}🟢find_korean_business(name, limit)
Find a Korean company by name (English or Korean) when you do not know its 10-digit business registration number — the number every other tool here needs. Returns ranked candidates with a confidence score and discriminating evidence (registration status, tax type, region), because a name can match several distinct companies: "Samsung Electronics" matches four. Sources: DART (disclosure filers, English names) and the Public Procurement Service registry (small businesses).
