How to Open a Korean Brokerage Account in 2026 (No IRC)

Foreigners no longer need Korea's old IRC (Investor Registration Certificate) to open a stock trading account — that requirement was abolished on December 14, 2023. Individuals now use their passport number; corporate investors use a Legal Entity Identifier (LEI). Here's exactly how the process works today.

What Changed in December 2023?

For roughly 30 years, since 1992, any foreign investor — individual or institutional — had to pre-register with Korea's Financial Supervisory Service (FSS) and receive an Investor Registration Certificate before buying a single share of a KOSPI or KOSDAQ stock. The process was widely criticized internationally as slow, paperwork-heavy, and a genuine deterrent to foreign participation; the FSC itself noted that average monthly IRC issuance was only around 105 certificates in 2023, reflecting how few new foreign investors were entering the market under the old system. Effective December 14, 2023, the FSC abolished this pre-registration requirement entirely.

Do I Need an LEI?

It depends on your investor type:

• Individual investors: No LEI needed. You can open an account using just your passport number.
• Corporate/institutional investors: Yes, you need a Legal Entity Identifier — a 20-character alphanumeric global identifier, obtainable from any accredited Local Operating Unit (LOU) under the Global LEI System, typically within a few business days.
• Existing IRC holders: If you already have an IRC from before the change, continue using that number. You cannot substitute it with an LEI, and you don't need to re-register.

Three Ways to Open an Account

International broker (e.g., Interactive Brokers)	Non-residents wanting direct KOSPI/KOSDAQ access without visiting Korea	Standard international KYC; passport
Korean brokerage (Mirae Asset, Samsung Securities, KB Securities)	Korean residents (ARC holders) wanting local platform access and Korean-language research	Alien Registration Card, Korean bank account often required
US-listed ETF (EWY) via any US broker	Investors wanting simplicity and no Korean account at all	None beyond a standard US brokerage account

Step-by-Step: Opening an Account

• ☐ Decide whether you need direct share ownership or ETF exposure is sufficient
• ☐ If direct and non-resident: confirm your chosen international broker offers Korean market access
• ☐ If corporate: obtain your LEI in advance (this is the step most likely to cause delay)
• ☐ If Korean resident: gather your Alien Registration Card and confirm your broker's English-language support level
• ☐ Complete standard KYC/AML documentation (passport copy, proof of address, source-of-funds declaration for larger accounts)
• ☐ File a treaty benefit form (e.g., W-8BEN for US residents) at account opening to lock in reduced dividend withholding from day one

What Documents Will You Need?

At minimum, expect to provide: a valid passport, proof of residential address (utility bill or bank statement, typically within 3 months), and — for accounts above certain thresholds — a source-of-funds declaration. Corporate accounts additionally require entity formation documents, the LEI, and authorized signatory identification. This baseline hasn't changed post-2023; what changed is that the FSS-specific pre-approval step preceding all of this was removed.

FAQ

Can I still use my old IRC number if I already have one?

Yes. Existing IRC holders continue using their IRC number for account opening and are not required to switch to the LEI system.

How long does LEI registration take?

Typically a few business days through an accredited Local Operating Unit, though processing times vary by provider and completeness of submitted documentation.

Do individual investors need an LEI?

No — individual (non-corporate) foreign investors use their passport number instead of an LEI.
