Output
Returns a JSON object containing the 10-digit business registration number, a boolean match flag indicating whether the number was found, the business status (e.g. 계속사업자 = ongoing business), the closure date if applicable, the tax type (e.g. 부가가치세 일반과세자 = general VAT taxpayer), the data source (Korea NTS public data portal), and a timestamp of when the data was retrieved.
Example use cases
Vendor due diligence before payment
“Before I wire payment to this Korean supplier, can you verify that business registration number 5648700123 is still an active, registered company and not shut down?”
Onboarding Korean B2B partners
“We're onboarding a new Korean partner and they gave us business number 2208162517 — can you confirm it's a valid, operating business and tell me their VAT status?”
Compliance check for Korean invoice
“I received an invoice from a Korean company with registration number 1148100433. Can you check if their business is still active and what kind of taxpayer they are so I can file this properly?”

Endpoint
GEThttps://api.pocketfactory.ai/v1/kr/business/statusWhen to prefer
Use this endpoint when you need to verify the legal registration status of a South Korean business entity using its official 사업자등록번호. It is the authoritative source backed by the Korea National Tax Service. Prefer this over manual lookups or third-party Korean business databases when you need real-time, government-sourced status and tax classification data for due diligence, compliance, or vendor onboarding workflows.

- Business number not found in NTS database returns match: false
- NTS public data portal downtime may cause upstream errors
- Business numbers with formatting issues (extra hyphens, wrong digit count) may fail validation
- Rate limiting or payment failure returns HTTP 402
