About BTSDB
BTSDB (btsdb.com) makes the parts of a Korean company that are already public actually checkable. Give it a 10-digit Korean business registration number — or just the company name — and it pulls the official record: whether the business is still trading, what kind of tax invoice it can issue, whether it is licensed to sell online, and roughly how many people it employs. No account, no app, free.
Where the open data stops — the owner and mortgages recorded only in the court register, the tax arrears shown only on a certificate — our document service picks up. That is the one paid part of this site.
- Registration status, tax type
- National Tax Service (국세청) — business registration status API
- Legal name, address, headcount, founding date
- Korea Workers' Compensation & Welfare Service (근로복지공단)
- E-commerce (mail-order) license
- Korea Fair Trade Commission (공정거래위원회)
- Pension subscribers, estimated pay
- National Pension Service (국민연금공단)
- Hospitals, specialties, out-of-pocket prices
- Health Insurance Review & Assessment Service (건강보험심사평가원)
- Travel information
- Korea Tourism Organization (한국관광공사) English service
Everything is fetched from Korea's public open-data platform (data.go.kr). See the weekly data reports for usage statistics.
Registration status is at most 24 hours old; company, pension and hospital records are at most 7 days old. Every card shows when it was last fetched, and busy pages refresh automatically each night.
These pages relay open government data. They are not a legal certificate, and figures such as estimated payroll are calculated from published formulas and clearly labeled as estimates. For a contract, a payment, or a filing, confirm through the official channel or your own advisor.
