Verify South Korean counterparties in bulk. Paste company names or any Korean company ID. For each one you get:

  • one canonical entity with all its IDs;
  • the company's live tax registration status from the National Tax Service.

What it does

  1. Resolve. Names are matched in Korean or English. Legal forms (주식회사, ㈜, Co., Ltd.) are ignored, typos are tolerated and former names match (NHN → NAVER).

    IDs are recognised automatically:

    InputDetected as
    10 digitsBusiness registration no. (사업자등록번호)
    13 digitsCorporate registration no. (법인등록번호)
    8 digitsOpenDART corp_code
    6 charactersStock code
    20 charactersLEI

    Check digits are verified before any lookup. The index covers about 120,000 companies: OpenDART filers, all listed companies and GLEIF LEI records.

  2. Check status. Every business registration number found or typed in is checked live with the National Tax Service. The check returns:

    • status: active, suspended, closed or not_registered;
    • VAT taxpayer type;
    • closure date, if any.

    Numbers you type directly are checked even when the company is not in the index, so small private businesses work too.
