How Korean names work

Korean names put the family name first and the given name second. In 김민수 (Gim Minsu), 김 is the surname and 민수 is the given name. This is the reverse of the usual English order, which can be confusing at first. On English forms, using separate surname and given-name fields avoids mix-ups.

Most Korean names have three syllables: a one-syllable surname and a two-syllable given name, such as 이지은 (I Jieun) or 박준호 (Bak Junho). Some people have a one-syllable given name, and a few surnames have two syllables. Name lengths have become a bit more varied recently.

The most common Korean surnames are 김 (Kim), 이 (Lee) and 박 (Park), and a very large share of the population has one of these three. Meeting someone with the same surname is common. Other frequent surnames include 최 (Choi), 정 (Jeong), 강 (Kang) and 조 (Jo). For exact figures, see Statistics Korea census data.

본관 (bongwan) is the ancestral home region of a family clan. Two people with the surname 김 (Kim) may belong to different clans, such as the Gimhae Kim or the Gyeongju Kim. The surname plus the 본관 identifies a family line, and the 본관 is recorded in official family documents.

No. In Korea, both men and women keep their own surnames after marriage, so spouses having different surnames is completely normal. The Western custom of taking the husband's surname is not common in Korea. Some Koreans living abroad choose to change their name on foreign documents, but that is a personal choice.

In principle, Korean children take their father's surname. Under revised law, however, parents can agree when registering their marriage to give children the mother's surname. Exact conditions and procedures are set by law, so check official guidance. The system continues to be discussed as society changes.

This tradition is called 돌림자 (dollimja) or 항렬자 (hangnyeolja): members of the same generation in a family share one syllable in their given names. For example, brothers might be named 민수 (Minsu) and 민호 (Minho). It once showed each person's generation within the clan. Many families no longer follow it.

Yes. Some names use native Korean words, such as 하늘 (Haneul, 'sky'), 보람 (Boram, 'worth'), 슬기 (Seulgi, 'wisdom') and 나래 (Narae, 'wing'). Traditionally most names were built from Chinese characters with chosen meanings, but some parents prefer native words. These are often called 'Hangul names' and feel warm and direct.

In first meetings or formal settings, using the full name plus 씨 (ssi), as in 김민수 씨 (Gim Minsu ssi), is safe. As you get closer, the given name plus 씨, like 민수 씨, is common. For people senior to you, use their job title instead of their name.

Using only the surname with 씨, like 김 씨 (Gim ssi), can sound condescending, so be careful, especially with elders or people you've just met. Use the full name plus 씨 or a job title instead. Combining a surname with a title, like 김 선생님 (Gim seonsaengnim) or 이 과장님 (I gwajangnim), is perfectly polite.

Under the Revised Romanization, they would be transcribed Gim, I and Bak. But the rules leave surname spelling to be set separately, and long-used spellings like Kim, Lee and Park can still be used. People often choose their own preferred spelling for their names, so the same surname can be romanized differently by different people.

Yes. When registering a birth in Korea, the Chinese characters allowed in names are limited to an official list of 'characters for personal names' (인명용 한자). Parents usually pick characters with good meanings from this list. The list is set by Supreme Court rules and can change. Registering a name in Hangul only is also possible.

Names built from Chinese characters carry a meaning for each syllable, such as 'wise,' 'bright' or 'peaceful.' The same sound can mean different things depending on the character chosen. Asking 이름이 무슨 뜻이에요? (ireumi museun tteusieyo?), 'What does your name mean?' often leads to an interesting story.

Yes. Surnames like 남궁 (Namgung), 제갈 (Jegal), 선우 (Seonu), 황보 (Hwangbo) and 독고 (Dokgo) have two syllables. They are rare but real. So a four-syllable name may have a two-syllable surname. If you're unsure, simply ask the person which part is their family name.

Foreign names are written in Hangul to sound close to the original, with the Loanword Orthography as the standard. Spellings can vary in practice; 'Emma' might appear as 에마 (Ema) or 엠마 (Emma). Asking a Korean friend to write your name in Hangul makes a nice keepsake. Official documents rely on the name in your passport.

Some Koreans adopt an English name because foreigners may find their Korean names hard to pronounce. It is common at international companies, English academies and when living abroad. Still, many people appreciate it when you use their Korean name. The simplest approach is to ask how they'd like to be called.

Name order often flips on English forms, so it's easy to mix up. Put the family name in the 'Surname' field and the given name in 'Given name.' Two-syllable given names may be written as one word or with a hyphen, so follow the passport spelling. Bookings and airline tickets must match the passport exactly.

Yes. With court approval, Koreans can change their given name, a process called 개명 (gaemyeong). People apply for many reasons, such as a name being hard to pronounce. Procedures and requirements are set by the courts, so check official guidance. After a change, various documents must be updated.

Yes. Some people have a one-syllable given name, making a two-syllable full name, such as 김별 (Gim Byeol) or 이솔 (I Sol). This is called a 외자 이름 (oeja ireum). They are less common than three-syllable names but not rare. People often say the full name, including the surname, when addressing them.

When a given name ends in a consonant, Koreans often add 이 (i) to make it flow more smoothly in a sentence. So 민준 becomes 민준이가 왔어 (Minjuniga wasseo), 'Minjun came.' A name ending in a vowel, like 지수 (Jisu), doesn't need it: 지수가 (Jisuga). This friendly form is used among friends or for younger people.
