Bizwiki Business Lookup

Bizwiki Business Lookup helps businesses check Korean vendors and clients: it looks up Korean businesses by their business registration number (사업자등록번호) and tells you whether they are still operating. - Status check: ask about 1 to 20 numbers at once and get each one's current status from the National Tax Service (active, suspended, closed, or not registered), VAT taxpayer type and closure date. Useful for checking whether a client or vendor list is still in business before issuing invoices or signing contracts. - Find a number by business name: search the Bizwiki database of about 3.3 million Korean businesses by registered name, optionally narrowed by city or district. - Corporation profile: for corporations, see the corporate registration number, founding date, stock market listing, SME status and employee count from Financial Services Commission data. Read-only and no sign-in. Bizwiki never returns representatives' names, phone numbers or email addresses, and does not search by a person's name. Businesses that asked to be removed from Bizwiki are not shown. Data sources: National Tax Service business status API (data.go.kr 15081808), Financial Services Commission corporate information (data.go.kr 15043184), and the Bizwiki database built from Korean public data.
