Identifiers

Send the business registration number as business_entity_id, with country_code set to KR.

Identifier	Format	Example
Business registration number	10 digits	`1234567890`

You can also search by legal name.

Statuses and legal forms

Every result carries the register's own status in registration_info.status and an AiPrise status in registration_info.normalised_status. The normalised status is one of Active, Suspended, Dormant, Dissolved / Struck Off, In Liquidation / Insolvency or Unknown.

Register status	Normalised status
continuing business operator	Active
Closed Business (Date of Closure: YYYYMMDD)	Dissolved / Struck Off
Business Closed (Date of Closure: YYYYMMDD)	Dissolved / Struck Off

entity_type holds the NTS taxpayer type, for example Head office of a for-profit corporation or Individual taxpayer, not a legal form.

Quirks and gotchas

Country-specific behaviour to know before you integrate.

Quirk	Details
Taxpayer type, not legal form	`entity_type` tells you if the business is a corporation or an individual taxpayer. About 4 in 10 results are individual taxpayers (sole proprietors).
Closure date in the status	Closed businesses carry the closure date inside the status text, for example `Closed Business (Date of Closure: 20250731)`.
Representative is a field	The representative's name comes back as a company field, not as a related person.
Many officer titles are UNKNOWN	Titles such as `Executive Director` and `Auditor` come back with the normalised role `UNKNOWN`. `CEO` and `President` normalise to `CONTROLLING_PERSON`.

Limits

Officers and shareholders are returned for some corporations only.
UBOs and register documents are not returned.
