What is Indonesia's country code?

Indonesia's country code is +62. When calling from South Korea, dial 001 62, then the area code (without the leading 0) and the local number.

Do I need to dial a different code for mobile numbers?

No. Both landlines and mobile numbers use the same country code (+62). The difference is the prefix after the country code: area codes for landlines (e.g., 21 for Jakarta) and mobile operator prefixes (e.g., 812, 821) for mobiles.

Can I call Indonesian toll-free or premium numbers from South Korea?

Most Indonesian toll-free numbers (starting with 0800) may not route correctly from abroad. Premium and special-service numbers also may not be accessible internationally. Stick to standard landline and mobile numbers for reliable connections.

How much does it cost to call Indonesia from South Korea with Sayfone?

Sayfone offers transparent per-minute pricing to Indonesia starting at 18¢/min. There are transparent pricing or surprise charges; you pay only for the time you speak.

What if my call doesn't connect?

Double-check the number format, especially the country code and area code. Confirm the contact's number is correct. If problems persist, try calling at a different time or from a different network.

KEY DIALING RULES

Important Dialing Rules for Indonesia

Follow these rules to ensure your call connects reliably.

Drop the Leading 0 from Area Codes and Mobile Prefixes

Indonesian phone numbers within the country start with 0 (e.g., 021 for Jakarta). When calling from abroad, omit this leading 0 and use the country code instead.

Mobile Numbers Start with 8 or 9

Indonesian mobile operators use prefixes beginning with 8 or 9 (e.g., 812, 821, 852, 856). These are 3-digit operator codes; use them after the country code +62.

Landline Lengths Vary by City

Indonesian landline numbers have varying lengths. Jakarta numbers (area code 21) typically have 8 digits after the area code, while other cities may differ.

Use a '+' or the Full Access Code

You can dial either +62 (plus notation) or 001 62 (using South Korea's international access code). Both formats work; choose whichever is easier for your device.

Avoid scheduling calls around local prayer times (Asr, Maghrib, Isha); Friday midday is particularly important.

TROUBLESHOOTING

Common Issues and How to Fix Them

If your call doesn't connect, try these solutions.

Call Doesn't Connect

Verify you've included the country code (+62 or 62) and dropped the leading 0 from area codes. Double-check the number format and try again. If the issue persists, confirm the contact's number is correct.

Poor Connection Quality
