ARC in Korea: Alien Registration Card Application Guide

What the ARC is

The Alien Registration Card, commonly called the ARC, is Korea's resident ID card for most long-term foreign residents. Korea has also used the English term "Residence Card" in some official contexts, but many foreigners, schools, employers, and service providers still say ARC.

Practically, the card is what turns you from a visitor into someone who can use normal resident services. Without it, you may be able to land, buy a prepaid SIM, use transit, and stay in temporary housing. With it, you can usually open a proper bank account, sign up for postpaid mobile service, complete real-name verification, and handle healthcare or tax systems more cleanly.

Who needs to apply

If you enter Korea and plan to stay for more than 90 days, you generally need to complete foreigner registration within 90 days of entry. This includes common long-stay categories such as study, language training, employment, investment, residence, spouse, working holiday, and many family-related statuses.

There are exemptions and edge cases. Diplomatic or official statuses, some short stays, and certain nationality/status combinations can be treated differently. Use this page as orientation, then verify your exact case on HiKorea or with the 1345 immigration contact center.

When to book the appointment

Do not wait until the end of your first 90 days. The legal timing is one thing; appointment availability is another. In busy immigration offices, the next available visit can be weeks away, especially around university intake periods and major hiring seasons.

1. After arrival, create or access your HiKorea account. You will use HiKorea for immigration appointments and many stay services.
2. Find the office responsible for your address. You normally visit the immigration office with jurisdiction over where you live, not whichever office is closest on a map.
3. Book the earliest realistic appointment. Leave time to prepare documents, print forms, get photos, and confirm school or employer paperwork.
4. Keep the appointment confirmation. Save it as a PDF or screenshot and bring it with you.

Documents to prepare

The base document set is similar for many applicants, but the exact attachments depend on your visa status. A D-2 student, E-2 teacher, E-7 employee, F-6 spouse, and D-8 founder will not all submit the same supporting evidence.

• Application form. Download or complete the relevant form from the immigration office or HiKorea guidance.
• Passport. Bring the physical passport, not just a copy.
• Color photo. Official guidance lists a 3.5 cm by 4.5 cm color photo for foreigner registration. Use the immigration photo standard, not a random social-media profile photo.
• Visa-status-specific documents. Examples include certificate of enrollment, employment contract, business registration documents, family documents, or employer/school confirmations.
• Proof of residence. This may be a lease, housing confirmation, dormitory confirmation, or other accepted proof of your Korean address.
• Fee. HiKorea guidance lists a 30,000 KRW fee for foreigner registration. Bring a payment method that works at the office; when in doubt, bring cash.

What happens at the immigration office

The visit is usually more administrative than dramatic. You check in, wait for your number, submit documents, answer basic questions if the officer has any, pay the fee, and receive instructions for card pickup or delivery.

If a document is missing or unacceptable, the officer may ask you to supplement it. That is another reason not to book at the last minute. You want enough time to fix a paperwork issue before your 90-day window becomes a problem.

After you apply

Processing time varies by office and season. After registration, you may receive a receipt or confirmation before the physical card is ready. Keep that document. Some service providers may accept it temporarily, but others will insist on the physical card.

Once the card is issued, check every detail immediately: name spelling, date of birth, nationality, status, stay period, and address. If something is wrong, contact immigration quickly.

What the ARC unlocks

• Banking. Most banks want your ARC, passport, Korean phone number, and address before opening a standard resident account.
• Postpaid phone plans. Prepaid is common at arrival, but postpaid and cheaper long-term mobile options usually become easier after registration.
• Housing. Long-term leases and address registration are easier when your resident identity is established.
• Healthcare. NHIS and medical administration are much easier once your resident information is in the system.
• Korean apps. Many services rely on real-name phone verification, which usually depends on ARC-linked mobile service.

Common mistakes

• Booking too late. The deadline is within 90 days, but available appointments may not care about your personal schedule.
• Using the wrong immigration office. Jurisdiction is based on address. Confirm before booking.
• Bringing incomplete residence proof. A vague Airbnb message or informal note may not be enough. Confirm what your office accepts.
• Assuming every visa uses the same document list. The base form is only the start; your status-specific attachments matter.
• Forgetting address-change duties later. After you receive the card, moving homes can create a separate reporting obligation. Check the rule before you move.
