Choose the right register
The Internet Registry Office, iROS, provides access to the Korean courts’ registers. For companies, choose “법인”, legal persons. The competent registry generally depends on the head office, but ordinary register certificates may also be requested at another registry. [1] [4] [5]
DART is a separate source for company disclosures held by the Financial Supervisory Service. It contains documents of companies registered as filers in that system. [1] [7] [8]
Choose “법인” for company search, paid inspection and certificates.
Company profiles, reports, financial documents and disclosed holdings.
Search companies, report types and dates through an English interface.

Search step by step
Find the entity in the court register
Open the corporation search
Open iROS and select “법인”. Enter the legal company name under “상호” and search. The official illustrated instructions use this route to identify the corporate registration number. [5]
Select the matching company name
Choose the target entity from the name list and continue with “다음”, Next. Record the 13-digit “법인등록번호”. Compare it with your existing company documents or the DART company profile. [5] [7]
Choose inspection or a certificate
For reading the register, choose “열람” and pay KRW 700. For an official certificate, choose issuance, “발급”, at KRW 1,000 online. Also select the required document scope. [2] [3] [4]
Order the correct register certificate
Select current or deleted matters
“현재 유효사항” means currently effective matters. “말소사항 포함” includes deleted matters. “폐쇄사항” concerns closed records. “전부” means full information; “일부” means selected parts. [3]
Enter applicant and payment details
Complete the fields for the applicant, record and document scope. The procedure allows the cards, bank accounts or electronic-payment methods supported by the portal. Ordinary inspection and printable certificates differ from electronic-document certificates, which expressly require membership. [4]
Check the issued document and its authenticity
Keep the issued certificate. Paper certificates carry a 12-digit issuance-verification number and a two-dimensional code for authenticity checks. Do not confuse this verification number with the company’s 13-digit registration number. [3] [5]
Find annual reports, accounts and shareholdings
Match the DART company profile
Find the company in DART’s company directory. Its profile includes names, the representative executive and the corporate and business registration numbers. DART also includes filing companies outside the exchange market categories. [7]
Filter by report type and dates
Use the company name and a date range in the integrated search. Select “Annual Report” for annual company reports, “External Audit Matters” for audit documents, or “Equity Disclosure” for significant holdings. [6] [9]
Consult the original for precise findings
English disclosures are voluntary. The Financial Supervisory Service warns that they can differ from the Korean originals. Check the original filing for material details and take corrected versions into account. [6] [9]

What the register contains
The Commercial Registration Act covers several company forms and foreign companies. Certificate contents can include the name, head office, capital, purposes and registered officers. The record identifies the officer’s particular role. [1] [3]
A full certificate can omit branch and registered-manager sections unless those sections are requested. Select them expressly when needed. Older closed paper records have separate request and reservation procedures. [3]
Third-party access, membership and overseas use
Article 15 of the Commercial Registration Act allows any person to request inspection and certificates for a fee. Access to annexed file documents is limited to the part in which the applicant has an interest. Entitlement to a register certificate therefore does not confer access to the complete application file. [1]
The internet procedure does not require prior membership for ordinary inspection or a printable certificate. It does require registration for an electronic certificate issued as a document. Applicant and payment details remain necessary without membership. Use the payment methods offered by the portal; the rule expressly limits these to designated providers. [4]
DART disclosures are available over the internet without having to represent the company. The English interface helps international users but does not change the court register’s content or the scope of English disclosures. [8] [9]
Financial reports and DART coverage
DART separates annual, semi-annual and quarterly reports from external-audit documents. Its company directory contains companies registered in the filing system, including certain unlisted filers. [6] [7]
The Financial Supervisory Service does not certify the accuracy of every disclosure. It also warns that voluntary English disclosures have no independent legal effect and may differ from the Korean text. [9]
Shareholdings and beneficial ownership
DART includes reports of significant stock holdings and holdings of executives and major shareholders. These are securities disclosures for the companies covered. They are distinct from registered officers and from a full identification of the natural persons exercising ultimate control. [6] [9]
For a private company’s ownership chain, a registered officer’s name and the absence of a DART report are insufficient. Obtain appropriate ownership documents and check any intermediate companies in their own registers. [1] [3] [7]
Recognise pending changes
If a registration application is being processed, the service must flag that fact before inspection. Certificate issuance can be held until completion or the certificate can disclose the pending application. Check this notice when reviewing a company immediately before a transaction. [3] [4]
Avoid common mistakes
- A company’s 13-digit corporate registration number, its separate business registration number and a certificate’s 12-digit verification number are different identifiers. [3] [5] [7]
- Choose “말소사항 포함” for deleted entries. “현재 유효사항” excludes matters that are no longer effective. [3]
- A printable certificate and an electronic-document certificate follow different procedures. Membership is expressly required for the electronic-document route. [4]
Frequently asked questions
May I check a company that I do not represent?
Yes. Article 15 permits any person to request paid inspection and certificates. Inspection of annexed file documents is restricted to the part in which the requester has an interest. [1]
