South Korea numbering plan & how to dial

South Korea uses an open numbering plan under country code +82. After the country code, a 2-digit area or mobile prefix is followed by a 8-digit subscriber number, giving a 10-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing South Korea from abroad.

South Korea has 97% internet penetration and is served by 3 major mobile networks (SK Telecom, KT Corporation, LG Uplus). VoIP is permitted and regulated by Ministry of Science and ICT (MSIT) / Korea Communications Commission (KCC). The local currency is KRW and the primary language is Korean, which shape IVR prompts, SMS content, and business-hours handling.

Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized effect on answer rates.

Common mistakes calling South Korea
  • Skipping the exit code

    Reaching South Korea from the US requires the 011 exit code ahead of +82 — skip it and the call won't connect.

  • Keeping the national trunk "0"

    If a South Korea number is written with a leading 0 for domestic use, omit that 0 after the +82 country code when calling from abroad.

  • Ignoring the time difference

    UTC+9 governs local business hours in South Korea; confirm the time there before placing the call.

VoIP Regulation

Permitted — MSIT regulated

Regulated by Ministry of Science and ICT (MSIT) / Korea Communications Commission (KCC)

  • VoIP is fully permitted; providers must register with MSIT under the Telecommunications Business Act.
  • Personal Information Protection Act (PIPA) imposes strict data privacy obligations.
  • Emergency call support (112/119) is mandatory for all registered VoIP providers.

FAQ

Calling South Korea — frequently asked questions

The subscriber portion of a South Korea number is 8 digits, after the country code and area/mobile prefix. That's the part that identifies the specific line once the call has been routed to the right network.

Seoul is the capital of South Korea. A local +82 number is recognisable to callers there and nationwide, which is part of why presenting local caller ID tends to improve answer rates across the whole country, not just the capital.

Korean is the primary language in South Korea — IVR prompts, SMS copy, and support scripts should be written in it for the best response rates. Getting the greeting and menu options right in the local language is often the difference between a caller staying on the line or hanging up.

Ministry of Science and ICT (MSIT) / Korea Communications Commission (KCC) is the regulator for South Korea. Twiching routes calls in line with its rules for compliant, licensed termination, rather than relying on unlicensed grey routes that can be blocked or degraded.

Yes — since South Korea runs on UTC+9, calls can be routed to the right team based on local business hours there. That's especially useful for support or sales teams covering multiple countries across different time zones from one platform.

SK Telecom is among the largest networks in South Korea, and Twiching interconnects directly with it for Tier-1 delivery. Direct interconnects like this are what keep call quality and answer rates consistent instead of relying on lower-tier transit.
