The name on the invoice doesn't match the Korean register

You check a Korean company's registration number and the register returns a name you have never seen. The invoice says one thing, the official record says another. Before you conclude the number is fraudulent — the most common conclusion, and usually the wrong one — understand what a Korean company rename looks like from the outside.

Companies rename, numbers do not

A Korean company's registered name can change with a shareholder resolution and a filing. Its business registration number and its 13-digit corporate number never change with it. So when a company rebrands — and young Korean companies rebrand often, particularly after a pivot or new investment — every old invoice, contract and business card in circulation still carries the previous name against the same numbers.

A real example from this site's own records: a company registered in 2019 filed under one name until late 2020, then renamed. Six years later, its old name still appears in the register's first revision — same business number, same corporate number, one employee then, twenty now, and an address that moved from Incheon to Seoul along the way. A buyer holding a 2020 document would see a “mismatch” that is actually a company growing up.

How to confirm it is the same company

• Match on the number, not the name. If the 10-digit registration number on your paperwork resolves to an active registration, the entity is the entity — whatever it is called this year.
• Look at the filing history, not just the current record. The corporate register keeps every revision. If the name on your invoice appears in an earlier revision of the same number, the discrepancy is a rename, documented and dated.
• Ask the company directly. A legitimate company answers “when did you change your name and why” in one sentence. Evasion on that question is far more informative than the rename itself.

When a rename is a warning sign

Most renames are branding. A few are laundering a reputation. The difference is rarely in the rename itself — it is in what else moved at the same time. Treat the combination seriously when a recent rename arrives together with:

• a new address in a different city, with no operational reason offered;
• a change of representative in the same period;
• a request to pay a different bank account than earlier orders used — see payment to a personal account;
• an English trading name that has no connection to any registered name, past or present.
