Sino Korean numbers

The Sino Korean numbers are derived from the Chinese numerals (Sino is a prefix meaning Chinese).

Numbers 0-10

Number	Pronunciation	Hanja
0	영1	零
1	일	一
2	이	二
3	삼	三
4	사	四
5	오	五
6	육 / 륙2	六
7	칠	七
8	팔	八
9	구	九
10	십	十

1. For phone numbers, '공' is used instead of 영, i.e. 010-1234-5678 is 공일공 일이삼사 오룩칠팔.
2. 육 is used when it's just the number '6' or if it is the first syllable, i.e. 육십 (60). Otherwise it is 륙.

Numbers 11-99

For the numbers above 10, you form them by counting the number of 10's (십) you need, followed by the remaining digits.

• 11 = 10 + 1, so 십일 (ten one)
• 15 = 10 + 5, so 십오 (ten five)
• 20 = two 10s, so 이십 (two ten)
• 50 = five 10s, so 오십 (five ten)
• 99 = nine 10s + 9, so 구십구 (nine ten nine)

• For the numbers between 10,000-99,999 you form them by counting the number of 10,000s (만) you need, followed by the remaining digits.

Number	Pronunciation	Hanja
100	백	百
1,000	천	千
10,000	만	萬
100,000	십만	十萬
1,000,000	백만	百萬
10,000,000	천만	千萬
100,000,000	억	億

Pronunciation note

• Any time 6 is preceded by 10 (like 16 or 56), the combination is always pronounced as '심뉵'. This is because 6 is 육 if it's in the first syllable and 륙 elsewhere, so 심륙 → 심뉵.
