    South Korea: choosing and checking the right record

    Choose the correct source
    Use DART for corporate disclosures and filings in its scope. For a legal registration check, consult the relevant registration service rather than assuming every small Korean business must appear in DART.
    Confirm the entity
    Keep a DART company code separate from a corporate registration number and a business registration number. Compare the Korean legal name and the entity behind an English brand name.

    Check current access and document options on the official DART / Supreme Court Registry site. For search limitations and missing-result guidance, see the South Korea registry guide.

    Where do I find a South Korea company's registration number?

    Every registered South Korea entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its DART / Supreme Court Registry record.

    Is a South Korea registration number the same as a VAT number?

    No. The registration number is the identifier issued by the DART / Supreme Court Registry when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
