Short trip to Korea? You don't need an ARC. Stay 91+ days? You do. Here's the exact rule, the process, and what happens if you skip it.
If you are in South Korea for 90 days or fewer, you do not need an Alien Registration Card (ARC). Full stop. The confusion arises because the ARC looks and functions like a national ID, which makes it tempting for short-stay visitors to assume they need one. They do not.

The Legal Threshold: 91 Days
The rule comes from Article 31 of the Immigration Act (출입국관리법). Any foreigner who stays in Korea for more than 90 days on a single entry, or who holds a long-term visa (D, E, F, H categories, among others), must register with the Korea Immigration Service (KIS) within 90 days of arrival. The ARC is the physical proof of that registration.
If you arrive on a K-ETA (Korea Electronic Travel Authorization), a tourist visa, or a visa-free entry under bilateral agreements, and you plan to leave within 90 days, you are entirely exempt.

Who Must Apply
You need an ARC if you:
- Hold a D-2 (student), E-7 (special occupation), F-6 (marriage migrant), or similar long-term visa
- Are on a working holiday visa (H-1) regardless of intended stay length, since these are inherently long-term
- Extend your stay beyond 90 days through a visa change at a KIS office
- Hold an F-4 (overseas Korean) or F-5 (permanent resident) status
You do not need one if you are on a standard tourist visit under 90 days, even if you exit and re-enter, provided each individual stay is within the permitted duration.
Where and How to Apply
Registration happens at any KIS office. In Seoul, the main offices are in Yangcheon-gu (서울출입국·외국인청, 서울특별시 양천구 목동동로 151) and Sejong-daero (near City Hall). Regional cities such as Busan, Daejeon, and Daegu each have their own KIS branches.
What to bring:
- Passport (original, valid)
- Visa or entry stamp confirming long-term status
- Two passport-sized photos (3.5 cm × 4.5 cm, white background)
- Completed Application for Alien Registration (Form 34, available at the office or on the KIS website: www.immigration.go.kr)
- Application fee: 30,000 KRW (cash or card accepted at most offices)
- Proof of address in Korea (lease contract, utility bill, or a letter from your employer or school)
You apply in person. There is no postal or online-only route. After submission, the card is mailed to your registered Korean address in roughly 14 to 21 business days.
What Happens If You Skip It
Failing to register within the 90-day window is a violation of the Immigration Act. Penalties include fines up to 2,000,000 KRW and, in serious cases, detention or deportation. Immigration officers can check registration status at any time, and some landlords and employers are legally required to verify ARC status before signing contracts.
Practical Uses Once You Have One
Once issued, the ARC functions as your primary ID for almost everything in Korea: opening a KEB Hana or KB Kookmin bank account, signing a phone contract with SKT, KT, or LG U+, registering for the national health insurance (NHIS), and proving identity at government offices. Some services still require your passport alongside the card for initial setup, but the ARC quickly becomes the document you reach for daily.
ARC vs. Passport at Banks
Most Korean banks now accept the ARC as primary ID for account opening. However, Kakao Bank and Toss require a Korean phone number first, get your SIM before attempting digital bank setup.
The short version: book your flight, enjoy your trip, keep your passport handy, and only think about the ARC if your stay is stretching past three months.
