Key Notes
- South Korea has approved domestic restrictions on 27 unregistered crypto websites, including KuCoin, MEXC and BingX, after reviews on October 6 and 7.
- The FIU plans withdrawal guidance through DAXA and operator cooperation because the blocks may disrupt access for existing customers.
- Website restrictions extend earlier app controls, while authorities will monitor replacement domains and can seek blocking before specific losses are reported.
South Korea has approved domestic website restrictions on 27 unregistered crypto service providers, including KuCoin, MEXC and BingX, extending an enforcement campaign that had already limited access to their mobile apps.
The Financial Intelligence Unit, part of the Financial Services Commission, announced the decision on October 13. The country’s communications standards review body approved access blocking or service termination after deliberations on October 6 and 7, following requests from the FIU.
The regulator acknowledged that the restrictions could make it harder for existing customers to withdraw assets. It said it would work with the Digital Asset Exchange Alliance, known as DAXA, and the relevant operators to provide detailed withdrawal instructions and support.
KuCoin, MEXC and BingX Among the Named Operators
The official attached list names 27 operators whose currently active websites were selected for the measures. Alongside KuCoin, MEXC and BingX, it includes Phemex, XT.com, Bitrue, CoinW, ZoomEX, Poloniex, BTCC and DigiFinex.
Other names include Pionex, Blofin, Apex Pro, WEEX, BitMart, KCEX, P2B, Nonkyc.io, SUPEREX and Xgram. The decision is aimed at services operating for Korean customers without the required local registration.
The notice distinguishes between access blocking for overseas-hosted services and termination where the server or operator is domestic. It does not provide a single nationwide activation time for every website, so the approval should not be read as confirmation that every Korean internet connection has already lost access.
The action concerns access within South Korea. It does not order the named businesses to cease operating everywhere else, and registration or authorization in another jurisdiction does not substitute for the Korean requirements described by the FIU.
Withdrawal Guidance Will Depend on Operator Cooperation
For customers with existing balances, the immediate issue is the ability to reach an account and complete a withdrawal. The FIU’s commitment to assistance recognizes that an access restriction can create practical difficulties for users even when its stated purpose is to prevent further harm.
The FIU did not specify an across-the-board withdrawal deadline or publish a platform-by-platform process. Its plan depends on DAXA providing guidance with cooperation from the affected operators, leaving the practical arrangements for individual customers to be clarified.
The FIU advised users to check whether their provider is registered and to withdraw their own virtual assets and deposits if they identify an unregistered service. It also warned against giving such businesses private keys, login credentials or copies of identity documents.
The agency said 28 virtual asset service providers were registered with it at the time of the notice. That figure describes the authorized-provider register and is separate from both the 27 websites covered by the blocking decision and the broader list of businesses referred for investigation.
How Overseas Platforms Fall Within Korean Rules
Under the framework described by the FIU, crypto businesses serving the Korean market must meet requirements including Information Security Management System certification and file the required registration. Overseas incorporation does not remove those obligations when a business targets Korean customers.
The authority considers factors such as a Korean-language website, marketing or customer-acquisition events directed at Koreans, and support for won payments. Its notice says those indicators are assessed together when determining whether an overseas provider is conducting business locally.
Unregistered operation can carry a maximum penalty of five years in prison or a 50 million won fine, the FIU said. These statutory penalties concern the business activity. The notice reports referrals to investigators rather than criminal convictions.
The regulator also warned that referral activity can, depending on the circumstances, amount to assistance with unregistered operations rather than ordinary advertising. It highlighted promises of guaranteed principal, unusually high returns and private information as warning signs in promotions.
Website Restrictions Add to Existing App Controls
The FIU said Google and Apple had already restricted new installations and updates of unregistered providers’ apps following its requests. The website decisions extend those measures to another route through which customers can reach the services.
Authorities have also instructed registered Korean providers to restrict virtual asset transfers involving identified unregistered businesses. The notice says 44 operators have been referred to investigative authorities over time, a broader enforcement total that should not be confused with the latest 27-site decision.
The FIU and the communications review body agreed that blocking need not wait for a specific victim complaint or a final criminal judgment. Review still forms part of the process. The agency plans to monitor replacement domains and request further decisions when providers try to continue through alternative addresses.
The action comes alongside other efforts to define South Korea’s regulated digital asset market. CoinScreamer has covered the proposed Digital Asset Basic Act and Bithumb’s compliance roadmap. Those initiatives remain distinct from the registration rules being enforced in this case.
