Korea Residence Card (ARC): How to Register, Fees, Rules

Every long stay in Korea starts in the same place: a queue at the immigration office, a numbered ticket, and a fingerprint scanner.

The card you walk out with (a few weeks later) is the 외국인등록증, the foreigner registration card. Most English guides still call it the ARC, short for alien registration card. You will also see “Residence Card” on newer official pages. Whatever the name, it is the single document that turns a visitor into a resident on paper, and almost nothing in Korean daily life works without its 13-digit number.

This is Part 1 of our Living in Seoul 101 series, a set of practical guides for students, workers, digital nomads and working-holiday makers staying in Korea long term.

Who needs a residence card in Korea?

Anyone entering Korea who will stay more than 90 days must register as a foreigner, within 90 days of the date of entry. That covers the visas this series is written for: D-2 degree students, D-4 language students, E-series workers, F-1-D digital nomads and H-1 working-holiday makers.

Short-term visitors on K-ETA or visa-free entry do not register. If you are still working out how you enter Korea in the first place, start with our Korea entry guide and the K-ETA rules by nationality.

Ninety days sounds generous. It is not, in practice. Appointment slots at the busy Seoul offices can be booked out weeks ahead, and you need a fixed address before you apply. The realistic plan is to book the appointment in your first week, even if the date is a month away.

How do you apply for an ARC?

Book a slot on HiKorea, go to the immigration office that covers your home address, and submit the application in person with your documents and the fee. Immigration takes your fingerprints and photo, gives you a receipt, and tells you when the card will be ready.

📄 What to bring (confirm the visa-specific list on HiKorea before you go)

How long does the ARC take to arrive?

The application itself is processed on the day, but the card is printed and issued later. The Working Holiday Info Center, run by the Overseas Koreans Agency, tells participants that the card usually takes about three weeks. At busy times in Seoul it can take longer.

That gap matters, because the things you need the card for (a proper bank account, a postpaid phone plan) will wait until it arrives. Plan your first month around it: prepaid phone, limited services, cash and a foreign card.

What is the mobile residence card?

It is a digital version of your ARC stored in the government’s Mobile ID app, with the same legal effect as the plastic card. The Ministry of Justice began issuing it on 10 January 2025. It is available to registered foreigners aged 14 or older with a smartphone in their own name.

There are two ways to get it:

• IC card route. Cards issued since 1 January 2025 carry an IC chip. Tap the card against your phone in the Mobile ID app and the mobile card is issued. If you change phones, you can reissue it yourself the same way.
• QR route. If you have an older card without a chip, visit the immigration office with the physical card, verify your identity, and scan a QR code to issue it. Changing phones means another visit.

At launch the government said the mobile card could be used for identity checks at public offices, convenience stores, hospitals and major banks, with more private apps to follow. In practice, carry the plastic card as well for the first while: not every counter knows what to do with the mobile one yet.

What does the ARC unlock?

Your registration number is the key Korean systems ask for. Without it you keep hitting what we call the identity verification wall.

🔑 What changes once you have an ARC

What happens when you move house?

You must report your new address within 15 days of moving in. This is the 체류지 변경신고 (change of residence report). There is no fee.

You can file it at:

• the community centre (주민센터) of your new neighbourhood,
• the immigration office covering your new address, or
• online through HiKorea, which takes about three days to process. Online filing is limited to the applicant themselves.

Bring your passport or ARC and proof of the new address, such as a lease or accommodation confirmation. If you are unsure how Korean addresses are written, our guide to reading a Korean address helps.

The same 15-day rule applies to other changes on your registration: name, sex, date of birth, nationality, or a new passport (number, issue date or expiry date). A renewed passport is the one people forget.

What are the fines for late registration or reporting?

The legal maximums are steep, but people who are only a little late are usually told to pay a penalty set by immigration rather than being prosecuted. The law sets the ceilings; immigration decides the actual amount case by case, usually scaled to how late you were.

⚖️ Penalties under the Immigration Act (legal maximums)

If you realise you are late, go and report anyway. Coming forward yourself is always better than being caught at a visa extension, where the record will surface. Our guide to fines foreigners actually pay covers overstays.

What do you do with the card when you leave Korea?

For a trip abroad, keep it. Registered foreigners who leave and come back within one year (and within their permitted stay) generally do not need a separate re-entry permit. Show the card with your passport at the airport.

If you are leaving for good, the card goes back to immigration. You hand it in at departure immigration at the airport. Before you fly, also cancel your phone plan, settle your health insurance and close or update your bank account, so nothing keeps billing a card number that no longer exists.
