Would you like to learn how to read and say Korean numbers more naturally? This page is a strong place to begin. Korean numbers show up constantly in everyday life when you talk about prices, dates, addresses, phone numbers, page numbers, measurements, and totals.

This guide walks you through Korean numbers step by step. You will begin with the most useful forms to memorize, then learn the main rules from 1 to 1000, and finally see how larger numbers are grouped and used in real contexts.

This page focuses on the Sino-Korean number system, which is the system most often used with written numerals, money, dates, minutes, addresses, phone numbers, and math.

Before you continue, it helps to know how this page labels Korean number forms. The charts use Hangul, Romanization, and Hanja so you can connect the spoken form with both modern Korean writing and the traditional character form.

• Hangul shows the normal modern Korean spelling you are most likely to see in Korean learning materials.
• Romanization shows how the Korean number is pronounced using the Latin alphabet.
• Hanja shows the traditional Chinese-character form used historically in Korean. For many numerals, these characters look the same as Japanese Kanji because they come from the same shared character tradition.
• On this page, Hanja is included as a reference, but Hangul is the most practical written form to learn first.

Every Korean Numeral You Need First

Start with the big picture. These are the main Sino-Korean numerals worth memorizing early. Most other numbers in this system are built by combining them in predictable patterns.

Number	Hangul	Romanization	Hanja	Number	Hangul	Romanization	Hanja
0	영 / 공	yeong / gong	零	21	이십일	isip-il	二十一
1	일	il	一	30	삼십	samsip	三十
2	이	i	二	40	사십	sasip	四十
3	삼	sam	三	50	오십	osip	五十
4	사	sa	四	60	육십	yuksip	六十
5	오	o	五	70	칠십	chilsip	七十
6	육	yuk	六	80	팔십	palsip	八十
7	칠	chil	七	90	gusip	九十
8	팔	pal	八	100	백	baek	百
9	구	gu	九	101	백일	baegil	百一
10	십	sip	十	200	이백	ibaek	二百
11	십일	sibil	十一	300	삼백	sambaek	三百
12	십이	sibi	十二	400	사백	sabaek	四百
13	십삼	sipsam	十三	500	오백	obaek	五百
14	십사	sipsa	十四	600	육백	yukbaek	六百
15	십오	sibo	十五	700	칠백	chilbaek	七百
16	십육	simnyuk	十六	800	팔백	palbaek	八百
17	십칠	sipchil	十七	900	구백	gubaek	九百
18	십팔	sippal	十八	1,000	천	cheon	千
19	십구	sipgu	十九	10,000	만	man	萬
20	이십	isip	二十	100,000,000	억	eok	億

Once these core forms feel familiar, the rest of the Sino-Korean number system becomes much easier to follow.

The Rules: Korean Numbers 1–1000

Main Numbers in Korean: Units and Tens

Begin with the units from 0 to 9 and the main ten, sip (십 / 十). These pieces are the foundation for a large share of Sino-Korean numbers.

Units	Hangul	Romanization	Hanja	Tens	Hangul	Romanization	Hanja
0	영 / 공	yeong / gong	零	10	십	sip	十
1	일	il	一	20	이십	isip	二十
2	이	i	二	30	삼십	samsip	三十
3	삼	sam	三	40	사십	sasip	四十
4	사	sa	四	50	오십	osip	五十
5	오	o	五	60	육십	yuksip	六十
6	육	yuk	六	70	칠십	chilsip	七十
7	칠	chil	七	80	팔십	palsip	八十
8	팔	pal	八	90	구십	gusip	九十
9	구	gu	九

After you know these, you can already read a surprising number of larger forms. Korean builds most of them in a clean, regular sequence.

Examples in Use

• Beoseu beonhoneun isip (二十) beon-ieyo. — The bus number is 20.
• Pyogeumeun sasip (四十) won-ieyo. — The fare is 40 won.
• Geu bogoseoneun gusip (九十) peiji-yeyo. — That report is 90 pages.

How Korean Builds 11–99

Korean forms numbers from 11 to 99 in a very regular way. Start with sip (십 / 十) for ten, then add the unit. The tens are formed by placing the unit before sip (십 / 十).

Number	Hangul	Romanization	Hanja
11	십일	sibil	十一
12	십이	sibi	十二
14	십사	sipsa	十四
16	십육	simnyuk	十六
20	이십	isip	二十
21	이십일	isip-il	二十一
35	삼십오	samsibo	三十五
48	사십팔	sasippal	四十八
67	육십칠	yuksipchil	六十七
99	구십구	gusipgu	九十九

That regular structure is one reason Sino-Korean numbers are often easier to learn than they first appear. Once the tens are secure, the rest of the range becomes much more predictable.

Quick pattern: [unit] + sip (십 / 十) + [unit]

Examples in Use

• Jigeum isip-il (二十一) beon beoseureul gidarigo isseoyo. — I am waiting for bus number 21.
• Geu geonmureun samsibo (三十五) cheung-ieyo. — That building is on the 35th floor.
• Uri gyosireun yuksipchil (六十七) ho-sil-ieyo. — Our classroom is room 67.

Counting 100 to 1000

Once you can count from 1 to 99, the hundreds and thousands become much more manageable. Korean forms the hundreds with baek (백 / 百) and the thousands with cheon (천 / 千).

Number	Hangul	Romanization	Hanja
100	백	baek	百
200	이백	ibaek	二百
300	삼백	sambaek	三百
400	사백	sabaek	四百
500	오백	obaek	五百
600	육백	yukbaek	六百
700	칠백	chilbaek	七百
800	팔백	palbaek	八百
900	구백	gubaek	九百
1,000	천	cheon	千

The written pattern stays consistent here, although some combinations blend in normal pronunciation. For example, 십육 is pronounced simnyuk and 백일 is often said smoothly as baegil.

Number	Hangul	Romanization	Hanja
101	백일	baegil	百一
125	백이십오	baegisibo	百二十五
242	이백사십이	ibaeksasibi	二百四十二
518	오백십팔	obaeksippal	五百十八
999	구백구십구	gubaekgusipgu	九百九十九

Examples in Use

• Hakgyoneun baegil (百一) nyeon-ui yeoksareul gajigo isseoyo. — The school has a history of 101 years.
• Jigeum baegisibo (百二十五) peijireul ilggo isseoyo. — I am reading page 125 now.
• Oneul haengsaeneun obaeksippal (五百十八) myeong-i chamseokhaesseoyo. — 518 people attended today’s event.

Large Numbers in Korean

Korean groups large numbers differently from English once numbers get bigger. Instead of moving only from thousands to millions, Korean uses man (만 / 萬) for ten thousand and eok (억 / 億) for one hundred million.

Number	Hangul	Romanization	Hanja
1,000	천	cheon	千
10,000	만	man	萬
20,000	이만	iman	二萬
100,000	십만	simman	十萬
1,000,000	백만	baengman	百萬
100,000,000	억	eok	億

This grouping matters because Korean speakers often process large figures in units of 10,000 rather than only in millions.

Number	Hangul	Romanization	Hanja
1,225	천이백이십오	cheonibaegisibo	千二百二十五
22,000	이만 이천	iman icheon	二萬二千
305,400	삼십만 오천사백	samsimman ocheonsabaek	三十萬五千四百
2,300,000	이백삼십만	ibaeksamsimman	二百三十萬

Examples in Use

• Geu dosieneun icheono-baek (二千五百) myeong jeongdoga salgo isseoyo. — About 2,500 people live in that town.
• I hoesaui wol maechureun samsimman ocheonsabaek (三十萬五千四百) won-ieyo. — This company’s monthly sales are 305,400 won.
• Geu peurojekteu yesaneun eok (億) won-imnida. — The project budget is 100,000,000 won.

The Units “Man” and “Eok” Matter

In Korean, large numbers become easier to read once you think in groups of man (만 / 萬) and eok (억 / 億). This is especially helpful when you read prices, populations, business figures, or official statistics.

Useful Notes About Korean Numbers

• Two systems exist in Korean: this page teaches the Sino-Korean system, while native Korean numbers are used in some counting situations such as hours, age, and many object counters.
• Hangul is the most practical written form: modern Korean normally writes these numbers in Hangul or Arabic numerals, while Hanja is mainly a reference or historical form.
• Large-number grouping is different from English: Korean uses man (만 / 萬) for 10,000 and eok (억 / 億) for 100,000,000.
• Sound changes can appear in speech: combinations like 십육 → simnyuk and 십만 → simman are normal pronunciation changes.

Real-Life Korean Number Examples

• I jusoneun sasippal (四十八) beon-ieyo. — This address is number 48.
• Oneureun sam-wol sibi-il (三月十二日) ieyo. — Today is March 12.
• Hoeuineun chil-si samsip-bun (七時三十分)e sijakhaeyo. — The meeting starts at 7:30.
• Jeonhwa beonhoeneun gong-il-gong (零一零)-i deureogayo. — The phone number includes 010.
• I chaegeun baegsipgu (百十九) peiji-kkaji isseoyo. — This book goes up to page 119.

Continue Learning Korean Numbers

Once you understand the main patterns, it becomes much easier to read, write, and recognize Korean numbers in real situations. Use chart pages, date lessons, time lessons, and quiz pages to keep strengthening your understanding.
