Understanding how to say numbers in Korean is crucial for everyday communication, whether you’re shopping, telling time, or exchanging phone numbers. Unlike English, Korean uses two distinct number systems: Sino-Korean numbers, which are derived from Chinese, and Native Korean numbers.
Each system has specific contexts in which it is used, making it essential to learn both. This guide will provide a detailed explanation of both systems, their usage, and common mistakes, equipping you with the knowledge to confidently use numbers in Korean.
This article is designed for learners of all levels, from beginners to advanced students, who want to improve their fluency and accuracy in Korean.

Definition: Korean Number Systems
Korean utilizes two primary number systems: Sino-Korean numbers (Hanja-derived) and Native Korean numbers (indigenous to the Korean language). Each system has distinct origins, pronunciation, and specific contexts in which they are used. Understanding these differences is crucial for accurate and fluent communication in Korean.
Sino-Korean numbers are derived from Chinese and are used for counting money, dates, phone numbers, addresses, and measurements. They are generally used for larger numbers and more formal situations. The numbers are constructed by combining units, tens, hundreds, and thousands.
Native Korean numbers are primarily used for counting objects, age, and time (hours). They have a more limited range, typically up to 99, but are essential for everyday interactions. Native Korean numbers are often used with counter words, which specify the type of object being counted.
Structural Breakdown
Sino-Korean Structure
The Sino-Korean system is based on multiples of ten and uses specific words for units, tens, hundreds, thousands, and so on. The numbers are constructed by combining these elements in a straightforward manner.
This system is highly logical and relatively easy to learn once you grasp the basic building blocks.
Here’s a breakdown of the core Sino-Korean numbers:
- 0: 영 (yeong) / 공 (gong)
- 1: 일 (il)
- 2: 이 (i)
- 3: 삼 (sam)
- 4: 사 (sa)
- 5: 오 (o)
- 6: 육 (yuk)
- 7: 칠 (chil)
- 8: 팔 (pal)
- 9: 구 (gu)
- 10: 십 (sip)
- 100: 백 (baek)
- 1,000: 천 (cheon)
- 10,000: 만 (man)
To form larger numbers, you combine these elements. For example, 11 is 십일 (sip-il), which literally means “ten one”. 25 is 이십오 (i-sip-o), “two ten five”. 156 is 백오십육 (baek o-sip-yuk), “one hundred five ten six”.
The structure is consistently based on placing the larger units before the smaller ones.
Native Korean Structure
The Native Korean system has a more limited range, primarily used for numbers up to 99. It also uses specific words for units and tens, but the structure differs slightly from the Sino-Korean system.
Some numbers also undergo phonetic changes when used with counter words.
Here’s a breakdown of the core Native Korean numbers:
- 1: 하나 (hana)
- 2: 둘 (dul)
- 3: 셋 (set)
- 4: 넷 (net)
- 5: 다섯 (daseot)
- 6: 여섯 (yeoseot)
- 7: 일곱 (ilgop)
- 8: 여덟 (yeodeol)
- 9: 아홉 (ahop)
- 10: 열 (yeol)
- 20: 스물 (seumul)
- 30: 서른 (seoreun)
- 40: 마흔 (maheun)
- 50: 쉰 (swin)
- 60: 예순 (yesun)
- 70: 일흔 (ilheun)
- 80: 여든 (yeodeun)
- 90: 아흔 (aheun)
To form numbers between 11 and 19, you combine 열 (yeol) with the unit number. For example, 11 is 열하나 (yeol-hana), “ten one”. 15 is 열다섯 (yeol-daseot), “ten five”.
For numbers between 21 and 99, you combine the tens number with the unit number, such as 스물하나 (seumul-hana) for 21 (“twenty one”) and 아흔아홉 (aheun-ahop) for 99 (“ninety nine”).
It’s important to note that the numbers 하나 (hana), 둘 (dul), 셋 (set), and 넷 (net) often change to 한 (han), 두 (du), 세 (se), and 네 (ne) respectively when used before counter words. This phonetic change simplifies pronunciation and is a common feature of the Korean language.
Types and Categories
Sino-Korean Numbers
Sino-Korean numbers are used in a wide range of contexts, including:
- Counting money: When stating prices or amounts of money.
- Dates: Specifying years, months, and days.
- Phone numbers: Reciting phone numbers digit by digit.
- Addresses: Indicating building numbers and addresses.
- Measurements: Expressing units of length, weight, and volume.
- Minutes and Seconds: When telling time.
- Mathematical calculations: In mathematical equations and expressions.
These numbers are essential for formal communication and situations requiring precision. Their consistent structure makes them relatively straightforward to use once the basic numbers are memorized.
Native Korean Numbers
Native Korean numbers are primarily used in the following contexts:
- Counting objects: Specifying the quantity of items.
- Age: Stating a person’s age.
- Time (hours): Indicating the current hour.
- Counting people: Although counter words are essential here.
While their range is limited, Native Korean numbers are crucial for everyday interactions and expressing quantities. The phonetic changes that occur before counter words add a layer of complexity, but mastering these changes is essential for natural-sounding speech.

Usage Rules
Sino-Korean Usage Rules
Sino-Korean numbers follow specific rules that govern their usage. These rules are essential for accurate and natural-sounding Korean.
It is helpful to remember them and practice them often.
- Money: Always use Sino-Korean numbers when stating prices or amounts of money.
- Dates: Use Sino-Korean numbers for years, months, and days.
- Phone Numbers: Recite phone numbers using Sino-Korean numbers.
- Addresses: Use Sino-Korean numbers for building numbers and addresses.
- Measurements: Use Sino-Korean numbers for units of length, weight, and volume.
- Minutes and Seconds: When telling time, use Sino-Korean numbers for minutes and seconds, but Native Korean numbers for hours.
For example, to say “The price is 5,000 won,” you would use Sino-Korean numbers: “가격은 오천 원입니다 (gageogeun ocheon wonimnida).” To say “My phone number is 010-1234-5678,” you would use Sino-Korean numbers for each digit: “제 전화번호는 공일공 – 일 이 삼 사 – 오 육 칠 팔입니다 (je jeonhwabeonhoneun gong-il-gong – il-i-sam-sa – o-yuk-chil-pal imnida).”
Native Korean Usage Rules
Native Korean numbers also have specific usage rules that must be followed to ensure accuracy and fluency. These rules are especially important when using counter words.
- Counting objects: Use Native Korean numbers when counting objects, always with a counter word.
- Age: Use Native Korean numbers when stating a person’s age.
- Time (hours): Use Native Korean numbers when indicating the hour.
Remember that the numbers 하나 (hana), 둘 (dul), 셋 (set), and 넷 (net) often change to 한 (han), 두 (du), 세 (se), and 네 (ne) respectively when used before counter words. For example, to say “one person,” you would say “한 명 (han myeong)” and to say “two books,” you would say “두 권 (du gwon).” To say “I am 25 years old,” you would say “스물다섯 살입니다 (seumul-daseot salimnida).” To say “It’s 3 o’clock,” you would say “세 시입니다 (se siimnida).”

Advanced Topics
Large Numbers
Understanding large numbers in Korean requires knowledge of units beyond 만 (man). Korean groups numbers in units of 10,000, which differs from the English system of grouping in thousands.
This can be confusing for learners, so careful attention is needed.
Here are some key terms for large numbers:
- 만 (man): 10,000
- 십만 (sip-man): 100,000
- 백만 (baek-man): 1,000,000
- 천만 (cheon-man): 10,000,000
- 억 (eok): 100,000,000
- 조 (jo): 1,000,000,000,000
To express large numbers, combine these units. For example, 50,000 is 오만 (o-man), 2,000,000 is 이백만 (i-baek-man), and 100,000,000 is 일억 (il-eok).
Mastering these large number terms will greatly enhance your ability to understand and communicate about large quantities.
Counter Words
Counter words are essential in Korean when counting objects. They specify the type of object being counted and must be used with Native Korean numbers.
Choosing the correct counter word is crucial for accurate communication.
Here are some common counter words:
- 개 (gae): General objects
- 명 (myeong): People
- 마리 (mari): Animals
- 권 (gwon): Books
- 병 (byeong): Bottles
- 잔 (jan): Cups
- 대 (dae): Vehicles, machines
- 장 (jang): Flat objects (paper, tickets)
- 켤레 (kyeolle): Pairs (shoes, socks)
For example, to say “three people,” you would say “세 명 (se myeong).” To say “five books,” you would say “다섯 권 (daseot gwon).” To say “two bottles of water,” you would say “물 두 병 (mul du byeong).” Learning and correctly using counter words is a key aspect of mastering Korean numbers.
