Quick answers
Why South Korea supplier verification matters
South Korea is a leading global supplier of semiconductors, displays, automotive components, shipbuilding, batteries, K-beauty, and increasingly EV-related materials. The Korean court registry (대법원 인터넷등기소) carries corporate filings; NTS issues the 10-digit Business Registration Number; FSS / DART hosts listed-company disclosures. Korean corporate data is comparatively transparent, but chaebol-related and SME supplier-fraud patterns concentrate in K-beauty drop-shippers and Alibaba-style trading intermediaries posing as manufacturers.
Active fraud patterns we see in South Korea
Trading company posing as a chaebol affiliate
Small trading entity uses 'Samsung / LG / SK / Hyundai' in its name or marketing to imply chaebol affiliation that does not exist.
KeyBS verifies the actual corporate-group structure and disclaimers; flags name-borrowing patterns.
K-beauty drop-shipper claiming manufacturer status
Online seller claims to be a manufacturer; in fact is a reseller or contract-manufacturing customer with no factory.
KFDA manufacturer registration and the Business Registration's actual activity codes are verified.
Closed (폐업) status hidden on invoices
Business Registration shows '폐업' (closed) but the supplier continues to invoice using an outdated certificate.
Live NTS Business Registration status check on every Korean verification.
KFDA / KC certification claimed but expired
Cosmetic / medical / electronics supplier presents an expired KC mark, KFDA, or food-safety certificate as 'current'.
KFDA / KC / NRF registry status is verified live, not from the supplier's PDF.
Personal bank account for corporate payment
Payment requested to an individual's account at KB Kookmin / Shinhan / Woori rather than a corporate account in the BR legal name.
Bank-beneficiary match (corporate account in BR legal name) is enforced from Essential upward.
Offshore HK / SG sub-entity without a documented link
Korean supplier directs payment to a Hong Kong or Singapore entity with no documented corporate relationship, often a capital-controls workaround.
Cross-border routing requires documented related-party rationale; otherwise blocked.

How do I verify a South Korean supplier before payment?
Cross-check the 10-digit Business Registration Number on NTS Hometax to confirm active status. Pull the 법인등기부등본 from iros.go.kr for directors, capital, and corporate acts. For cosmetic / food / pharma, verify KFDA / MFDS registration. Match the bank account to the BR legal name. For orders above USD 10k, KeyBS Trust verification combines NTS, Supreme Court Registry, MFDS, sanctions, and bank-beneficiary match.
What is the Business Registration Number?
A 10-digit number issued by the National Tax Service (NTS) that uniquely identifies every registered Korean business. It appears on every legitimate Korean invoice in the format XXX-XX-XXXXX.
How long does Korea supplier verification take with KeyBS Trust?
Standard: 1–3 business days. Enhanced (with MFDS / DART cross-check): 3–5 business days. Premium with Seoul / Busan / Incheon on-site visit: 5–8 business days.
What does '폐업' mean and why does it matter?
'폐업' means closed / dissolved on the NTS Business Registration. A supplier with 폐업 status cannot legally issue valid tax invoices — accepting one creates immediate accounting and tax exposure.
Can KeyBS verify listed-company affiliates via DART?
Yes. For suppliers claiming KOSPI / KOSDAQ-listed parent or affiliate status, KeyBS pulls DART disclosures to confirm the relationship and any related-party transaction restrictions.
Should I accept payment instructions to a Hong Kong or Singapore account?
Only with a documented related-entity link. Korean exporters typically settle via authorised foreign-exchange banks in Korea; unsolicited offshore routing is a fraud signal and may breach Korean FX-reporting rules for the buyer's local bank.
Does KeyBS verify K-beauty cosmetic exporters?
Yes. MFDS Cosmetic Manufacturer / Marketer registration is verified for every cosmetic supplier; the distinction between manufacturer and marketer is surfaced on the report so buyers understand who actually makes the product.
Can KeyBS check beneficial owners in Korea?
Yes — for non-listed entities via the Supreme Court Registry shareholder list, and for listed entities via DART. KoFIU disclosures supplement where available.
