KB Kookmin Bank is Korea’s largest bank by branch and ATM network, which makes it a strong default choice if convenience and nationwide accessibility matter more to you than English support. As of 2026, KB has significantly streamlined the process for foreigners with app-based account opening — no branch visit required for many applicants. Here’s exactly how it works.
Foreign residents aged 19+ can open a KB WELCOME account entirely through the KB Star Banking app — no branch visit needed. You’ll need your ARC (or residency card equivalent), a Korean phone number, and an existing Korean bank account number for verification.
1. What You’ll Need Before You Start
📱 A phone registered under your own name with a Korean carrier — foreign carriers or prepaid SIMs won’t work for this process
🪪 Valid ID — Alien Registration Card (ARC), Permanent Residence Card, or Domestic Residence Report Certificate. Foreign passports and foreign driver’s licenses are not accepted for this app-based process
🏦 An existing Korean bank account number (any bank) — used purely for identity verification, doesn’t need to be a KB account
The name registered with KB Kookmin Bank must exactly match the name on your phone carrier registration and your ID — including spacing. If there’s a mismatch, you’ll need to correct it with either your carrier or at a KB branch before proceeding.
2. Step-by-Step: Opening an Account via KB Star Banking App
📱 Full App-Based Process
Step 1 | Download KB Star BankingAvailable on both iOS and Android app stores. This single app handles account opening, internet banking registration, and KB digital certificate issuance together.
Step 2 | Verify your ID
Photograph the front and back of your ARC, Permanent Residence Card, or Domestic Residence Report Certificate, plus complete account-based verification.
Step 3 | Set up your new account
Enter basic account details like your salary deposit date and document delivery preferences. You’ll automatically be enrolled in the foreigner-exclusive KB WELCOME account.
Step 4 | Register for internet banking
Choose an internet banking ID and set your transfer limits.
Step 5 | Set your simple password and pattern
This completes your KB digital certificate (KB국민인증서) issuance, which you’ll use for future authentication.
3. The KB WELCOME Account
New foreign customers opening an account through this app process are automatically enrolled in the KB WELCOME account — a standard checking/savings product type (보통예금/저축예금) with base interest rates around 0.1% annually. This functions like a regular Korean checking account and is suitable for salary deposits, bill payments, and everyday transactions.
4. KB Global Star Account — Worth Asking About
Foreign customers can also request the KB Global Star account, a foreigner-specific product that comes with:
💱 50% discount on currency exchange fees
💸 50% discount on international remittance fees
🆓 Waived internet banking transfer fees and ATM withdrawal fees, once you meet transaction requirements (salary deposits, KB card usage, or foreign currency transfers)
If you regularly send money home or receive international transfers, ask specifically about this account type when opening — it isn’t always the default.
5. What If You Don’t Have an ARC Yet?
If you need banking services before your ARC is issued, some banks allow a limited account opening with just your passport and proof of temporary residence — though functionality is restricted. For the full KB Star Banking app process described above, you specifically need an ARC, Permanent Residence Card, or Domestic Residence Report Certificate — a passport alone won’t work through this channel. If you’re in this situation, a branch visit may be necessary to discuss limited account options.

7. Branch Visit vs. App: Which Should You Choose?
| Situation | Recommended Path |
|---|---|
| You already have your ARC and a Korean phone number | KB Star Banking app — faster, no appointment needed |
| This is your very first Korean bank account ever | Consider a branch visit first — KB recommends first-timers consult with staff directly before using the app |
| You don’t have an ARC yet | Branch visit to discuss limited passport-based options |
| You want the KB Global Star account specifically | Either channel works, but confirm eligibility and ask specifically — it isn’t automatically assigned |
8. Common Mistakes to Avoid
❌ Trying to use a foreign passport for app-based verification — only ARC, Permanent Residence Card, or Domestic Residence Report Certificate work here
❌ Using a foreign-carrier SIM or prepaid USIM — the app requires a Korean carrier-registered phone number under your name
❌ Ignoring name mismatches — inconsistent spelling or spacing between your ID, phone registration, and bank records will block the process
❌ Assuming your ID is automatically valid — expired IDs, or IDs from someone who has already left Korea after their stay expired, are not accepted
9. Frequently Asked Questions
Q. Can I open a KB account entirely online without ever visiting a branch?
Yes, if you already have an ARC (or equivalent), a Korean phone number, and an existing bank account for verification. KB does recommend that first-time bank customers in Korea consult with branch staff before proceeding, but it’s not strictly required for the app process.
Q. Does the existing bank account I use for verification need to be a KB account?
No — any Korean bank account under your name works for the identity verification step.
Q. Is the KB WELCOME account the same as a regular savings account?
Functionally yes — it operates as a standard checking/savings account, just under a name specifically designated for foreign customers opening their first KB account.
Q. How do I get the KB Global Star account instead of the standard WELCOME account?
Ask specifically about it when opening your account, either through the app’s product options or by visiting a branch, since it isn’t automatically assigned by default.
Final Thoughts
KB Kookmin Bank’s app-based process has made account opening for foreigners significantly more convenient than it used to be — assuming you already have your ARC in hand. If you’re brand new to Korea and still waiting on your ARC, a branch visit to discuss limited options makes more sense. Either way, once you’re set up, KB’s nationwide branch and ATM network makes everyday banking noticeably more convenient than banks with smaller footprints.
