Korea’s certificate system, translated the way U.S. receivers read it
Ask a Korean registry for a “birth certificate” and you will learn there is no such document: since Korea retired the old family register, proof of birth, parentage and marriage lives in separate purpose-built certificates — the basic certificate (기본증명서), the family relation certificate (가족관계증명서) and their siblings. EKO 4 National Translation Service works with them every day: complete, word-for-word certified Korean-to-English translation, every registrar seal accounted for, a signed accuracy affidavit on official letterhead and our wet stamp — all covered by a 100% acceptance guarantee.
The other trap is spelling. Korean surnames step into English many ways — the same 이 can be Lee, Yi or Rhee — and an immigration officer will line every document up against your passport. Our linguists lock one romanization across your entire file, read hanja wherever it appears beside hangul, and mirror the certificate’s layout so entries can be compared line by line. Serving all 50 states since 1991, with express 24-hour delivery when the deadline is close.

Why EKO 4 for this language
One case, the right certificate
Korea issues family relation, basic and marriage relation certificates as separate documents. Tell us what your receiver is asking for and we translate exactly that — or advise you, free, which one to request from the registry.
One name, one spelling
Lee, Yi or Rhee: we take the romanization from your passport, confirm it with you, and apply it across every certificate in your order — with hanja read correctly wherever the record uses it.
Certification USCIS recognizes
A signed certificate of accuracy on company letterhead with a wet stamp — the full 8 CFR 103.2(b)(3) package, standing behind our 100% acceptance guarantee.
Need it official? One order covers the whole chain
Certified translation, notarization and apostille — handled in-house, in a single online order, wherever in the country you are.
Certified translation
Word-for-word translation with a signed accuracy affidavit, official letterhead and wet stamp — accepted by USCIS, courts and authorities nationwide.
Notarization
A licensed notary notarizes your translation 100% online — no office visit, ready as fast as the next business day.
Apostille
We obtain the apostille from the correct competent authority — the issuing state’s Secretary of State, or the U.S. Department of State for federal documents — end to end.
Korean translation — questions & answers

EKO 4 National Translation Service delivers professional, human translation
in up to 72 languages — coast to coast
Every certified translation at EKO 4 is produced by a vetted human linguist — educated, widely experienced and genuinely at home in both of their languages. That is what allows us to stand behind a 100% accuracy guarantee across more than three decades of work.
From our first project in 1991 to the 50,000+ clients we serve today, the formula has never changed: careful translators, disciplined proofreading and honest service. It is why a first order so often becomes a working relationship that lasts for years.
EUROPEAN
ASIAN, AFRICAN, MIDDLE EASTERN
No translation leaves our hands on a single pass. Before any linguist joins EKO 4 they are recruited, vetted, interviewed and examined; once on a project, their work moves through editors and project managers who proofread it again before it ever reaches you. That layered process is the machinery behind our 100% accuracy guarantee.
Most of our 500+ translators and editors have spent years inside international, multi-cultural projects, so the finished document does not merely say the right words — it speaks to the audience, authority or market it was written for.
Professionalism, precision and fair pricing, backed by a 100% quality guarantee. Wherever in the country you are, EKO 4 speaks your language — explore all of them on our languages page.
