC311 app or portal.311.nyc.gov to file and track a request [7]

It handles more than 500 types of service request and information on more than 2,000 city services and programs, with interpreters in over 175 languages [7]. Australians tend to use it for:

• No heat or hot water in your flat (heat season rules are strict here)
• Noise from a neighbour, a bar or construction at odd hours
• Booking an IDNYC appointment
• Missed rubbish collection, potholes and broken streetlights

Emergencies still go to 911, which is the US version of triple zero.

Keeping your Australian ID safe

Your Australian passport is now your proof of status as well as your identity, so treat it carefully. Once you have an IDNYC card or state ID, carry that and leave the passport at home.

If your passport is lost or stolen in New York, report it to police and to the Australian Passport Office straight away, then contact the Australian Consulate-General in New York, at 150 East 42nd Street in Midtown (+1 212 351 6500) [9]. Smartraveller's advice for the United States covers what to do and how to get emergency help [9]. Our guide to renewing your Australian passport overseas has the steps.

Scan your passport, I-94, visa and SSN card into secure storage, keep the SSN card itself at home, and update your address with the SSA, your bank and the DMV when you move, because cards are posted, not collected.
