How to Call South Korea from Abroad: A Step-by-Step Guide

To successfully connect a call to a landline or mobile device in South Korea, you must follow a strict international dialing syntax. The format is generally identical across all global carriers, structured as follows: Exit Code + South Korea Country Code (+82) + Area Code/Network Prefix + Subscriber Number.

• Step 1: The International Exit Code (IDD). Dial your local exit code. For China, USA, and Vietnam, this is typically 00 or 011. On mobile phones, simply hold the '0' key to input a '+' symbol, which acts as a universal exit code.
• Step 2: Input the South Korea Country Code. Once the exit code is entered, dial +82. This instructs the international gateway to route your call towards South Korea.
• Step 3: Drop the Trunk Code (0). Most local numbers within South Korea begin with a 'Trunk Code' (usually a leading '0'). When dialing internationally, you must drop the leading zero.
• Step 4: The Local Number. Finally, enter the unique subscriber number.

Example: To call a specific number in South Korea from abroad, the standard dialing layout looks like: 00 +82 [Area Code without 0] [Local Number].
