counting in korean numbers

Before we begin, you need to know that there are 2 ways of counting numbers in Korean.  There’s 1) the Sino-Korean system and 2) the Native Korean System.  What’s the difference? The Sino-Korean System is used for:

  • time (minutes), units of time, the names of months, counting money, saying phone numbers, counting measurements, and etc.

The Native Korean System is used for:

  • time (hours), counting objects, counting number of people, age, and for counting in general! 

You need to remember to never mix or combine Sino-Korean system with Native Korean system in when describing a number. Stick to appropriate system! Hey, but don’t worry! It’s not complicated at all!

Let’s review these numbers, okay?

My phone number is 012-345-6789.

(For saying phone numbers, you should use Sino-Korean numbers.)

  • 전화번호는 공일이삼사오육칠팔구 입니다
  • Jae Jun-Hwa-Bun-Ho-Neun Gong-Il-Ee-Sam-Sa-Oh-Yuk-Chil-Pal-Gu Ib-Ni-Da.
  • (전화번호 = Jun-Hwa-Bun-Ho = Phone number.)

Eight apples

(For counting objects, you should use Native-Korean numbers.)

  • 사과 여덟
  • Sa-Gwa Yeo-Durb Gae
  • (사과 = Sa-Gwa = Apple)
  • ( = Gae = Counting unit for objects)

Ten people

(For counting people, you should use Native-Korean numbers.)

  • 사람
  • Sa-Ram Yeol-Myung

Counting from 11 to 20 in Korean

Now, let’s go higher. Let’s count from 11 to 20.

There are 2 rules you need to remember. To count from 11 to 19…

  • For Sino Korean: Add “Sib” to the Sino-Korean numbers 1-9 that you learned in part 1
  • For Native Korean: Add “Yeol” to the Native Korean numbers 1-9 you learned in part 1

So, for example…

  •  Sino Korean: Sib + Sino-Korean Number
    • 19 is Sib-Gu
    • 15 is Sib-Oh
  • Native Korean: Yeol+ Native-Korean Number
    • 19 is Yeol Ah-Hob
    • 13 is Yeol-Saet

Counting in Korean: 21 to 30

Higher! Let’s do from 21 to 30!

Why? Because 21 to 29 require some rules as well. Very much like making numbers 11 to 19, you’re going to take numbers from part 1. Then, you’re going to add a new word in front.

There are 2 rules you need to remember. To count from 21 to 29…

  • For Sino Korean: Add “Ee-Sib” to the Sino-Korean numbers 1-9 that you learned in part 1
  • For Native Korean: Add “Seu-Mool” to the Native Korean numbers 1-9 you learned in part 1

So, for example…

  •  Sino Korean: Ee-Sib + Sino-Korean Number
    • 29 is Ee-Sib-Gu
    • 25 is Ee-Sib-Oh
  • Native Korean: Seu-Mool+ Native-Korean Number
    • 29 is Seu-Mool Ah-Hob
    • 23 is Seu-Mool-Saet

  • Ma-Ri = 마리  = Counting unit for animals
  • Five Tigers
  • 호랑이 다섯마리
  • Ho-Rang-Ee Da-Seot-Ma-Ri

Transportation. When saying the bus, train, flight, ticket numbers, you should use Sino-Korean numbers.

Counting to 100 in Korean

You’ve noticed how simple it is to start counting in Korean, right? Once you get familiar with the patterns and rules, and memorize them, it is easy. You will master in counting any numbers in Korean!

In this part, you learn how to write and pronounce any number up to 100.

So, what’s the rule for counting in Korean to 100? It’s easy. If you want to do any number between 30 and 100, just follow a very similar rule. You know how in English, you take words twenty, thirty, forty and ninety and then add numbers one to nine to make 39 or 99? Same thing.

  • Take  30, 40, 50…90.
  • Add the number from 1 to 9 that you learned in part 1.
  • This applies for both, Sino-Korean numbers and Native Korean numbers.

When saying the time [hour], you should use NATIVE-Korean numbers. When saying the time [minutes], you should use SINO-Korean numbers. ex: 09:25 (아홉시 이십오 분).

[…] To learn more about Korean numbers, check out my other lesson here. […]


this is helped me a lot, now i can practice on my number




Thank you for these, it helped a lot. My only comment is that sometimes you say to use sino-korean but you are using native korean in your examples. It’s kind of confusing if we’re trying to memorize it. But all in all, it was helpful. Maybe just edit it. Thank you!

By the way, not many native Koreans use the Sino-Korean for 18 because it sounds like a curse word with a similar pronunciation to f**k. So, if speaking with it, it’d be better to use the Native Korean.


Hello! This was so helpful, thank you!

Everything was great, but I think you mixed up native- and sino-Korean towards the end (after you have taught how to count to 100, you get us to practice telling the time).

Otherwise, this was awesome!


This helped me a bunch. Thanks ☺☺☺


It is 11:45.

When saying the time [hour], you should use Sino-Korean numbers. When saying the time [minutes], you should use Native-Korean numbers.

지금은 열한시 사십오분 입니다.
And the last line written 한글 shows hours written in Native-Korean system of numbering, so make your mind please….
