Expanding into South Korea is exciting — but if you choose the wrong payment gateway, you can lose months in delays, rejections, and lost revenue.
Most companies underestimate how different the Korean payment ecosystem is compared to the US, UK, or EU. Providers like Stripe or copyright alone are rarely enough for Korean customers. Local cards, wallets, and authentication flows are critical.
This guide helps you understand how Korean gateways work — and how to choose the right one based on your situation.
Why Korea Is Different for Payments
South Korea has one of the website highest ecommerce adoption rates in the world — but also some of the strictest payment requirements.
Unlike other regions:
Many gateways require a Korean legal entity
Approval is manual and documentation-heavy
Foreign companies are often rejected without explanation
Some cards require Korean ID or phone verification
Refunds must follow Korean consumer protection law
Fraud rules and chargeback policies differ from Western gateways
Choosing the wrong provider means:
Approval failure
Higher fees
Delayed launches
Broken checkout for Korean users
The Most Common Korean Gateways (and When to Use Them)
TossPayments
Great for startups and modern platforms.
Fast UI, good API, but still entity-sensitive.
NHN KCP
Enterprise-grade, used by major Korean brands.
More paperwork, stronger compliance.
KG Inicis
Widely used, excellent merchant coverage.
Often required by marketplaces and larger platforms.
KakaoPay
Excellent UX for Korean users.
Limited for foreign businesses.
Each provider has different:
Required documents
Integration complexity
Settlement timelines
Foreign merchant acceptance rules
The Mistake Most Companies Make
They pick a gateway first…
…and only later discover they weren’t eligible.
Teams then scramble to:
Set up a Korean entity
Change business structure
Replace their checkout
Re-apply to another PG
Lose development time and money
This is completely avoidable with expert filtering first.
A Smart Approach That Saves Time
Before applying, you should know:
✅ Do you need a Korean business?
✅ Which gateway will approve you fastest?
✅ Which one supports your product type?
✅ Which platforms integrate best?
✅ What documents matter most?
✅ Which gateways accept foreign companies?
Without this, approvals become guesswork.
