How this service works
사업자등록번호를 넣으면 국세청 기준 사업자 상태(계속·휴업·폐업), 과세유형, 폐업일을 돌려줍니다. 한 번에 최대 100건, 인증키 불필요. Korea business registration status check: given Korean business registration numbers (사업자등록번호), returns the National Tax Service (NTS) status (active / suspended / closed), VAT taxpayer type and closure date, up to 100 numbers per call. Source: NTS via data.go.kr. (sample input)
Output
Returns an array of business records, each containing: business registration number (b_no), registration status text (b_stt) and code (b_stt_cd), closure date (end_dt), whether under tax unit consolidation (utcc_yn), tax type and code, reverse billing tax type and code, invoice applicable date (invoice_apply_dt), and tax type change date (tax_type_change_dt). Also includes aggregate request_cnt and match_cnt fields.
Example use cases
Vendor compliance check before payment
“Before we process this invoice from a Korean supplier, can you verify their business registration is still active and they're eligible to issue tax invoices according to the 국세청?”
KYB screening for Korean business partner
“We're onboarding a new Korean business partner — can you pull their registration status from the National Tax Service to confirm they're not closed or deregistered and check their tax type?”
Invoice eligibility verification
“Can you check if this Korean company is allowed to issue VAT invoices right now by looking up their business status through the National Tax Service sample endpoint?”
Technical details
Endpoint
GEThttps://handsel-mandate-demo.vercel.app/biz/status/sample?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify the registration status or tax type of a Korean business entity via the National Tax Service (국세청), particularly for vendor onboarding, KYB compliance, invoice verification, or pre-payment due diligence. This is a sample endpoint, so prefer it for testing integration logic or validating response schema before using a production equivalent.
Side effects
- No matching business found — returns empty data array with match_cnt of 0
- Invalid or malformed business registration number — may return no results
- Sample endpoint may return static/mock data rather than live NTS data
- API unavailable or payment not processed — 402 or 5xx error
