How to Use KakaoTalk When Renting an Apartment in Korea

If you're renting in Korea, KakaoTalk is not optional — it's how almost everything happens. Agents, landlords, building managers, and repair services all communicate through it. But there's a catch most foreign renters don't know about until they've already wasted time: Korean landlords and agents often don't respond to foreign phone numbers, and many don't use email at all.

This guide explains how to set up KakaoTalk properly so you're not invisible to the people you need to reach.

Why KakaoTalk — And Why Foreign Numbers Are a Problem

Korea has one of the highest KakaoTalk adoption rates in the world. For most Koreans, it has completely replaced SMS and email for everyday communication. Many landlords — especially older ones — check KakaoTalk throughout the day but haven't opened their email in weeks.

The problem for foreign renters: Korean agents and landlords are often unfamiliar with foreign phone numbers and may simply not respond to messages from numbers they don't recognize. An inquiry sent from a +1, +44, or +84 number can go completely unanswered — not out of hostility, but because it looks unfamiliar or potentially spam.

The solution is straightforward: get a Korean number before you start your housing search.

Setting Up KakaoTalk

Download KakaoTalk:

• iOS: https://apps.apple.com/app/kakaotalk/id362057947
• Android: https://play.google.com/store/apps/details?id=com.kakao.talk

Register with your phone number. If you don't yet have a Korean number, you can register with a foreign number as a temporary measure — but responses will be slower and some agents may ignore the message entirely.

Getting a Korean number: Korean SIM cards are available at Incheon Airport (arrival hall, all three terminals), GS25 and CU convenience stores, and Korean Telecom (KT) / SKT / LG U+ shops. A basic prepaid SIM costs ₩20,000–₩30,000 and can be purchased with your passport. Once you have a Korean number, re-register KakaoTalk with it.

💡 If you're still abroad and need to contact agents before arriving, asking Checkmate Korea to handle the initial outreach on your behalf is one way around the foreign number problem — agents respond to a familiar local number.

Once you have a Korean SIM (available at the airport or any convenience store), re-register with your Korean number. This makes communication with agents and landlords significantly smoother.

Finding and Contacting Agents

When you find a listing you're interested in — on Checkmate Korea, Zigbang, or Dabang — the contact option is usually KakaoTalk or phone.

What to send in your first message:

• Which listing you're interested in (address or listing title)
• Your move-in date
• How long you plan to stay
• Whether you have an ARC (foreign renters often get asked this early)

Keep it short. Agents handle many inquiries and respond faster to direct, specific messages than long introductions.

During the Viewing Process

• Request a video call viewing: If you can't visit in person, ask for a 영상통화 (video call) through KakaoTalk. Most agents are used to this request. During the call, ask them to show you specific things — the bathroom, the view from the window, inside the closet, the boiler.
• Save everything in writing: Any promise the agent or landlord makes — "we'll fix the boiler before you move in," "the maintenance fee includes water" — ask them to confirm it in the KakaoTalk chat. Written records in KakaoTalk are admissible as evidence in Korean legal proceedings if something goes wrong later.

Around Contract Day

• Confirming details: Before contract day, confirm the time, location, and who will be present via KakaoTalk. Ask for the exact address of the signing location if it's at the agent's office.
• Deposit transfer: Never transfer your deposit based solely on verbal or phone instructions. Ask the agent or landlord to send the recipient bank account details in writing via KakaoTalk. Cross-reference this with the property registry before sending.
• Move-in condition documentation: On move-in day, photograph any existing damage and send the photos to the landlord or agent via KakaoTalk immediately. The chat timestamp serves as your proof that both parties saw the unit's condition at move-in.

After You Move In

• Building manager (관리사무소): Most apartment buildings and officetels have a building management office. Save their KakaoTalk or phone number — you'll need it for maintenance requests, parcel deliveries, and parking issues.
• Maintenance requests: Send maintenance requests in writing via KakaoTalk rather than verbally. If you call, follow up with a text summary. This creates a paper trail if the landlord later disputes whether you reported an issue.
• Monthly rent payment: Most landlords expect rent paid by bank transfer on a specific date each month. Confirm the account number and payment date via KakaoTalk at the start of the tenancy and save the message thread.

For Move-Out

When giving notice that you won't be renewing, send it via KakaoTalk and keep the message. This is your proof of notice date — important if there's a dispute about whether you gave the required 2-month notice.
