If you’re planning to stay in Korea for more than 90 days, getting your Alien Registration Card (ARC) isn’t optional — it’s a legal requirement. The ARC is your primary ID as a foreigner in Korea, and without it, you’ll run into walls trying to open a bank account, sign a phone contract, or do almost anything that requires official identification. This guide walks you through the entire process for 2026, from first arrival to renewal and everything in between.
What Is the ARC and Who Needs One?
The Alien Registration Card (외국인등록증, oegugin deungnokjeung) is a government-issued ID card for foreign nationals residing in Korea. It contains your name, photo, nationality, date of birth, visa type, and a unique 13-digit alien registration number.
You are required to apply if you:
- Are staying in Korea for 91 days or more on a single-entry or long-stay visa (D, E, F, H series, etc.)
- Have a visa that permits work or extended residence
You do not need an ARC if you’re on a tourist visa (B-2) or a short-term stay of 90 days or less. However, even short-term stayers sometimes find the card useful — if your plans change and you extend your stay, you’ll need to register.
The legal deadline is within 90 days of your arrival date. Don’t wait until day 89. Immigration offices get busy, and appointment slots fill up fast in major cities.
Documents Required for Initial Registration
Bring originals and one photocopy of each document:
- Valid passport
- Completed alien registration application form (available at the immigration office or downloadable from HiKorea)
- One passport-sized photo (3.5cm x 4.5cm, white background, taken within 6 months)
- Proof of residence in Korea (lease agreement, utility bill, or letter from your employer/school confirming your address)
- Application fee: ₩30,000 (paid at the office)
- Visa-specific supporting documents (employment contract for E-series, enrollment certificate for D-2, etc.)

If your visa type requires additional documents — for example, E-7 technical workers often need an approved labor contract — check the Korea Immigration Service website or call 1345 (foreigner helpline, available in English) before your visit.
Where to Apply: Immigration Office or Online via HiKorea
In-Person at an Immigration Office
Find your nearest immigration office at the Korea Immigration Service website (www.immigration.go.kr). Major cities have dedicated offices:
- Seoul: Seoul Immigration Office (서울출입국·외국인청) in Mok-dong, plus branch offices in Gangnam and Nowon
- Busan: Busan Immigration Office
- Incheon: Incheon Immigration Office (close to the airport area)
- Daegu, Gwangju, Daejeon: Regional offices in each city
Make an appointment online before going. Walk-in queues exist but can mean waiting 2–4 hours. Online appointments are usually available within 1–2 weeks. Bring your documents, pay the fee, and your card will be mailed to your registered address within approximately 2–3 weeks.
Online via HiKorea
HiKorea (www.hikorea.go.kr) allows you to start the alien registration process online. You can submit your application, upload documents, and pay the fee electronically. However, most applicants still need to visit an immigration office at least once to complete biometric data collection (fingerprints and photo). Check the HiKorea website for the latest guidance on which steps can be fully completed remotely — the online pathway has expanded since 2023.
Receiving and Using Your ARC
Once your application is processed, your ARC is sent by registered mail to your Korean address. You’ll receive an SMS notification when it’s dispatched. If you’re not home during delivery, the card will be held at your local post office for pickup — bring your passport.
Your ARC number works as your ID number throughout Korea. You’ll use it to:
- Open a Korean bank account
- Sign a phone contract
- Register for health insurance (NHIS)
- File Korean income taxes
- Access government services
- Verify your identity online (via the government’s PASS app or similar)
Updating Your ARC: Address Changes and Visa Status Changes
Changing Your Address
If you move within Korea, you must report your new address within 14 days. This is a legal obligation, not optional. You can do this:
Source: Immigration Act (출입국관리법), 2026
- At your local district office (주민센터, jumin senteo) — fastest option
- Online via Government24 (www.gov.kr) if you have a digital certificate
- At an immigration office
Your ARC card itself doesn’t change when you update your address — the address is stored in the national database. However, you’ll get an updated record stamp if you request one.
Changing Your Visa Status
If you change your visa type (e.g., from D-2 student to E-7 worker), you must apply for a change of sojourn status at an immigration office. After approval, your ARC will be reissued with the new visa type printed on it. The fee for reissuing is ₩30,000.
Lost or Stolen ARC
Report a lost or stolen ARC immediately to the nearest immigration office. You’ll need to:
- File a loss report at the immigration office
- Submit a reissue application with passport, new photo, and ₩30,000 fee
- Wait approximately 2–3 weeks for the replacement card
While waiting for your replacement, carry your passport as your primary ID. If your card was stolen, filing a police report (at the nearest police station or via 112) is advisable, though not strictly required for reissue.
ARC Renewal and Expiry
Your ARC expiry date matches your visa’s expiry date. If you extend your visa, you’ll need to renew your ARC at the same time or immediately after. Apply for renewal at least 2–4 weeks before expiry — don’t let it lapse, as staying in Korea with an expired ARC is a visa violation and can result in fines.

Frequently Asked Questions
Can I open a bank account before I get my ARC?
Some banks (notably KEB Hana and IBK) allow foreigners to open a limited account with just a passport, especially if you have a work visa. However, most full-featured accounts require your ARC. Getting your ARC sorted early makes every other setup task significantly easier.
What happens if I miss the 90-day registration deadline?
You can still register after the deadline, but you’ll be subject to a fine. Late registration fines range from ₩100,000 to ₩1,000,000 depending on how late you are. Apply as soon as possible if you’ve missed the window — don’t keep delaying.
Does my ARC work as a substitute for a Korean resident ID (주민등록증)?
For most practical purposes, yes. The ARC is accepted as official ID at banks, hospitals, government offices, and for online verification. However, some services designed specifically for Korean nationals may require a resident ID number rather than an alien registration number.
Can I travel abroad with my ARC?
The ARC itself is not a travel document. You need your passport to enter and exit Korea. However, keep your ARC safe — you’ll need it when you return and re-enter Korea on your existing visa (if it’s a multiple-entry visa).
