South Korea company filings: the DART disclosure system
DART (Data Analysis, Retrieval and Transfer System), run by the Financial Supervisory Service, publishes the regulatory filings of listed companies and of unlisted companies that must have external audits: annual and quarterly reports, audit reports, major shareholder changes and other disclosures. It is the main free public source for Korean company accounts and ownership.
What it publishes
- Business (annual), half-year and quarterly reports of listed companies.
- External audit reports of companies above the audit threshold.
- Disclosures of major shareholdings and changes in ownership.
- Securities registration statements and other capital-market filings.
Key datasets
- DART search
Search filings by company name, period and report type.
APIs and downloads
- Open DART APIThe Financial Supervisory Service runs an Open DART API with free keys for filings and financial statements; see the DART site for the link.
When it publishes
Filings appear as companies submit them. Annual reports of December year-end companies are due by the end of March.
How to use it to check a claim
- Use the business report for revenue, profit, employees and executive pay.
- Check whether figures are consolidated or separate (parent-only).
- For ownership claims, check the latest major shareholding report, not an older annual report.
Common mistakes
- Small private companies below the audit threshold do not file on DART; the court registry holds their registration details.
- Corrected filings replace earlier ones; check for amendments.
Is DART free to use?
Yes. Searching and downloading filings on DART is free and needs no account.
