Everything Foreigners Need to Know About Registration, Appointments, Address Changes, and Reissuance in Korea (2026)
Many residents delay registration and later encounter problems opening bank accounts or obtaining mobile services.
For foreigners planning to stay in South Korea for more than a short visit, obtaining an Alien Registration Card (ARC) is one of the most important administrative steps after arrival. While finding housing, opening a bank account, and setting up a mobile phone plan are often top priorities, many of these tasks become significantly easier—or in some cases impossible—without an ARC.
The Alien Registration Card serves as the primary identification document for foreign residents in Korea. It functions similarly to a national identification card for Korean citizens and is used in banking, healthcare, telecommunications, taxation, housing contracts, online identity verification, and many other aspects of daily life.
This guide explains everything foreign residents need to know about the ARC in 2026, including eligibility, application procedures, required documents, online appointment systems, address changes, renewals, reissuance, and common mistakes to avoid.
What Is an ARC?
An Alien Registration Card (ARC) is an official identification card issued by the Korean immigration authorities to foreign nationals staying in Korea for an extended period.
The ARC contains information such as:
- Full legal name
- Nationality
- Date of birth
- Visa type
- Alien Registration Number
- Residential address
- Card validity period
The card is often requested when opening a bank account, signing a lease, purchasing a mobile phone plan, registering for health insurance, or completing government-related procedures.
For practical purposes, the ARC becomes the primary form of identification for most foreign residents in Korea.
Who Needs an ARC?
Generally, foreigners planning to stay in Korea for 90 days or longer are required to register and obtain an ARC.
Common visa categories requiring registration include:
- Student visas
- Employment visas
- Marriage visas
- Long-term residence visas
- Certain investment visas
- Various long-stay residence categories
Short-term tourists typically do not receive an ARC because their stay does not exceed the registration threshold.
For future retirees exploring long-term residence options, understanding ARC requirements early can help avoid administrative delays later.
Why the ARC Is So Important
Many newcomers underestimate how frequently the ARC is required.
Without an ARC, foreign residents may encounter difficulties with:
Banking
Many Korean banks require an ARC before allowing:
- Full account functionality
- Online banking registration
- International transfers
- Credit card applications
Mobile Phone Plans
Most postpaid mobile plans require ARC registration.
Healthcare
The ARC is often linked to:
- National Health Insurance enrollment
- Hospital registration
- Medical records
Housing
Landlords and real estate agents frequently request ARC information when preparing rental contracts.
Identity Verification
Many Korean websites require mobile-based identity verification connected to ARC registration.
When Should You Apply?
Foreign residents required to register generally must apply within the designated period after arrival.
Waiting until the last minute can create unnecessary complications.
Common problems include:
- Delayed bank account setup
- Mobile phone limitations
- Housing registration issues
- Healthcare enrollment delays
Applying as soon as practical after securing a Korean address is usually the safest approach.
Step 1: Prepare Required Documents
Documentation requirements vary according to visa category.
However, most applicants should expect to prepare:
Passport
Original passport with valid visa status.
Passport Photograph
Recent passport-style photograph meeting immigration specifications.
Application Form
Alien Registration application form.
Proof of Residence
Examples may include:
- Rental contract
- Housing confirmation
- Residence documentation
Supporting Visa Documents
Depending on visa type, immigration may request additional supporting materials.
Examples include:
- Employment contracts
- School enrollment certificates
- Family relationship documents
Requirements can vary significantly by visa category.
Step 2: Make an Online Immigration Appointment
One of the biggest mistakes newcomers make is assuming walk-in service will always be available.
Many immigration offices require advance reservations.
Making an appointment beforehand can dramatically reduce waiting times.
Benefits include:
- Faster processing
- Reduced waiting
- Guaranteed service slot
- Better planning flexibility
In busy cities such as Seoul, Busan, and Incheon, appointment availability can sometimes fill up weeks in advance.
For this reason, scheduling an appointment early is strongly recommended.

Step 3: Visit the Immigration Office
On the appointment date, bring all required documents.
Immigration officers typically:
- Review documentation
- Verify visa status
- Confirm address information
- Collect photographs if required
- Process registration
The exact procedure may vary by office.
Applicants should arrive early and ensure all documents are complete.
Missing paperwork is one of the most common reasons for delays.
How Long Does ARC Processing Take?
Processing times vary depending on:
- Location
- Application volume
- Visa category
- Seasonal demand
In many cases, applicants receive their ARC several weeks after completing registration.
During busy periods, processing may take longer.
Planning ahead helps avoid complications.
Understanding the Alien Registration Number
Once approved, the foreign resident receives an Alien Registration Number.
This number becomes extremely important because it is used for:
- Banking
- Tax administration
- Health insurance
- Mobile phone registration
- Government services
Many institutions request this number instead of a passport.
For practical purposes, it becomes the foreign resident’s primary administrative identifier in Korea.
How to Report an Address Change
Moving to a new residence is common among long-term residents.
However, many foreigners do not realize that address changes must generally be reported within the required timeframe.
Typical situations include:
- Moving apartments
- Relocating cities
- Changing housing arrangements
Failure to update address information can create administrative complications later.
Documents Often Needed for Address Changes
Examples may include:
- Updated lease agreement
- Housing contract
- Identification documents
- ARC
Reporting address changes promptly helps ensure immigration records remain accurate.
What Happens If the ARC Is Lost?
Losing an ARC can be stressful, but replacement procedures are available.
Common situations requiring reissuance include:
- Lost card
- Stolen card
- Damaged card
- Significant information changes
Examples of information changes:
- Name updates
- Nationality updates
- Visa category changes
Reissuance Process
Typical requirements include:
Replacement Application
Submission of a replacement request.
Identification
Passport and supporting documents.
Explanation of Loss or Damage
Depending on circumstances, additional documentation may be requested.
Applying for replacement promptly is advisable because the ARC is frequently required for everyday transactions.
ARC Renewal and Visa Extensions
Many foreigners confuse visa renewal and ARC renewal.
Although closely related, they are not always identical procedures.
Residents should monitor:
- Visa expiration date
- ARC expiration date
- Immigration requirements
Missing renewal deadlines can create serious complications.
Maintaining a calendar reminder several months in advance is highly recommended.
