South Korea Blocks 27 Unregistered Crypto Exchanges, Including KuCoin

South Korean authorities have blocked domestic access to 27 unregistered cryptocurrency exchange websites, with KuCoin and MEXC among the platforms specifically identified in the enforcement action. The move targets exchanges operating without local registration, cutting off Korean internet users from the affected sites.

27 Websites Blocked Over Registration Failures

The action follows a pattern of escalating enforcement against foreign exchanges that serve Korean retail users without complying with local registration requirements. South Korea previously blocked 16 unregistered cryptocurrency exchanges in an earlier sweep by the Korean Financial Supervisory Authority, making this latest round a significant expansion of that effort.

KuCoin and MEXC are among the named platforms, though the full list of 27 blocked domains has not been confirmed in this report. The enforcement measure is a website-access block, meaning Korean users cannot reach the affected sites through standard network connections. It does not, based on available information, constitute a direct freeze of customer funds or wallets held on those platforms.

What an Unregistered Designation Means in Practice

Registration and local compliance

South Korea requires crypto exchanges serving Korean customers to register with the Financial Intelligence Unit and meet anti-money laundering standards. Exchanges that operate without that registration are considered unregistered, regardless of their licensing status in other jurisdictions. KuCoin and MEXC are both large global platforms with significant Korean user bases.

Access versus customer assets

A website block restricts access to the exchange’s front end but does not automatically affect balances, pending withdrawals, or assets held in user accounts. Korean users who already hold funds on affected platforms should monitor official communications from those exchanges directly for guidance on withdrawals and account access. South Korea has also been tightening related financial rules, with new crypto debt-recovery rules taking effect November 1, signaling broader regulatory tightening across the sector.

What to Watch Next

Official exchange updates

KuCoin and MEXC have not issued public statements on the block based on currently available information. Users should watch both exchanges’ official channels for announcements on service availability for Korean accounts and any steps being taken toward local registration.

Further regulator announcements

The full list of 27 blocked domains, the specific regulator behind the order, and any compliance deadlines for affected exchanges have not been independently confirmed. Key developments to track include an official published domain list, any registration applications filed by the named exchanges, and whether the FSC or FSS issues a formal statement. South Korean authorities have also opened criminal investigations into crypto-related activity in parallel with access enforcement, indicating enforcement is extending beyond administrative blocks.
