Korea's Limited Bank Accounts: How to Lift the Caps

The claim that a Korean limited account (한도제한계좌) “unlocks by itself after a few months of use” does not match how the system works. The core of the limited account is not transaction history. It is whether the bank has verified — with objective documents — why money moves through this account.

What a limited account actually limits

Caps in force since 2 May 2024 — an anti-fraud device, not a credit rating

Online transfer₩1M / day

ATM withdrawal₩1M / day

At the teller₩3M / day

Waiting quietly is the one strategy that never works here.

As of 2026, Article 2-6 of the Special Act on Telecommunications-based Financial Fraud obligates financial institutions to verify transaction purpose both at account opening and when lifting limits. If a customer submits no evidence, or insufficient evidence, the institution may cap transfers, remittances, and withdrawals; refusing identity verification, or a purpose judged connected to phishing fraud, can justify refusing the account or closing an existing one.

Which reframes the unlock application entirely. It is not an appeal that “I’ve been a customer for a while.” It is a demonstration: here is why this amount of money needs to move through this account. This guide — the deep-dive companion to our bank-account pillar — covers what actually counts as proof, situation by situation.

A purpose-verification device, not a credit rating

Ordinary bank KYC/CDD flows from the Financial Transaction Reports Act’s customer-due-diligence and anti-money-laundering framework — identity, beneficial ownership, transaction purpose — with enhanced due diligence (EDD) layered on statutorily where risk is higher.

The limited account adds a specific anti-fraud layer on top: purpose verification aimed at choking off voice-phishing and mule accounts. And since the August 2024 codification, calling it “just internal bank policy” is no longer accurate — verification is a legal duty, and institutions may demand supporting documents in writing, by email, or electronically.

The current standard caps, after the 2024 improvement:

Channel	Daily cap
Electronic banking	₩1,000,000
ATM	₩1,000,000
Teller (창구)	₩3,000,000

Banks and products can layer their own numbers on this base — KakaoBank currently allows ₩2,000,000/day app transfers on adult limited accounts (ATM transfer and withdrawal each ₩1,000,000). And the “stage 1 / stage 2 limited account” taxonomy circulating online is not a statutory tier system common to all banks; it generalizes some institutions’ internal product structures into an industry standard that does not exist.

Employees: prove the employment relationship, not the deposit count

For a salary-purpose account, the strongest evidence is not that pay has landed a few times — it is public-record proof that a real employment relationship exists.

The workhorse documents: the health-insurance eligibility certificate (건강보험 자격득실확인서), certificate of employment, employment contract, and payslips or earned-income records. KakaoBank names the health-insurance certificate as the representative salary-purpose proof and supports lookup via public MyData.

That MyData/scraping channel matters practically: with your consent, the bank queries public-institution records directly — no printed documents — and the FSC’s reform explicitly pushed this electronic verification to reduce paper submissions.

Foreign employees follow the same logic. An E-7 holder drawing normal Korean payroll is better served by presenting employment + salary + health-insurance enrollment as one coherent evidence stream than by waving an ARC alone. One timing note: right after joining a company, insurance data may not yet be queryable — bring the employment contract and certificate of employment to bridge the gap.

Sole proprietors: the registration certificate proves nothing about revenue

A business registration certificate shows you may do business — not that you are doing business.

A newly registered sole proprietor explains business substance with the office lease, supply contracts, purchase orders, licenses, and premises photos. Once trading, the evidence upgrades itself: e-tax-invoice issuance records, card sales, business-account inflows, the VAT tax-base certificate, and tax filings make “this account serves my business” nearly self-evident.

What matters is not the document count but whether the documents logically connect. A lease for a restaurant, a business registration for online retail, and a contract for something else again will earn you more scrutiny, not less. The foreign business owners covered in our business pillar run on the same principle — ₩30M of revenue arriving through the business account, matched by tax invoices and VAT filings, explains a transaction purpose far better than any stack of static registration papers. (The same records, incidentally, are what formalized freelancers gain over 3.3%-only earners.)

New corporations: with no revenue, prove the business is real

The new corporation’s structural problem is that even a perfectly legitimate company has no revenue history yet. KB Kookmin Bank’s guidance for new corporate and sole-proprietor customers explicitly contemplates premises inspections or equivalent evidence: the office lease, franchise agreements, the company homepage, interior and office-equipment receipts, startup-agency documents, signage photos, even road-view imagery.

Walking in with the corporate registry, business registration, and seal certificate and demanding “we’re a corporation, lift the cap” is often not enough. If deliveries have started, add contracts, tax invoices, and settlement inflows; if staff are hired, payroll transfers and social-insurance records demonstrate substance. What the bank is trying to establish is not that ₩100M of capital exists — it is what business this company conducts and what scale of funds will plausibly move through the account.

“No income” and “no purpose” are different problems

No salary does not mean no unlock. Utility or building-management bills and payment records tied to you or your address support a living-expenses purpose; national/local tax notices support a tax-payment purpose; telecom bills and autopay registrations support theirs — KakaoBank publishes exactly these as purpose-specific evidence examples.

Do not convert that into a formula (“three autopays for three months = unlock”). Banks weigh authenticity and actual transaction content — routing the real recurring costs of your life (rent, building fees, telecom) through the account reads naturally; a handful of artificial autopays reads as what it is. For a D-2 student or a non-working F-6 spouse, genuine living-expense flows are the realistic purpose story.

Foreigners often fail at identity matching before evidence

A recurring foreign-customer scenario: the non-face-to-face unlock is attempted, the applicant is a properly enrolled health-insurance member — and the lookup returns nothing.

The cause is frequently not a rejection but a matching failure. Does the ARC number registered at the bank match the public record? Was the customer file updated after a passport renewal? Is the romanized name on the ARC properly linked to the bank’s record? A single spacing difference does not automatically shatter your financial identity — but a history that started on passport identification and later gained an ARC or residence-report number, registered at different times, absolutely can produce lookup mismatches in non-face-to-face verification.

The fix is sequencing: stop re-submitting the app application and first clean up the bank’s customer identification at a branch — ARC, passport, stay information in hand, confirming which identifier your records actually live under. (The same hygiene protects your credit file.)

A non-face-to-face rejection is not the end of branch review

The app channel and the branch are not competing procedures — they verify differently. The app excels at standardized lookups (health insurance, business registration, tax data) and processes fast when your case fits the template. The branch exists for legitimate customers whose purpose cannot be told through standard data.

Two mirrored examples: a newly arrived foreign CEO with no VAT filings yet, but a signed office lease and a ₩500,000,000 supply contract, is a branch case — a human can read contracts and corporate documents that no automated pipeline ingests. A salaried employee with clean health-insurance data is an app case — public MyData beats carrying paper to a teller. Choosing the channel that best proves your purpose is not gaming the review; it is the review working as designed.

And no, branch staff cannot simply exercise discretion: the purpose-verification duty binds them too. There is no configuration in which charm substitutes for evidence.

Compare unlock criteria, not headline cap numbers

The major commercial banks (KB, Shinhan, Hana, Woori) run the standard ₩3M/₩1M/₩1M structure aligned to the regulator’s improvement plan. Internet banks vary operationally — KakaoBank’s ₩2M/day app transfers with in-app evidence submission; Toss Bank’s mobile evidence flows, with some products applying separate limits to foreigner accounts.

But bank-shopping the caps misses the point. If your business needs ₩50,000,000 of daily transfers, the difference between a ₩1M and a ₩2M limited cap is irrelevant — the only meaningful variable is which evidence converts your account to normal status. Secure the proof first; the bank choice is secondary. (And remember the used-car balance-payment trap: the day you discover the cap should never be the day a large payment is due.)

The unlock is a starting point, not a prize

Lifting the cap does not raise your credit score or create loan capacity. What it enables is concentration: salary or business revenue, card settlements, taxes, social insurance, and major expenses flowing through one account give the bank a long, legible view of your cash flow — which feeds everything downstream, from cards and FX for employees to business lending for companies. Long-term residents do well not to scatter their salary bank, card bank, and future loan bank too widely.

The inverse also holds: a student or short-term resident whose real monthly needs fit inside the caps has no obligation to chase the unlock at all.

What the bank is judging, throughout, is never the size of your wealth. It is whether the purpose and scale of money moving through this account can be explained with third-party-verifiable evidence — an employment relationship for salary, contracts flowing into tax records for business, genuine recurring outflows for living expenses. That is why the limited account is not a waiting problem. It is a proving problem.
