Why Your Lease Contract Comes First in Korea

How Housing Unlocks ARC, Phone, Internet, and Daily Life in Korea

When relocating to South Korea, finding housing is not just about having a place to live.
A signed lease contract is the starting point that unlocks almost every essential service, including your Alien Registration Card (ARC), phone number, home internet, and banking.

Many expats underestimate how closely these systems are connected. This guide explains why your lease must come first and what processes depend on it.


1. A Lease Contract Is Your Official Proof of Address in Korea

In South Korea, a lease agreement functions as your official proof of residence.

Whether you rent an apartment, officetel, or villa, immigration offices, banks, and telecom providers all rely on your lease to confirm your local address.

Without a signed lease:

  • Your address is not recognized by immigration
  • Administrative registration becomes impossible
  • Most daily services remain inaccessible

In short, no lease means no official address.


2. You Cannot Apply for an ARC Without a Lease

Foreign residents staying long-term in Korea are required to obtain an Alien Registration Card (ARC).

To apply for an ARC, immigration offices typically require:

  • A valid passport
  • A signed lease contract showing your Korean address

Without a lease, your ARC application cannot proceed.
Until your ARC is issued, your legal and administrative status in Korea remains incomplete.


3. What You Cannot Do Without an ARC

Even if you already hold a long-term visa, many services are restricted until your ARC is issued.

Common limitations include:

  • Mobile phone plans
    Most telecom providers require an ARC to activate postpaid mobile services.
  • Home internet installation
    Internet providers require ARC-based identity verification before installation.
  • Opening a bank account
    Most Korean banks do not allow foreigners to open accounts without an ARC.
  • Signing contracts and daily services
    Car leasing, long-term subscriptions, and even parcel deliveries can be difficult without a verified local ID.

In practice, daily life in Korea starts after ARC issuance.


4. What If You Are Still Waiting for Your ARC?

If you have arrived in Korea but are still waiting for employment confirmation, furniture shipment, or final arrangements, consider the following options:

  • Short-term leases that allow address registration for ARC purposes
  • ARC-eligible housing arranged through a relocation agency
  • Confirming with landlords in advance whether address registration is permitted before full move-in

Landlords familiar with expat relocations may offer flexible arrangements that allow you to begin the ARC process without delay.


5. Summary: Your Lease Is the First Step to Everything Else

In South Korea, a lease contract is the foundation of a smooth relocation.
Once secured, it allows you to:

  • Apply for your Alien Registration Card (ARC)
  • Obtain a Korean phone number
  • Install home internet (KTSKTLG)
  • Open a bank account
  • Access essential services for daily life

If you are planning a move to Korea, start with housing that supports ARC registration.
