Verifying a Korean seller on Alibaba, TradeKorea or GobizKorea

Marketplace badges — Gold Supplier, verified member, years on the platform — measure a subscription, not a company. The only verification that counts is matching the storefront to a real Korean legal entity, and that takes one number and about two minutes.

What the platforms actually check

None of these platforms re-check a company after onboarding, and none of them stand behind a transaction the way an escrow service does. The badge answers “did someone register this storefront properly” — your question is “does the company exist, right now, and is this storefront actually theirs”.

Step one: get the registration number

Ask the seller for their ten-digit 사업자등록번호. A legitimate Korean exporter provides it without hesitation — it appears on every invoice they issue anyway. Reluctance to provide it is not a small red flag; it is the whole flag. With the number in hand, run a status check to confirm the business exists and is currently trading, and read our guide to what the digits themselves reveal about the entity type.

Step two: match the storefront to the entity

• Name. The registered Korean name and the storefront’s English name rarely match letter-for-letter — our guide to English company names explains what counts as the same company and what does not.
• Address. The listing’s address should agree with the registration district. A Seoul storefront whose registration sits in a different city deserves a question, not silence.
• Bank account. The beneficiary on the proforma invoice must be the company, at a Korean bank. A personal account is the classic exit ramp — here is why.
• Email domain. A company with a storefront and a catalogue but only a free webmail address is worth one more question. Not disqualifying alone — many small Korean firms genuinely use Naver mail — but it moves the burden of proof.
