I still remember the first time a new hire at a Seoul office introduced himself as “Kim Minsu” and I immediately called him “Minsu” for the rest of the meeting, assuming that was his first name. He was polite about it. Everyone else in the room was not. Months later, filling out a delivery form at a different company, I watched a coworker’s package get sent back because the courier’s system had swapped her surname and given name into the wrong fields — Park had ended up in the “first name” slot and her actual given name sat where a surname should be, and the address label came out looking like it belonged to a stranger. That’s when it clicked for me that this wasn’t just a one-time awkward introduction. It’s a structural mismatch that keeps resurfacing in small, annoying ways.
Here’s the short version: in Korean, the family name comes first, then the given name. Kim Minsu means the surname is Kim and the given name is Minsu, full stop. No middle name, no comma flipping things around like a Western business card would do. It sounds simple when you write it out like that, but the confusion runs deeper than most explanations let on, and that’s really what this post is about.
The order itself: surname first, always
Korean names almost always follow a strict pattern: one-syllable family name, followed by a one or two-syllable given name. Park Jimin is Park (family) plus Jimin (given). Choi Woo-shik is Choi plus Woo-shik. It’s the same order used across China and much of East Asia, and it’s not some quirky exception — it’s the default naming convention for a huge share of the world’s population, even though English-language media treats “first name last” as if it were the strange one.
The confusion usually starts when Koreans don’t keep this order for a Western audience. A businessman named Kim Minsu might put “Minsu Kim” on his English business card specifically because he’s used to Westerners flipping it back anyway, so he saves everyone the trouble. Meanwhile his coworker in the same company keeps “Kim Minsu” order because that’s what feels correct to her. Same company, same country, two different conventions on two different cards. Nobody agreed on this as a rule; it’s just individual habit, and that inconsistency is honestly the root of half the trouble foreigners run into.
It also matters early, before you even get to surnames and syllables, because it shapes how you address someone at work from day one. In a Korean office, you rarely default to a given name at all — you use family name plus title, like Kim Bujang-nim (Manager Kim) or Park Sajang-nim (President Park), and that pattern holds regardless of how casual the office culture otherwise feels. A foreign hire used to first-name-basis workplaces might go weeks without hearing a Korean colleague’s given name spoken out loud even once. It’s not distance for its own sake; it’s just a different default for what counts as appropriately respectful.
Kim, Lee, Park: why it feels like everyone has the same last name
If you’ve spent any time in Korea, you’ve noticed it: an enormous share of the population seems to be named Kim, Lee, or Park. That’s not a coincidence or an exaggeration. Kim alone accounts for roughly one in five South Koreans, and Kim, Lee, and Park combined cover close to half the country. There are fewer than 300 surnames in total use in Korea today, compared to the tens of thousands common in a country like the United States. So when you meet three Kims in one small meeting room, that’s just statistically expected, not some strange coincidence worth a raised eyebrow.
Because those three surnames carry so much of the population on their own, Korean naming needed a second layer just to keep families distinguishable from one another, which is where “bon-gwan” (본관) comes in — essentially a clan origin tied to a specific ancestral region. Two people can both be named Kim, but one traces back to the Gimhae clan and the other to Gyeongju, and traditionally those two lines were treated as entirely separate families for purposes like marriage eligibility. It’s a layer most foreigners never even learn exists, and honestly, most younger Koreans don’t dwell on it much these days either — but it explains why “Kim” was never really one unified family to begin with, even though it looks that way from the outside.
Dollimja: the generational syllable hiding in a family’s names
Here’s a detail that rarely makes it into beginner guides: a lot of given names in Korea aren’t fully freeform. Many families use a “dollimja” (돌림자), a generational name syllable shared by siblings or same-generation cousins. So if a father names his sons Minsu and Minho, that repeated “Min” isn’t a coincidence or a matching theme he picked for cuteness — it signals they belong to the same generational rank in the extended family, often following a rotating cycle of characters written down generations earlier in a family genealogy book (jokbo).
This tradition has faded somewhat in recent decades, especially in cities, where parents increasingly pick given names purely for sound or meaning rather than lineage tracking. Still, it hasn’t disappeared, and you’ll see it plenty in older generations’ names and in family-saga dramas where a scene will casually reveal three cousins all sharing one syllable. If you ever notice two Korean siblings whose names share one syllable, there’s a decent chance it’s not a stylistic choice at all — it’s a naming system quietly doing exactly what it was designed to do.
How given names actually get chosen
Given names in Korea usually come from Sino-Korean characters (hanja), each with its own meaning, and parents — sometimes with a grandparent or a professional name-fortune teller weighing in — pick a combination believed to bring good fortune, based on the child’s birth details in the Korean lunar calendar and Five Elements theory (saju). This isn’t universal; plenty of modern parents skip the fortune-telling step entirely and just choose names that sound good together or carry meaning they personally like, sometimes in pure Korean rather than hanja at all. Names like Haneul (sky) or Bit-na (shining) are purely native Korean words with no Chinese-character basis, and they’ve become noticeably more popular over the last generation as a kind of quiet cultural statement.
Either way, the given name is rarely just decorative. Even names that sound modern and casual to an English ear usually carry a specific, intentional meaning chosen for the child — which is worth remembering the next time you’re tempted to shorten someone’s two-syllable given name into a single-syllable nickname without asking first. It can land as more casual than intended, since Koreans don’t default to nicknames the way English speakers often do with names like Michael becoming Mike.
Romanization: the same name, five different spellings
This is where things get genuinely inconsistent, even for Koreans themselves. Korean has no single, universally enforced system for converting its sounds into the Roman alphabet on personal documents. The government’s official Revised Romanization system would spell 이 as “I” and 박 as “Bak,” but almost nobody actually uses those spellings in real life. Instead, you’ll see “Lee,” “Yi,” “Rhee,” and even “Ri” all representing the exact same Korean surname, and “Park” persisting as the default English spelling for 박 despite being, by most linguists’ account, one of the least phonetically accurate romanizations still in common use. Picture an American family named Smith showing up on four different government documents as “Smith,” “Smyth,” “Smithe,” and “Smithee” — that’s roughly the scale of inconsistency Korean surnames tolerate on paper without anyone treating it as an error.
Why does this happen? Passports historically let the applicant choose their own preferred spelling within reason. Once a family settled on one spelling — often decades ago, sometimes shaped by how an immigration officer or an English teacher first wrote it down — it tends to stick across generations for consistency with older documents, even when it doesn’t match current romanization guidelines. That’s how you end up with siblings whose passports spell the same family name slightly differently, if one applied years before the other and family preferences shifted in between. It’s also how a company’s Korean-language paperwork and its English-language paperwork can list an employee’s name in two spellings that don’t obviously match unless you already know they’re supposed to be the same word.
Given names have it even worse, honestly, since there’s more room for personal preference. A given name written 정연 might appear as “Jung-yeon,” “Jeong-yeon,” or “Jungyeon” with no hyphen at all, depending entirely on what the person filled out on their own paperwork. None of these are wrong exactly — they’re just different transliteration choices for sounds that don’t map cleanly onto English spelling conventions in the first place.
Where this trips foreigners up in real life
The most common stumble happens on forms. Western intake forms ask for “First Name” and “Last Name,” and a Korean applicant has to decide, every single time, whether to put their family name in the “first name” box because it comes first in their own language, or in the “last name” box because that’s the field’s actual intent. There’s no consistent right answer that every Korean person follows, which means the same person might genuinely fill it out differently depending on the day or the form — and once that inconsistency lands in a database, it can quietly follow someone across flight bookings, bank accounts, and delivery addresses for years without ever getting fully corrected. On the flip side, foreigners looking at a Korean name on a badge or a name tag sometimes guess wrong about which part to use when addressing someone directly, calling a manager by what’s actually her family name and wondering why the room goes quiet.
And then there’s the entertainment industry, which somehow manages to make things more confusing rather than less. Korean drama and film credits often list cast and crew in Western order (given name, family name) for international release versions, while the same credits in the domestic Korean-language version keep the traditional order. Watch the same show’s opening credits in both languages back to back and you’ll see the exact same two names in reverse sequence. It’s a small thing, but it’s a fairly accurate stand-in for the whole topic: one name, two orders, both technically correct, and no sign either convention is going away in favor of the other any time soon.
FAQ
If a Korean coworker introduces herself as “Park Sujin,” which part do I actually call her?
Park is the family name, Sujin is the given name. In a formal or workplace setting, especially early in the relationship, default to family name plus an honorific or title rather than jumping straight to “Sujin” — that’s closer to how her own colleagues would address her unless you’re already on close personal terms.
Why does my friend’s passport spell his surname “Yi” when everyone else with the same Korean surname spells it “Lee”?
Both represent the same Korean character, 이. There’s no single mandatory romanization for personal names in Korea, so the spelling on a passport usually reflects whatever the applicant or their family chose at some point, sometimes decades ago, and it tends to stay fixed after that for document consistency.
I noticed two brothers with names that both start with the same syllable — is that just a family style choice?
It might be decorative, but there’s a good chance it’s a dollimja, a generational naming syllable shared among siblings or cousins of the same generation in a family. It’s an older tradition that’s becoming less common in cities but is still very much alive in plenty of families.
