How to Ask Someone's Age in Korean: 몇 살이에요?

Quick answer: The safe, polite way to ask an adult's age in Korean is 나이가 어떻게 되세요? ("How old are you?" / naiga eotteoke doeseyo). 몇 살이에요? (myeot sarieyo) is the plainer version — fine for someone clearly younger than you or in a relaxed setting, a little blunt for a stranger or someone older. For someone much older, use 연세가 어떻게 되세요?

Here's the one idea to take away: in Korean, asking someone's age isn't nosiness. It's a practical question, because the answer decides how the two of you will speak to each other from that moment on — polite form or 반말, name or 오빠/언니/형/누나. Koreans ask early for the same reason English speakers ask "What do you do?" — it files the person somewhere.

Why it comes up so fast

In English you can talk to someone for a year without knowing their age. In Korean you can't really get comfortable without it. The moment two people of similar age meet, there's a small unspoken question hanging in the air: are we equals, or is one of us the older one? Until that's settled, both people stay in careful 해요체 and nobody relaxes.

So the question isn't rude. How you ask can be.

The ladder of forms

나이가 어떻게 되세요? is the one to memorize. It's literally "how does your age come out?" — indirect, which is exactly why it feels polite. Koreans use the same frame for other personal questions: 이름이 어떻게 되세요? ("What's your name?"), 연락처가 어떻게 되세요? ("What's your number?").

Put 혹시 in front to soften it further:

혹시 나이가 어떻게 되세요? Can I ask how old you are?

혹시 is the single most useful softener in Korean for a question that might be a touch personal — it's one of the words covered in this guide to 혹시, 아마 and 글쎄요.

One warning: never say 몇 살이에요? to someone clearly older than you, or to a shop owner, a colleague's boss, anyone in a service role. It isn't offensive exactly — it just lands the way "How old are you?" from a stranger lands in English, flat and a little childish.

A real exchange

Two people in their twenties, meeting at a friend's dinner. They've been talking for twenty minutes in 해요체.

A: 혹시 나이가 어떻게 되세요? Can I ask how old you are?

B: 저 96년생이에요. 그쪽은요? I was born in '96. How about you?

A: 어, 저도 96년생이에요! Oh, me too!

B: 진짜요? 우리 동갑이네요. Really? We're the same age.

A: 그럼 우리 말 놓을까요? Should we drop the formal speech, then?

B: 네, 좋아요. Yes, let's.

That last turn is the whole point of the question. 동갑 means "same age," and discovering it is a tiny celebration — 동갑이네요! usually gets a smile. 말 놓다 means to switch to 반말; if the idea of that moment makes you nervous, there's a full guide to dropping formality in Korean.

The softer version natives often prefer: 몇 년생이세요?

Among adults who look roughly the same age, a lot of Koreans skip the age question entirely and ask the birth year instead:

몇 년생이세요? What year were you born?

It feels lighter — more like comparing notes than asking for a number. And it sidesteps a real confusion: Korea officially counts age the international way (만 나이), but older Korean-style counting still floats around in everyday talk, so two people can give different numbers for the same birthday. Birth year has no such ambiguity.

If you want to be sure which system someone means:

만으로 스물넷이에요. I'm twenty-four by international count.

A gentler, chattier alternative is the zodiac animal:

띠가 어떻게 되세요? What's your zodiac animal?

Same information, zero awkwardness, and it often turns into its own small conversation.

Saying your own age

Ages with 살 use native Korean numbers: 스무 살 (20), 스물한 살 (21), 서른 살 (30), 마흔 살 (40). Note 스무 살, not 스물 살 — 스물 shortens before a counter.

• 저는 스물여덟 살이에요. — I'm twenty-eight.
• 저 서른이에요. — I'm thirty. (dropping 살 is very common in speech)
• 저는 97년생이에요. — I was born in '97.

Birth years, by contrast, use Sino-Korean numbers, read digit by digit: 97년생 is 구칠 년생.

What to say once you know

This is the part learners forget to prepare, and it's where the conversation actually goes.

• 우리 동갑이네요! — We're the same age!
• 저보다 한 살 많으시네요. — You're a year older than me.
• 제가 한 살 더 많네요. — I'm a year older, then.
• 그럼 제가 언니라고 불러도 돼요? — Can I call you 언니, then?
• 말 편하게 하세요. — Please speak comfortably (= you don't need polite form with me). Said by the younger person to the older one.
• 아니에요, 괜찮아요. — No, it's fine (= I'm comfortable speaking like this).

That last pair is a small ritual. The younger person offers 말 편하게 하세요; the older person often turns it down once with 아니에요, 괜찮아요 before accepting a little later. Don't take the first "no" as a real refusal — it's politeness, and if you offer again it usually lands.

When it goes off script

They dodge. Some people, especially women asked by a man, or anyone in a work setting, won't answer:

비밀이에요. / 맞혀 보세요. It's a secret. / Guess.

Take it lightly and move on: 아, 죄송해요. 그냥 궁금해서요. (Oh, sorry — I was just curious.) Don't push.

They ask you first. The return question is usually just ○○ 씨는요? or 그쪽은요? — "and you?" Have your own age ready in Korean so you don't stall.

You'd rather not say. You're allowed the same dodge: 비밀이에요 ㅎㅎ works, and so does a redirect — 저는 나이가 좀 많아요. (I'm a bit on the older side.)

The setting is wrong. In a job interview, with a client, with a stranger on the street — don't ask at all. The question belongs to social situations where you're trying to figure out how to talk to each other. If the relationship already has a fixed shape (customer and staff, interviewer and candidate), age isn't needed and asking looks odd. When you do need to address someone in a shop or office, titles do the work instead — and Korean has a title for almost everyone once family gets involved.

FAQ

How do you ask someone's age in Korean politely?

Say 나이가 어떻게 되세요? It's the standard polite question for an adult you've just met, and adding 혹시 at the front (혹시 나이가 어떻게 되세요?) makes it softer still. For someone clearly much older than you, switch 나이 to the honorific noun 연세: 연세가 어떻게 되세요?

Is it rude to ask someone's age in Korea?

Not in most social situations — it's a normal early question, because age determines which speech level and which titles the two of you will use. It becomes rude when you ask a much older person with the plain form 몇 살이에요?, or when you ask in a setting where the relationship is already fixed, like a job interview or a shop. If someone deflects, drop it immediately.

What does 몇 살이에요 mean in Korean?

It means "How old are you?" — 몇 is "how many," 살 is the counter for years of age. It's grammatically polite (해요체) but direct in tone, so it fits children, close friends and people clearly younger than you. For strangers and older people, 나이가 어떻게 되세요? is the safer choice.

Practice

1. You've just met a woman who looks about your own age at a friend's party. Ask her age politely, with a softener.
2. Your friend's grandmother is sitting next to you. Ask her age.
3. Say "I'm twenty-six" in Korean, two ways (with 살 and without).
4. You find out you were both born the same year. React in one short sentence.
5. She's a year older than you. Tell her so, politely.
