South Korea at a glance
The numbers and facts you need before you dial.
What is the country code for South Korea?
+82 is the code that routes a call into Korea. Place it right after your own exit code to reach any landline or mobile on the peninsula.
Korean numbering is "open": a domestic trunk 0 leads into either an area code — 02 for Seoul, the shortest in the country — or the nationwide 010 mobile prefix. That trunk 0 is purely local plumbing; strip it the moment you dial internationally, and Seoul's 02 collapses to a lone 2 behind +82.
Code +82 was assigned to South Korea by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to South Korea.
How to call South Korea from anywhere
Three parts, in order: your exit code, then 82, then the Korean number with its leading 0 shaved off. Get those in sequence and the call lands anywhere from a Gangnam office tower to a fishing port in Busan.
Full example: +82 02 XXX XXXX — drop the local leading 0 when calling from abroad.
South Korea phone number format explained
The open plan does the heavy lifting here. Every domestic number wears a trunk 0; area codes run 2–3 digits, with Seoul's 02 standing alone as the only code that's a single digit once the 0 comes off. Mobiles ignore geography entirely and ride the same 010 prefix from Jeju to the DMZ.

South Korea mobile network prefixes
The prefix after +82 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
SK Telecom (SKT)
mobiles on 010; SKT is South Korea's largest mobile carrier.
KT (KT Corporation)
mobiles on 010; international exit code 001.
LG U+
mobiles on 010; international exit code 002.
South Korea time zone
Korea runs on KST, UTC+9, twelve months a year — the clocks never spring forward, so once you've done the math it stays done. Sitting nine hours ahead of London puts Seoul firmly into "tomorrow" for most of the Americas.
An East-Coast US evening (19:00–22:00 ET) lands in the Korean breakfast-and-commute hours. From Western Europe, dial early — 07:00–10:00 CET catches Seoul mid-afternoon, before the office empties.

Common mistakes when calling South Korea
Bijna elke mislukte internationale oproep is een formatteringsprobleem, geen netwerkprobleem.
Trying to read the carrier off the number
Korea's 010-for-everyone rule means the prefix tells you nothing about SKT, KT or LG U+. Stop guessing the network from the digits.
Leaving the trunk 0 in place
Seoul is +82 2, never +82 02.
Hunting for a mobile area code
there isn't one; every handset is 010 nationwide.
Dialing 1588 / 1577 / 1566 service lines from overseas
these popular Korean hotlines are usually domestic-only and won't connect internationally.
Confusing 001 and 002 with inbound codes
those are Korea's OUTBOUND carrier prefixes, used to call out of the country, not to reach it.
Applying daylight-saving math
KST holds at UTC+9 all year.
Tips to reduce the cost of calling South Korea
Route calls over VoIP or a virtual number rather than paying carrier IDD tariffs.
Where the call allows it, ring a landline
fixed-line termination usually undercuts mobile.
Calling from inside Korea? Pick a discount outbound prefix like 00700 or 002 instead of the default.
Selling into Korea? A local DID puts your business one domestic-rate call away for every customer.

South Korea +82 — FAQ
Why does every Korean mobile start with 010?expand_more
Korea consolidated all mobile networks onto one prefix back in 2004, so SK Telecom, KT and LG U+ subscribers all carry 010 — the carrier is invisible in the number.
What makes Seoul's area code special?expand_more
02 is the only single-digit area code in the country; behind +82 it shrinks to a bare 2, e.g. +82 2 XXXX XXXX.
How do I call Seoul from the US?expand_more
Dial 011, then 82, then 2, then the eight-digit subscriber number — the domestic trunk 0 is dropped.
Can I tell which network a Korean number is on?expand_more
No — number blocks are split among the operators internally, so the digits never reveal SKT, KT or LG U+.
What are the 001 and 002 codes I keep seeing?expand_more
They're Korea's outbound carrier prefixes (KT and LG U+) for calling abroad — not codes you'd use to reach Korea.
Why won't my call to a 1588 number connect from overseas?expand_more
Korea's 1588 / 1577 / 1566 business hotlines are typically domestic-only and don't route internationally.
Does Korea ever change its clocks?expand_more
No — it stays on KST (UTC+9) all year, with no daylight saving.
Can I run a +82 Seoul number without being in Korea?expand_more
Yes — MCM issues local +82 DIDs that forward to wherever your team works.
