Foreign companies seeking to trade through a Korean cryptocurrency exchange — whether to access Korean Won liquidity, recover assets from a previously dormant account, or run institutional crypto operations from abroad — quickly run into procedural barriers that are rarely well-documented in English. The single largest hurdle is opening and maintaining a Korean crypto exchange corporate account. Korean exchanges including Bithumb, Upbit, and Coinone all require a Korean resident representative, a tightly specified document package, and authentication that can take weeks to assemble. This post lays out what the process actually looks like in practice, drawing on a recent representation in which our firm acted as Korean Power of Attorney for a U.S. corporate client.

Why a Korean Resident Power of Attorney Is Required

Korean cryptocurrency exchanges do not allow foreign corporate clients to complete corporate Know-Your-Customer (KYC) verification remotely from abroad. The institutional sales teams at the major exchanges consistently require either that the CEO travel to Korea in person for verification, or that the company appoint a Korean resident as Power of Attorney (POA) to act on its behalf. Notably, exchange employees themselves cannot serve as the representative — only an independent legal representative qualifies.

This requirement reflects how customer due diligence operates under the Specified Financial Information Act (특정금융정보법, “SFIA”). The exchange must identify a real, accountable Korean-side counterparty, verify identity through in-person procedures, and maintain a verifiable Korean point of contact for ongoing regulatory follow-up. For most foreign clients, dispatching the CEO to Korea for what amounts to a multi-day administrative process is impractical, and engaging a Korean law firm as POA representative has become the standard approach.

The Document Package Korean Exchanges Require

A typical corporate KYC package for a Korean exchange consists of the following items, all issued within three months of the application date.

First, a Business Registration Certificate or equivalent business license issued by the company’s home jurisdiction. Second, a corporate registry document sufficient to verify the identity of the CEO and directors. Third, a shareholder list identifying the Ultimate Beneficial Owner (UBO). The Korean UBO requirement is unusually strict: if the direct shareholders are themselves corporate entities, the applicant must provide shareholder lists of those parent entities as well, continuing up the ownership chain until the ultimate natural-person owner is identified. Fourth, a set of exchange-specific application forms, typically including a Customer Identification Form, a Confirmation Form related to Virtual Asset Business activity, and a Consent Form for the Collection and Use of Personal Information. Fifth, a Power of Attorney authorizing the Korean representative to act on the company’s behalf, with the representative’s identification document attached.

Each document must then be authenticated for use in Korea. The standard path is notarization in the home jurisdiction, followed by an Apostille certification from the relevant authority — for U.S. documents, typically the Secretary of State of the issuing state. Documents not in English require notarized translations as well. Because each document is authenticated individually rather than as a combined package, applicants who bundle their documents into a single PDF before notarization often have to redo the entire chain.

A Practical Example: Recovering a Dormant 2021 Account

The corporate KYC framework applies not only to new accounts but also to legacy accounts that have been locked pending re-verification. In a recent matter, our firm represented a U.S. corporation that had opened a Bithumb account in 2021 and traded actively before the account was frozen pending updated KYC. During the dormant period, the exchange converted the held virtual assets into Korean Won, and the funds remained inaccessible until the company could complete the current corporate verification process.

Two features of the matter are worth highlighting because they recur in similar engagements. First, Korea’s corporate KYC process is currently designed for new clients seeking access to the planned corporate KRW market — a market that has not yet formally opened to corporates. Existing corporate clients are presently limited to crypto-only trading. Recovery of legacy assets therefore requires more than form submission; it requires direct compliance liaison with the exchange to confirm that the standard KYC flow is the correct path for unlocking the historical account rather than merely opening a parallel new one.

Second, we structure these engagements in two phases. Phase one covers the standard KYC application: POA designation, document review, form completion, and routine compliance communication with the exchange. Phase two covers the variable work — negotiation around legacy asset recovery, KRW conversion treatment, and retrieval of trading history or API access. Separating the two allows the client to control predictable application costs while reserving recovery work for hourly engagement only if the exchange’s response actually requires it.

Pitfalls and Realistic Timelines

The most common cause of delay is not exchange processing time but document preparation on the foreign company’s side. Notarization and Apostille certification in the United States typically takes one to three weeks, and any defect — an expired certificate, a missing parent-company shareholder list, or a single combined PDF where individual apostilles were required — restarts the clock. Once a complete package is submitted, the major exchanges generally process applications in two to three weeks, though this can stretch where UBO verification reaches multiple corporate layers.

Foreign applicants should also be aware that Korea’s regulatory environment for corporate crypto accounts is still developing. The corporate KRW market remains administratively closed pending further guidance, and exchange policies adjust periodically as the Financial Services Commission and Financial Intelligence Unit update their supervisory expectations. A KYC package assembled without recent guidance from Korean counsel is likely to require revision.
