The South Korea country code is +82 — reaching the world's 13th-largest economy + 52 million Koreans across 17 administrative divisions, plus ~78 million mobile subscriptions across KT (Korea Telecom), SK Telecom + LG U+. Home of KakaoTalk (97% of Koreans), Samsung, LG + the world's fastest 5G network.
South Korea was assigned +82 by the ITU in 1949, placing it in zone 8 with most of East Asia. Here's the structure behind every Korean phone number + the unique mobile dialing rules.
South Korea has used the +82 country code since 1949, when the ITU placed it in zone 8 alongside Japan +81, China +86, Vietnam +84, North Korea +850 and Taiwan +886. The "2" suffix was the second single-digit slot in zone 8 — South Korea got a very short 2-digit code given its later economic prominence.
Korea's telecom industry is regulated by the KCC (Korea Communications Commission) + KISA (Korea Internet & Security Agency). Three mobile carriers operate: SK Telecom (~30M subs, the largest), KT Corporation (~22M, the former Korea Telecom state monopoly), LG U+ (~16M). Korea was the first country to commercially deploy 5G (April 3, 2019).
South Korea uses leading-0 area codes — but Seoul gets the shortest in the world: just <b>02</b>. Most major Korean cities use 3-digit codes (051 Busan, 032 Incheon, 053 Daegu, 042 Daejeon, 062 Gwangju). Mobile numbers all start with <b>010</b> (the universal Korean mobile prefix since 2004 number-portability reform).
Every Korean mobile starts with 010. Before 2004, each Korean carrier had its own mobile prefix (011 SK Telecom, 016 KTF, 017 SK, 018 Hansol, 019 LG Telecom). The KCC unified them all into a single 010 prefix on January 1, 2004 to enable carrier portability. Today every Korean mobile number is +82 10 NNNN NNNN internationally (11 digits domestically).
A Korean phone number in international format is written as +82 [area code without 0] [local]. For example, +82 2 6020 0000 for a Seoul landline (domestic 02-6020-0000), +82 51 1234 5678 for Busan, or +82 10 1234 5678 for any Korean mobile (010-1234-5678 domestic).
Korean mobiles always start with 010 domestically — written internationally as +82 10 NNNN NNNN. Drop the leading 0 like landlines. The "0" across all Korean numbers (02, 051, 010) is the national trunk prefix — dropped when dialing from abroad. Korean numbers vary from 9 to 11 digits domestically depending on city + line type.
+82 2 6020 0000 reaches Seoul.From Gangnam-gu in Seoul to the Haeundae beaches of Busan, every Korean number lives behind a +82. Pick the area code that matches your customer city — or grab a universal 010 mobile.
Every country uses a different international exit code before the +82 Korea country code. From any mobile, the + symbol replaces the exit code automatically — so +82 2 6020 0000 works worldwide. Always drop the leading 0 from Korean numbers (02 Seoul → 2, 010 mobile → 10) when dialing from abroad.

Major area codes: 02 Seoul (shortest in the world), 051 Busan, 032 Incheon, 053 Daegu. The full E.164 format is +82 [area or mobile prefix without 0] [local] — 11-13 digits with +82.
+82 reaches the world's most digitally-advanced consumer market — 99% smartphone penetration, 5G nationwide + KakaoTalk on 97% of Korean phones. K-pop, K-drama + K-commerce all expect +82.
KakaoTalk (97% of Koreans, 47M MAU), KakaoPay, Naver, Naver Pay, Coupang, Kakao Bank + Toss all require a +82 mobile for full feature access. Foreign numbers face KakaoTalk's friend-approval gate.
A +82 line is the cleanest single point of contact for Korean conglomerates (chaebol) — Samsung, LG, Hyundai-Kia, SK, POSCO, Hanwha, Lotte. Korean B2B buyers respond 4-5x faster to +82 callers than to foreign numbers.
A 02 prefix says "central Seoul — Gangnam, Jung-gu, Yongsan, Gangbuk". Seoul has the world's shortest area code (just "2") — reflecting its status as Korea's ITU original 1962 priority exchange. A 051 says Busan, 032 Incheon, 053 Daegu.
Korea has the world's fastest median 5G speeds (~430 Mbps), nationwide 5G coverage since 2020 + IPv6 deployment since 2014. A +82 line operates on the most-modern telecom infrastructure on Earth.
Korea runs on Korea Standard Time (KST, UTC+9) — same clock as Japan + 1 hour ahead of China. No DST adjustments (Korea abolished DST in 1988 after the Olympics). Business hours align cleanly with Japan + most of East Asia.
