IMPORTANT RULES
South Korea Dialing Rules & Formats
South Korea follows strict number formatting. Understand these rules to avoid connection issues and ensure reliable calls.
Mobile Prefix Structure
South Korean mobile numbers begin with 01 (followed by 0, 1, 2, 5, 6, or 7). Common prefixes include 010, 011, 016. When dialing internationally, drop the leading 0 and dial just 1X.
Landline Area Codes
Landlines are assigned by region. Seoul is 02, Busan is 051, Daegu is 053, etc. Dialing from Thailand, drop the 0 and use the remaining digits.
Number Length
South Korean landline numbers are typically 8 digits (after the area code). Mobile numbers are 8 digits after the 01X prefix.
International Prefixes from Thailand
Both 001 and 007 are valid international prefixes in Thailand. Some sources note 009 is also available on certain carriers, though 001 and 007 are most common.

Calling tips
- South Korea operates on Korean Standard Time (UTC+9) year-round with no daylight saving. Thailand is UTC+7 year-round, maintaining a consistent 2-hour difference.
- Weekdays 8am–6pm KST (4pm–2am THT) are standard business hours. Plan important calls during this window.
- Early morning (7am–9am KST / 3am–5am THT) may work for urgent calls, but confirm the recipient's availability first.
- Avoid late-night calls (11pm–7am KST). South Korean business culture values punctuality and respect for off-hours.
- Weekends follow different customs: Saturday mornings are sometimes used for casual or family calls, but Sunday is typically reserved.
Business etiquette
- Introduce yourself clearly and state the purpose of the call at the beginning.
- South Korean business etiquette values formality. Use titles and formal language when calling offices or government organizations.
- Confirm the best time and contact method before placing calls to unfamiliar numbers.
- If you reach voicemail, leave a clear message with your name, company, and callback information.
- For sales or service calls, sending a brief email beforehand increases the likelihood of reaching the right person.

TROUBLESHOOTING
Common Issues & Connection Tips
Most calls from Thailand to South Korea connect reliably, but understanding potential issues helps you troubleshoot quickly if needed.
Call Won't Connect
Verify you've dialed the correct format: 001 (or 007) + 82 + area/mobile code (without leading 0) + local number. Check that you haven't accidentally included extra spaces or special characters. If dialing a mobile, confirm the 01X prefix is correct.
Unknown Number Format
If you receive a South Korean number without area code information, ask the contact to confirm whether it's a landline (which needs an area code) or a mobile (which begins with 01X). This clarification prevents misdials.
Poor Audio Quality
Audio quality depends on your internet connection (if using browser-based calling) and carrier routing. Try placing the call again or switching to a different network. If quality remains poor, consider calling at a different time when network congestion is lower.
International Prefix Issues
Thailand supports both 001 and 007 as international prefixes. If one doesn't work, try the other. Some older phone systems may not recognize 007, so 001 is the safer default.
No Answer or Voicemail
If calls go unanswered, confirm the time in South Korea (UTC+9). Calls outside business hours (8am–6pm) or on weekends may not be answered. Leave a voicemail with your name, company, and callback number.
