South Korea has one of the most advanced digital banking ecosystems on the planet.
Apps like Kakao Bank and Toss have transformed everyday finance for tens of millions of Koreans.
For foreigners, though, the path is a little more conditional than the glossy apps suggest — most of the best digital banks require an Alien Registration Card and a Korean phone number before they fully open up to you.
This guide explains the best digital banks for foreigners in South Korea in 2026, how expats can actually open an account, what you need at each stage, and the practical workarounds for your first days before your paperwork is complete.
The two things that unlock Korean banking
Before comparing apps, understand the two keys that determine almost everything:
- The Alien Registration Card (ARC). Issued after you register your residence, the ARC is the document that turns “limited tourist banking” into full access. Without it, most banks will only let you open a restricted account — typically no internet banking and low balance limits — and the popular fintech apps won’t fully function.
- A Korean mobile number (010). Korea’s banking and payment apps rely heavily on mobile verification tied to a local 010 number. Many e-wallets and internet-only banks simply won’t onboard you without one.
Get both as early as you can. With an ARC and a 010 number, the entire digital ecosystem opens up. Without them, plan to lean on international money apps and foreigner-friendly traditional banks at first.
Internet-only banks for foreigners
South Korea has three licensed internet-only (digital) banks: Kakao Bank, K Bank, and Toss Bank. They are branchless, app-first, and hugely popular for fee-light banking, intuitive interfaces, and attractive products.
1. Kakao Bank — the leading neobank
Kakao Bank, tied to the ubiquitous KakaoTalk messaging app, is the most popular digital bank in Korea and one of the largest in Asia. It offers a clean, fee-friendly experience with savings products, easy transfers, and deep integration into daily Korean life. For foreigners with an ARC and a 010 number, it is a strong everyday account.
Best for: residents with an ARC who want the most widely used, convenient neobank.
Watch out for: onboarding generally requires an ARC and Korean phone number, and the app experience is more polished in Korean than in English.
2. Toss Bank — the fast-growing challenger
Toss Bank, part of the popular Toss financial super-app, is known for a slick interface, competitive savings, and modern features. Toss is also widely used by foreigners for its overall app, and some users report it being relatively accessible for opening accounts and even building a domestic credit profile over time.
Best for: residents who want a modern challenger bank with strong savings and a feature-rich app.
Watch out for: as with Kakao, expect ARC and 010-number requirements; English support varies.
3. K Bank — the original internet bank
K Bank was Korea’s first internet-only bank and remains a solid option for digital-first banking, with savings and everyday accounts. It is less commonly highlighted for foreigners than Kakao and Toss but is worth knowing.
Best for: residents wanting an alternative branchless option.
Watch out for: similar ARC and phone-number requirements; check current foreigner eligibility.
Foreigner-friendly traditional banks with strong apps
If you don’t yet have an ARC, or you want guaranteed English support, the major traditional banks are often the more practical starting point — and their mobile apps are genuinely good.
- KEB Hana Bank is widely regarded as one of the most foreigner-accommodating banks, with English service, a foreigner-oriented app experience, and easy international transfers.
- Shinhan Bank offers strong expat support and a well-regarded mobile app (Shinhan SOL) with English options.
- Woori Bank provides checking and savings with English-language service options.
- KB Kookmin Bank, the country’s largest by assets, offers reliable coverage and a capable app.
These banks can often open at least a limited account for newcomers, then upgrade you to full digital access once your ARC is in hand.
Money apps for your first days and cross-border needs
- Wise is usually the best option for fast, transparent, low-cost international transfers into and out of Korea, holding multiple currencies at the real exchange rate. It is invaluable for moving your savings over or sending money home.
- Revolut is convenient for travelers managing several currencies in one app, useful in your early days and for trips.
- T-money deserves a mention: this rechargeable transit card works for everyone regardless of visa status, handling public transport and many convenience-store purchases without any bank link — a handy bridge while your accounts are being set up.
Note that Korea’s local e-wallets — KakaoPay, NaverPay, and Toss payments — generally require both a Korean bank account and a 010 number, so they come online for you only after you have established local banking.
Digital bank vs. money app: the distinction
Kakao Bank, K Bank, Toss Bank, and the traditional banks are licensed Korean banks with deposit protection. Wise and Revolut are regulated money-services providers — excellent for cross-border value and convenience but protected differently from a Korean bank deposit, and they do not replace a local account for salary, domestic transfers, or daily Korean life.
How to choose the right setup
You have your ARC and a 010 number: open Kakao Bank or Toss Bank for the best everyday digital experience.
You just arrived without an ARC: start with a foreigner-friendly traditional bank like KEB Hana or Shinhan (often a limited account first), plus Wise for transfers and T-money for transit.
Your priority is moving money internationally: make Wise your transfer engine.
You want English-first support: lean toward KEB Hana or Shinhan, whose apps and staff cater well to foreigners.
The typical expat sequence is: arrive and use Wise plus a limited traditional account, get your ARC and 010 number, then open Kakao Bank or Toss Bank for full digital convenience.
Step-by-step: getting set up
- Register your residence and get your ARC. This is the master key to full banking access.
- Get a Korean 010 mobile number. Essential for verification across banking and payment apps.
- Open a foreigner-friendly bank first if needed. KEB Hana or Shinhan can often set you up (sometimes a limited account) before your ARC.
- Add an internet-only bank. Once you have your ARC and phone number, open Kakao Bank or Toss Bank.
- Set up money apps. Use Wise for transfers and T-money for transit from day one.
- Test before committing. Run small transactions and confirm limits, fees, and English support meet your needs.
Fees and pitfalls to watch
- No ARC, limited banking: without an ARC you typically get a restricted account with no internet banking and low limits.
- Phone-number dependency: many apps won’t onboard you without a Korean 010 number.
- Language: even foreigner-friendly apps are often richer in Korean than in English; check the English experience.
- E-wallet prerequisites: KakaoPay, NaverPay, and Toss payments need a local bank account and 010 number.
- App vs. bank protections: licensed banks offer deposit protection; money apps safeguard funds differently.
Frequently asked questions
Can foreigners open Kakao Bank or Toss Bank accounts? Generally yes, but you will usually need an Alien Registration Card (ARC) and a Korean mobile number. Without them, your options are limited to restricted accounts or international money apps.
Can I open any account without an ARC? Some traditional banks offer limited “non-resident” accounts with low limits and no internet banking. Full access typically requires an ARC.
Which bank is most foreigner-friendly? KEB Hana and Shinhan are frequently cited for English support and expat-oriented services, making them strong starting points.
How do I send money in and out of Korea cheaply? Wise is widely regarded as the most cost-transparent for international transfers, with Revolut useful for multi-currency travel.
Can I use KakaoPay or NaverPay as a foreigner? Usually only after you have a Korean bank account and a 010 number, since those are prerequisites for the e-wallets.
How long does it take to set up full banking in Korea? It depends mainly on how quickly you obtain your ARC and Korean phone number. Once both are in hand, opening an internet-only bank like Kakao Bank or Toss Bank typically takes only minutes in the app. Before that, plan on a limited traditional account plus international money apps for your first weeks.
Do I need to speak Korean to bank in Korea? Not necessarily, but it helps. Foreigner-friendly banks like KEB Hana and Shinhan offer English-language apps and support, while the internet-only banks are richer in Korean. Choose based on how comfortable you are navigating a partly Korean interface.
Building your financial life beyond the basic account
Once your everyday banking is sorted, a few extra steps make life in Korea far smoother.
Connect your e-wallets. With a local bank account and a 010 number in place, set up KakaoPay or NaverPay. These are woven into daily Korean life — splitting bills, paying small merchants, sending money to friends, and checking out online. Many domestic services (food delivery apps, taxi-hailing, train tickets, and major e-commerce platforms) assume you have one, so activating them unlocks conveniences that tourists simply can’t access.
Understand Korean credit. Korea has its own credit-scoring agencies (KCB and NICE). As a newcomer you start with a thin file, much like in other countries. Using a Korean account responsibly, paying any bills on time, and eventually holding a Korean credit or check card helps you build a domestic profile, which can matter for things like phone contracts and larger financial products down the line.
Mind the verification certificates. Korea historically relied on digital certificates and app-based authentication for online banking and payments. The system has modernised, but you may still encounter app-based identity verification tied to your phone number — another reason your 010 number is so central.
Keep a foreign-currency lifeline. Even after you’re fully set up locally, keep Wise or Revolut active. Korean banks’ own international transfer fees and exchange margins can be steep, so routing money home or topping up from abroad through a transfer specialist often saves meaningfully.
Common mistakes newcomers make
- Assuming the famous apps work on a tourist visa. Kakao Bank and Toss are spectacular — but generally only after you have an ARC and a Korean number. Don’t count on them for your first weeks.
- Skipping the 010 number. Without a Korean mobile number, much of the banking and payment ecosystem stays locked. Getting a local SIM early is one of the highest-impact moves you can make.
- Relying on a home-country card long-term. Foreign transaction fees and poor exchange rates add up fast. A local account plus Wise is almost always cheaper.
- Ignoring T-money on arrival. This cheap, no-ID transit card bridges the gap before your accounts are ready and is genuinely useful from the moment you land.
- Choosing a bank with weak English support when you need it. If your Korean is limited, prioritising KEB Hana or Shinhan over a less foreigner-oriented branch can save real frustration.
Final thoughts
South Korea’s digital banking is world-class, but for foreigners the sequence matters more than the brand. In your first days, lean on Wise for transfers, T-money for transit, and a foreigner-friendly bank like KEB Hana or Shinhan for a basic account. The moment you have your ARC and a Korean 010 number, open Kakao Bank or Toss Bank to unlock the full, fee-light digital experience that makes banking in Korea so convenient.
Prioritize your ARC and phone number above all, choose an English-friendly bank if support matters to you, and build the right combination. With those keys in hand, you’ll be banking like a local in no time.
