You’ve picked your entity, filed the registration, and gotten your business registration certificate back from the tax office. Then you sit down to open a corporate bank account in Korea – the step that’s supposed to be routine – and the branch asks for your representative’s Alien Registration Card, your registered corporate seal, a written explanation of where your capital came from, and a scheduled in-person appointment. None of that showed up in the incorporation checklist.
This is the second wall foreign founders hit in Korea, right after entity choice. It isn’t complicated once you know what’s coming, but it does take longer than most founders expect, and the account you open shapes what financial products – corporate cards, FX services, lending – you can actually use afterward. Here’s what the process really looks like, document by document, from a consultant’s seat across the table.

What You’ll Need: The Document Checklist for a Foreign-Owned Corporate Bank Account in Korea
Every bank in Korea asks for a broadly similar packet, though branch-level requests vary enough that it’s worth calling ahead before you go. At minimum, expect to bring:
- Business registration certificate (사업자등록증)
- Certificate of corporate registration (법인등기사항전부증명서), issued within the last three months
- The registered corporate seal (법인인감) and the matching seal certificate (법인인감증명서)
- The lease agreement for your registered office address
- The representative director’s Alien Registration Card (ARC) and passport
- A written explanation of the business’s purpose and the source of its capital – the item most first-time founders don’t expect
That last item exists because of Korea’s Act on Reporting and Use of Certain Financial Transaction Information, which requires banks to complete customer due diligence (CDD) before opening any account. Foreign-owned companies routinely get bumped into enhanced due diligence (EDD), which the Korea Financial Intelligence Unit (KoFIU) oversees. In practice, that means the bank wants to understand who ultimately owns and controls the company – the “ultimate beneficial owner,” or UBO – where the capital came from, and what the business will actually do day to day, not just what the articles of incorporation say on paper.
Business Consultant’s Note: I’ve watched account applications stall for two weeks not because a document was missing, but because the bank’s compliance team couldn’t connect the dots between a US parent company, an intermediate holding entity in a third country, and the Korean subsidiary sitting in front of them. If your ownership structure has more than one layer, prepare a simple one-page ownership chart before you walk in. It’s not a required form, but it answers the UBO question before the bank has to ask it three separate times – and in my experience, that alone can be the difference between a same-day approval and a two-week review.
The Account-Opening Process and Choosing the Right Branch
The representative director has to appear in person – there’s no fully remote path for a newly founded, foreign-owned company – and most banks want a scheduled appointment rather than a walk-in. What’s less obvious is that branch choice matters more than founders expect. Before you book, it’s worth confirming:
- Whether the branch holds a foreign exchange business license (외국환업무 인가) – not every branch of a given bank processes international wire transfers
- Whether the branch has a relationship manager who regularly handles foreign-invested companies
- Whether English-speaking staff (or staff in your language) are consistently on site, not just available by referral
- Whether the branch can issue a corporate card and internet-banking OTP token in the same visit, rather than sending you back a second time
Business Consultant’s Note: I’ve had two clients walk into two different branches of the same bank, carrying identical document sets, in the same month. One walked out with an activated account the same day. The other was told to come back in two weeks. The difference wasn’t the paperwork – it was the branch’s day-to-day familiarity with foreign-invested company accounts. Ask a few branches how many foreign-invested clients they currently serve before you commit to one.
Initial Limits, the Capital Transfer Step, and What Comes Next
Why Your New Account Starts With a Low Transfer Limit
Every new account opened in Korea – not just foreign-owned corporate ones – starts with restricted transfer and withdrawal limits, and banks generally won’t let a customer open multiple new accounts within a 20-business-day window. This is a nationwide measure against “daepo tongjang” (대포통장), the fraudulent bank books used in voice-phishing scams, and it applies uniformly. The limits typically lift once the account shows real transaction history – tax invoices issued, payroll runs, supplier payments – rather than on a fixed calendar date.
Moving Your Capital From the Promoter’s Account
Here’s a detail that trips up almost every first-time founder: the capital you paid in during incorporation sits in a promoter’s personal bank account, verified at the time by a balance certificate or capital-custody certificate. Opening the corporate account is a separate step, and the capital doesn’t move automatically – you need to transfer it in yourself. There’s no strict statutory deadline for this transfer, but in practice, leaving it in a personal account for too long turns it into a receivable on your books and can invite tax scrutiny, so most accountants recommend completing the transfer within roughly three months of incorporation.
Corporate Cards, FX, and Lending: Linking Your Account to Other Products
Once your account is open, Korean banks typically bundle a broader suite around it: corporate internet banking with built-in foreign exchange transfers, import-export financing, and B2B electronic payment – genuinely useful once you’re paying overseas suppliers or receiving capital calls from a parent company.
A corporate credit card is usually the next product founders want, but here’s the catch: several major card issuers won’t process a non-face-to-face application for a company with a foreign representative, a foreign parent, or co-representative directors – you’ll need a branch visit for the same KYC re-verification that opened your account in the first place.
Initial card limits also tend to start low, sometimes just a few hundred thousand won, and expand as three-plus months of revenue and transaction history accumulate; a handful of banks with SME-friendly lending policies move faster if you can show export contracts or policy-loan eligibility.
Business Consultant’s Note: One client didn’t set up FX-enabled corporate internet banking when they first opened their account – they assumed a basic account would cover everything. Two months later, when their US parent needed to wire working capital, they discovered their branch had to process it manually, and it took three separate visits over several weeks to get it done. Setting up the FX-enabled banking package on day one, even if you don’t need it immediately, avoids that entirely.
How Korea’s Corporate Banking Differs From What You’re Used To
Founders coming from the US, UK, or Singapore tend to assume corporate banking works the same way everywhere: a signature, an app, and you’re done. Korea runs on a genuinely different logic in a few specific ways.
The seal, not the signature, is still the company’s legal mark. Korea’s registered corporate seal (법인인감) functions as the company’s official signature for banking, contracts, and government filings. Even in 2026, the certificate proving that seal’s authenticity – the 법인인감증명서 – can’t be printed at home or in your office; it requires an in-person visit to a court registry counter or a corporate-use kiosk, because the registry has to visually compare the physical impression against its records. Most Western banking systems dropped the equivalent of a physical company seal decades ago in favor of an authorized signatory’s signature, wet or digital.
In-person verification for foreign representatives is structural, not optional. Fintech-forward business banks in the US, UK, and Singapore can often onboard a foreign-owned company entirely online within days. In Korea, the representative director’s in-person appearance is baked into the CDD/EDD process itself – it isn’t a workaround some banks skip and others don’t.
The tight initial limits aren’t a foreign-founder penalty – they’re universal. Founders sometimes assume the restricted transfer limits on their brand-new account signal something wrong with their specific application. They don’t. The daepo tongjang prevention rules apply to every new account opened in Korea, domestic or foreign-owned alike; it’s simply a banking-culture default that doesn’t exist in the same form in most other countries.
The digital certificate runs alongside the seal, not instead of it. A corporate “joint certificate” (공동인증서) – used for Hometax, Gov24, and the internet registry – is the closer analogue to a Western e-signature. But it exists as a second, parallel system, not a replacement for the physical seal. Both carry equal legal weight; you’ll end up needing both.
Business Consultant’s Note: The founders who adjust fastest are the ones who stop expecting a single, unified “login and sign” system and instead build a small internal routine around the dual system – who holds the physical seal, who manages the digital certificate renewal each year, and who’s authorized to request a new seal certificate when a landlord or bank asks for one. Skip that planning, and the seal becomes a bottleneck exactly when you need speed – during a financing round, a lease renewal, or a bank’s annual re-verification.
Checklist: From Application to Fully Activated Account
- Confirm your registered corporate seal and seal certificate are ready before you book an appointment
- Prepare a simple ownership chart if your structure has more than one layer above the Korean entity
- Call ahead to confirm the branch’s forex license, foreign-client experience, and same-visit card/OTP capability
- Bring the representative director’s ARC and passport – no substitutes accepted
- Transfer capital from the promoter’s personal account into the new corporate account, ideally within about three months
- Set up FX-enabled corporate internet banking at the same visit, even if you don’t need it immediately
- Plan your corporate card application as a separate, in-person step if your company has a foreign representative
Frequently Asked Questions
Can I open a corporate account before my ARC is issued?
Usually not for a full-service account. Without an ARC, you may only qualify for a restricted non-resident account until your representative’s residency status is finalized.
How long does account opening actually take?
With a complete document set and a branch experienced with foreign-invested companies, some clients activate an account the same day. Others wait roughly two weeks while compliance completes enhanced due diligence – the difference usually comes down to ownership-structure clarity and branch familiarity, not document completeness alone.
Can a foreign representative apply for a corporate card online?
Often not. Several major issuers require an in-person branch visit for companies with a foreign representative, foreign parent, or co-representative structure, to complete the same KYC re-verification used at account opening.
Do all banks handle foreign-invested company accounts the same way?
No. Requirements are broadly similar across banks, but branch-level experience with foreign-invested clients, forex licensing, and processing speed vary meaningfully – it’s worth comparing more than one branch before committing.
What happens to my capital between paying it in and opening the corporate account?
It sits in the promoter’s personal account, verified at incorporation by a balance or capital-custody certificate. You then transfer it into the new corporate account yourself – there’s no automatic transfer, and no strict legal deadline, though completing it within a few months is standard practice.
The Bottom Line
Opening a corporate bank account in Korea isn’t hard, but it runs on a different logic than banking in the US, UK, or Singapore – a physical seal that still matters, mandatory in-person verification for foreign representatives, and universal new-account limits that have nothing to do with your specific application. Once you’ve cleared that first account, the financial products that link to it – FX-enabled banking, corporate cards, trade financing – are what actually make day-to-day operations run smoothly.
