사업자등록번호로 한국 사업자의 지금 상태를 확인해요.
- 상태 조회: 번호를 한 번에 최대 20개까지 넣으면 국세청에서 바로 계속·휴업·폐업 여부와 과세유형, 폐업일을 가져와요. 세금계산서를 끊기 전이나 계약 전에 거래처 목록이 아직 영업 중인지 한 번에 볼 수 있어요.
- 상호로 번호 찾기: 비즈위키에 있는 약 333만 곳 가운데 상호로 찾아요. 시도나 시군구로 좁힐 수 있어요.
- 법인 기본 정보: 법인이면 법인등록번호, 설립일, 상장 여부, 중소기업 여부, 종업원 수를 금융위원회 자료로 보여 줘요.
로그인 없이 조회만 해요. 대표자 이름, 전화번호, 이메일은 알려 주지 않고, 사람 이름으로는 찾지 않아요.
English Check Korean businesses by their business registration number (사업자등록번호).
- Status check: 1 to 20 numbers at once, live from the National Tax Service (active, suspended, closed or not registered), with VAT taxpayer type and closure date.
- Find a number by business name among about 3.3 million Korean businesses, optionally narrowed by city or district.
- Corporation profile: corporate registration number, founding date, stock market listing, SME status and employee count (Financial Services Commission data).
Read-only, no sign-in. Never returns representatives' names, phone numbers or email addresses, and does not search by a person's name.
