What is in the data
152,367 Korean for-profit corporate headquarters with 10 or more insured employees.
| Field | Present |
|---|---|
| Employees (Employment Insurance) | 100% |
| Address in English | 100% |
| Established date | 100% |
| Monthly employment series | 91.9% |
| Corporate registration number | 70.5% |
| Phone | 69.3% |
| Listed market · DART code | 25.5% |
| Worksite addresses with headcount | 100% (25.5% have more than one) |
Registration numbers are validated against the National Tax Service. Where a value
could be read as more than it is, a companion field says what kind of value it is —
name_en_class, established_date_source, nps_quality. Which source each field
comes from is in the data guide.

What this does not do
No score, no grade, no ranking, no opinion about any company. No sanctions, penalties or litigation history. No personal data. Facts and their sources only.
Stability
The API is v0. Paths, parameters and field names may change without notice until
v1. Pin nothing you cannot change.
