주식회사, 유한회사 and the rest: reading a Korean company name

Korean company names carry their legal form in the name itself, usually as a prefix or suffix. Once you can read it, you know whether you are contracting with a corporation, a partnership, or a person.

The forms you will meet

주식회사 — the default

The overwhelming majority of Korean companies you will trade with are 주식회사. It is the standard stock corporation, roughly equivalent to a “Co., Ltd.”, and the form nearly every substantial business takes. The name may be written 주식회사 ABC or ABC 주식회사 — the position carries no legal difference, and in English it is usually rendered “ABC Co., Ltd.”

유한회사 — the quieter cousin

A private limited company. Liability is limited in the same way, but disclosure obligations have historically been lighter, which is why many Korean subsidiaries of foreign multinationals take this form. Perfectly ordinary to trade with; simply expect less public financial information.

합명회사 and 합자회사 — read carefully

These are partnerships, and in a 합명회사 every partner carries unlimited personal liability. You will rarely encounter them in commercial supply, and their rarity is itself worth a question: why is this business structured this way?

Why it matters commercially

The form determines who you can pursue if things go wrong. With a 주식회사 or 유한회사, your counterparty is the company and its assets — the individuals behind it are generally beyond reach. With a sole trader, the person is the business, which cuts both ways: no corporate shield, but also no corporate veil to hide behind.

If a company presents itself as a corporation, its tax number should say so too. The middle two digits distinguish corporations from individuals, so name and number should agree — and a disagreement is worth resolving before you sign.
