Behind the chaebol, South Korea runs on a vast base of SMEs and sole proprietors — on the order of 7 million businesses in all. Corporate entities are recorded in the Supreme Court's IROS registry, listed-company filings sit in DART, and tax identities come from the National Tax Service, making this high-tech export economy data-rich in Korean but hard to read from the outside.
Industries. Electronics and semiconductors, automotive, shipbuilding, and a deep manufacturing-supplier and services base lead.
Regions. Seoul and the surrounding Gyeonggi region dominate, with Busan, Incheon and the southeastern industrial belt.
The legal source of truth for South Korea is IROS (Supreme Court Registry). It records every legally trading company — identifier, status, address and often officers and filings — which is why it is the most complete and current starting point for prospecting. See the full register directory.
Stored databases such as Apollo and ZoomInfo are built from three sources — shared user contacts, bought lists and web scraping — each tilted toward companies with a visible, English-language web presence. A small parts supplier near Busan has an IROS record and a Korean-language site, but is rarely in a US-built, English-first warehouse.
| Segment | Share of firms | Online-footprint coverage |
|---|---|---|
| Large + chaebol-linked | small share | Good — usually covered |
| SMEs | variable | Variable — partial |
| Micro + sole proprietors | ~90%+ | Weak — under-represented |

South Korea identifies a company twice. The court-run IROS registry, operated by the Supreme Court, issues a corporate registration number and holds the certified extract of officers, capital and status; separately, the National Tax Service issues a ten-digit business registration number (format 000-00-00000) that appears on invoices and contracts. The two link to the same firm through different systems. Listed companies file disclosures in DART, run by the Financial Supervisory Service, while Statistics Korea (KOSTAT) frames the macro picture across electronics and semiconductors, automotive, shipbuilding and a deep supplier base.
For Apollo and ZoomInfo the obstacle is the Korean-language internet itself. IROS extracts are issued in Korean only, most SME and sole-proprietor activity lives inside the Naver and Kakao ecosystems rather than on indexable English sites, and US-built warehouses lean on English-first scraping and contributory contacts. So coverage is reasonable for chaebol-linked exporters and thin across the long tail — which is recovered by reading the registry and Korean web directly.
