1. Why are There Two Counting Systems in Korean?

There are two counting systems in Korean–Sino Korean, and native Korean. You may be wondering why Koreans feel the need to use both systems–why not just use one? The answer is simple. Until 한글 (hangul) = “Native Korean Language” was invented during the 조선왕조 (joseonwangjo) = “Joseon Dynasty,” native Koreans had no alphabet of their own and had to borrow 한자 (hanja) = “Chinese characters.” This is why you still see words and yes, numbers, based on Chinese characters, which are called Sino Korean words and numbers. And with the creation of the new language system came the creation of a new set of counters, which is why you see two number systems in the Korean language. Don’t fret, however – the numbers are used in different situations. Once you get the hang of when to use which numeric system, things will get easier. And only Sino-Korean numbers are used from 100 and up, so keeping that in mind will also make it easier for you to figure out the numeric system. You can learn more about Korean numbers in our blog article but here are some quick examples.

1- Some Examples of When to Use Sino Korean Numbers

• Phone numbers: 공일공 공일공일 일이삼사 (gongilgong gongilgongil ilisamsa) = 010 0101 1234
• Bank account numbers 사일이-XXXX-XXXX (saili-XXXX-XXXX) = “412-XXXX-XXXX”
• Minutes/Seconds: 삼십 분 삽십 초 (samsip beun samsip cho) = “thirty minutes thirty seconds”
• Dates: 일월 일일 (ilweol ilil) = “January 1st”
• Money: 오천 원 (ocheon won) = “5,000 won”
• Addresses: 이십일번가 (isibilbeonga) = “21st street”
• Formal age 세 (se): 이십 세 (isip se) = “twenty years old”
• Math equations: 삼 더하기 삼은 육 (sam deohagi sameun yuk) = “3+3=6”

2- Some Examples of When to Use Native Korean Numbers

• Informal age 살 (sal): 스무 살 (seumu sal) = “twenty years old”
• Hours: 다섯 시 (daseot si) = “five o’clock”
• Number of people: 네 명 (ne myeong) = “four people”
• Number of objects: 네 개 (ne gae) = “four (items)”

2. How to Say 0-9 in Sino and Native Korean

When it comes to counting numbers in Korea, you’ll notice that there are different ways to count the same number. That’s because we have two different counting systems which are called “Sino Korean” and “Native Korean.” While native Korean numbers are used more often in general, Sino Korean numbers are used when counting money, doing math, or talking about phone numbers. When learning numbers in Korean, vocabulary mastery is very important. Check out “Korean Numbers” on KoreanClass101 to practice the numbers and pronunciation together.

Number	Sino Korean	Native Korean	Translation
0	영 (yeong), 공 (gong)	*	“zero”
1	일 (il)	하나 (hana)	“one”
2	이 (i)	둘 (dul)	“two”
3	삼 (sam)	셋 (set)	“three”
4	사 (sa)	넷 (net)	“four”
5	오 (o)	다섯 (daseot)	“five”
6	육 (yuk)	여섯 (yeoseot)	“six”
7	칠 (chil)	일곱 (ilgop)	“seven”
8	팔 (pal)	여덟 (yeodeol)	“eight”
9	구 (gu)	아홉 (ahop)	“nine”

*There’s no word to say “zero” in the Native Korean counting system. Instead, you can use 공 (gong) from Sino-Korean. Koreans also say 제로 (jero), from the English word “zero,” for counting zero.

3. How to Say 10-100 in Sino and Native Korean

This time, let’s count from 10 to 100.

Number	Sino Korean	Native Korean	Translation
10	십 (sip)	열 (yeol)	“ten”
11	십일 (sipil)	열하나 (yelhana)	“eleven”
12	십이 (sipi)	열둘 (yeoldul)	“twelve”
13	십삼 (sipsam)	열셋 (yeolset)	“thirteen”
14	십사 (sipsa)	열넷 (yeolnet)	“fourteen”
15	십오 (sipo)	열다섯 (yeoldaseot)	“fifteen”
16	십육 (sipyuk)	열여섯 (yeolyeoseot)	“sixteen”
17	십칠 (sipchil)	열일곱 (yeolilgop)	“seventeen”
18	십팔 (sippal)	열여덟 (yeolyeodeol)	“eighteen”

30	삼십 (samsip)	서른 (seoreun)	“thirty”
40	사십 (sasip)	마흔 (maheun)	“fourty”
50	오십 (osip)	쉰 (swin)	“fifty”
60	육십 (yuksip)	예순 (yesun)	“sixty”
70	칠십 (chilsip)	일흔 (ilheun)	“seventy”
80	팔십 (palsip)	여든 (yeodeun)	“eighty”
90	구십 (gusip)	아흔 (aheun)	“ninety”
100	백 (baek)	온* (on)	“one-hundred”

*온 (on) is rarely used in spoken/written language. Koreans use 백 (baek) instead. There’s a lot to go through when it comes to numbers in learning the Korean language. If you want to practice counting more with Korean numbers, check out our free Korean lesson.

4. How to Say Numbers Up to 1,000 in Sino and Native Korean

Ready to count more? Let’s try to count up to 1,000 in Korean!

Number	Sino Korean	Native Korean	Translation
200	이백 (ibaek)		“two-hundred”
300	삼백 (sambaek)		“three-hundred”
400	사백 (sabaek)		“four-hundred”

1,000	천 (cheon)	즈믄* (jeumeun)	“one-thousand”

*즈믄 (jeumeun), the native Korean word for “1,000”, is rarely used in spoken/written language. Therefore, Koreans use 천 (cheon) instead.

5. How to Say Other Big Numbers in Sino and Native Korean

Let’s continue to push ourselves and count big numbers in Korean.

Number	Sino Korean	Native Korean	Translation
2,000	이천 (cheon)		“two-thousand”

1,000,000	백만 (bangman)		“one-million”
10,000,000	천만 (cheonman)		“ten-million”
100,000,000	억 (eok)		“one-hundred-million”
1,000,000,000,000	조 (jo)	울* (ul)	“one-trillion”

*드먼 (deumeon), 골 (gol), 잘 (jal), and 울 (ul) are rarely used in spoken/written language. Use the numbers from Sino Korean.

6. How to Give Your Phone Number

The Korean mobile number looks like this: xxx-xxxx-xxxx (eg. 010-1234-5678). The number consists of mobile prefixes, followed by personal numbers. There used to be many different mobile prefixes, such as 011, 016, 018, 019, and so on. Whether you live or travel in South Korea, you’ll need a SIM card and your mobile to get around. It’s okay to just write down your mobile number and show it to a person, but it’ll come in handy if you can say your mobile number in Korean. Let’s practice how to do this. Let’s say that your number is 010-1234-5678. Firstly, Koreans use Sino Korean to tell a mobile number, so never use Native Korean numbers when giving someone your mobile number. When there are four numbers (in this case, 1234 and 5678), try to break it down into two parts: 12 and 34, and 56 and 78 (just pause one second in between). This way, the listener is going to be able to write down your mobile number a lot easier. Practice 1: How do you say 010-1234-5678 in Korean?

• 공일공* – 일이삼사- 오육칠팔 (gongilgong* – irisamsa- oyukchilpal)

*It’s not wrong to say, 영일영, but it is uncommon to say this in Korea. So try to stick to 공일공. Practice 2: How do you say 019- 5544-0099 in Korean?

• 공일구-오오사사-공공구구 (gongnilgu-oosasa-gonggonggugu)

If you want to say “My number is ~” in Korean, it’s 전화번호는 ~입니다(jeonhwabeonhoneun ~imnida). E.g. 전화번호는 공일구, 오오사사, 공공구구 입니다. (Jeonhwabeonhoneun gongnilgu, oosasa, gonggonggugu imnida.) On our website, we have a beginner lesson for “Exchanging Phone Numbers.” Feel free to check out this page as well as other free lessons for beginners.

7. Shopping – How to Say Prices

Korean money is called “원” (won) and is used only in South Korea. There are four kinds of coins being used in Korea, which are ₩10, ₩50, ₩100, and ₩500 (₩5 and ₩1 are rarely used). Also, there are four Korean banknotes which are ₩1,000, ₩5,000, ₩10,000, ₩50,000. When saying prices, we use Sino Korean, therefore it shouldn’t be too difficult for you to learn. When mentioning the prices, all you need to do is say the numbers in Sino Korean, followed by 원 (won).

8. Shopping – How to Use Numbers When Shopping

Now that you’re familiar with prices in Korean, let’s learn a number of useful phrases. In Korean, the majority of goods are fixed price; however, in places like Dongdaemun, you can certainly negotiate the price. Feel free to use any of these phrases when negotiating the price with the shopkeeper:

9. Time

Let’s learn how to say the time in Korean. But first, let’s learn how to count hours and minutes!

1- How to Count Hours

Number	Korean	Romanization	Translation
1:00	한 시	han si	“One o’clock”
2:00	두 시	du si	“Two o’clock”
3:00	세 시	se si	“Three o’clock”
4:00	네 시	ne si	“Four o’clock”
5:00	다섯 시	daseot si	“Five o’clock”
6:00	여섯 시	yuseot si	“Six o’clock”
7:00	일곱 시	ilgop si	“Seven o’clock”
8:00	여덟 시	yeodeol si	“Eight o’clock”
9:00	아홉 시	ahop si	“Nine o’clock”
10:00	열 시	yeol si	“Ten o’clock”
11:00	열한 시	yeolhan si	“Eleven o’clock”
12:00	열두 시	yeoldu si	“Twelve o’clock”

2- How to Count Minutes

Time	Korean	Romanization	Translation
10	십 분	sip bun	“Ten minutes”
20	이십 분	isip bun	“Twenty minutes”
30	삼십 분	samsip bun	“Thirty minutes”
40	사십 분	sasip bun	“Forty minutes”
50	오십 분	osip bun	“Fifty minutes”

Did you notice something? That’s right. When it comes to the time, we use Sino Korean, followed by 분 (bun), direct translation being “minute(s).” For example, if the clock reads 11:35 a.m., we can say 열한시 삼십오분 (yeolhansi samsibobun). Example: A: 지금 몇시예요? A: Jigeum myeotsiyeyo? A: “What time is it now?” If you want to review this, feel free to check out our free lesson “Telling Time” for Korean beginners on our website.

10. Calendar

1- Month

Number	Korean	Romanization	Translation
1	일월	irwol	“January”
2	이월	iwol	“February”
3	삼월	samwol	“March”
4	사월	sawol	“April”
5	오월	owol	“May”
6	유월*	yuwol	“June”
7	칠월	chirwol	“July”
8	팔월	parwol	“August”
9	구월	guwol	“September”
10	시월*	sibwol	“October”
11	십일월	sibirwol	“November”
12	십이월	sibiwol	“December”

*Did you notice that June is written as 유월(yuwol), not 육월(yukwol), and October is 시월(siwol), not 십월(sibwol)? The reason is that these two words are difficult to pronounce, so to simplify, we say 유월 and 시월.

2- How to Count Days

Counting days is easy. Say the number in Sino Korean and add 일 (il) which means “~th day” in English. For example, if you want to say 15th, in Korean it’s 십오일(siboil) (십오+일(sibo+il)). For 27th, it’s 이십칠일(isipchiril) (이십+칠일(isip+chiril)).
