South Korean regulators have ordered the blocking of 27 overseas cryptocurrency exchanges operating without proper local registration. The move was reported by CryptoBriefing, Coinfomania and Cointelegraph. Among the platforms named are KuCoin and MEXC, two exchanges with substantial international user bases.
The action falls under South Korea’s existing framework for virtual asset service providers. Foreign exchanges serving Korean customers are generally required to register with the country’s Financial Intelligence Unit. That registration requires compliance with anti-money laundering rules and the Travel Rule, which mandates sharing of sender and recipient information for crypto transfers above certain thresholds.
Exchanges that fail to register but continue offering services to Korean residents have faced periodic enforcement in recent years. Blocking domestic web access is one of the tools authorities use to limit unregistered platforms from reaching local users. It does not necessarily prevent determined users from accessing these services through other means, such as virtual private networks.
The inclusion of KuCoin and MEXC is notable given their scale. Both exchanges have large global trading volumes and have previously drawn scrutiny from regulators in multiple jurisdictions over registration and compliance practices. Neither exchange is reported to hold the local registration South Korean rules require for serving domestic customers.
South Korea has built one of the more structured regulatory regimes for digital assets in Asia. The country requires exchanges to partner with local banks for real-name verified accounts, enforces strict reporting obligations, and has periodically updated its list of sanctioned or blocked platforms. This latest action continues that pattern rather than representing a new policy direction.
The broader context is a global trend toward tighter oversight of cross-border crypto trading. Regulators in several countries have pushed unregistered exchanges to either obtain local licenses or exit those markets. South Korea’s approach of blocking website access, rather than solely pursuing legal penalties against operators, is one method regulators use when companies are based outside their jurisdiction and direct enforcement is difficult.
Sources disagree on this story
This article was published before the reports below were compared. The reporting above stands; what follows is where the published accounts do not agree.
Reports agree South Korea blocked 27 unregistered exchange websites, but accounts differ on when Google Play's app restrictions began.
What all sources agree on
- South Korea's FIU ordered blocking of 27 unregistered overseas crypto exchange websites, including KuCoin and MEXC.
- The decision followed Korea Communications Standards Commission (KCSC) reviews on October 6 and 7.
- 44 unregistered operators have been referred to investigative authorities.
- Credit card/payment restrictions on unregistered firms were introduced in May 2024.
- Unregistered platforms reportedly charge trading fees of 1.5% to 10%, compared with roughly 0.16% at major licensed Korean exchanges.
Where the reports disagree
1When Google Play's VASP registration requirement for app stores began
App stores came next. Google Play mandated VASP registration starting January 28, 2026. The requirement affected high-profile platforms like Binance and OKX.
Cointelegraph reported in April 2025 that South Korea had blocked downloads and updates for 14 unregistered crypto exchange apps on Apple's App Store, following restrictions on 17 apps through Google Play.
In March 2025, Google Play began restricting 17 unregistered exchange applications following requests from Korean regulators. Apple introduced similar controls in April, targeting platforms that had failed to complete local registration requirements.
What would settle it: FIU or FSC's own published timeline/press release detailing app-store restriction dates, or Google Play's/Apple's public policy announcement for Korean VASP registration requirements.
What to make of it
Treat the core facts — 27 blocked exchange websites, the October 6-7 KCSC reviews, and 44 referrals for investigation — as established across all sources. Do not rely on any single outlet's date for when Google Play's app-store restrictions began until the FIU or Google Play's own records are checked, since CryptoBriefing's January 2026 date conflicts with Cointelegraph's and crypto.news's March/April 2025 dates.
Market Impact
For Korean users of the affected platforms, the immediate effect is likely to be reduced direct access to trading on KuCoin, MEXC and the other 25 named exchanges. Users may need to rely on registered domestic platforms or alternative access methods, which carry their own risks and potential rule violations.
For the exchanges themselves, losing straightforward access to the Korean market could affect trading volumes tied to Korean users, though the overall scale of that impact depends on how significant Korean traffic was to each platform. The action also reinforces expectations that unregistered offshore exchanges operating in regulated markets face a growing risk of localized access restrictions, which could influence how global exchanges prioritize licensing efforts in Asia.
The blocking order underscores South Korea's continued insistence that overseas exchanges meet local registration standards before serving domestic users. It adds to a broader pattern of regulators worldwide tightening enforcement against unregistered crypto platforms.
Frequently Asked Questions
Which exchanges were named in South Korea's blocking action?
Reports from CryptoBriefing, Coinfomania and Cointelegraph identify KuCoin and MEXC among the 27 overseas exchanges blocked for lacking local registration.
Why did South Korea block these exchanges?
The exchanges reportedly lacked registration with South Korea's Financial Intelligence Unit, a requirement for virtual asset service providers serving domestic users.
Does blocking access fully prevent Korean users from using these exchanges?
Blocking domestic web access restricts direct access, but it does not guarantee that users cannot reach these platforms through alternative methods such as VPNs.
Is this the first time South Korea has restricted unregistered exchanges?
No. South Korea has periodically enforced registration requirements against foreign exchanges, and this action continues that established regulatory pattern.
