What an Indonesia number looks like
An Indonesian phone number in international format has three parts. The trunk 0 is removed before +62.
Landline
+62 | 21 | 12345678
Mobile
+62 | 812 | 34567890
Number format and length
After +62, Indonesian numbers contain 9-11 digits. Landlines use a 1-3 digit area code and a 6-8 digit subscriber number. Mobile numbers start with 8 followed by digits.
| Number type | Pattern | Example |
|---|---|---|
| Jakarta landline | +62 21 XXXX XXXX | +62 21 1234 5678 |
| Bali landline | +62 361 XXX XXX | +62 361 123 456 |
| Indonesian mobile | +62 812 XXXX XXXX | +62 812 3456 7890 |

Indonesia area codes, toll-free, and emergency numbers

| Bandung | 022 | +62 22 |

| Bali | 0361 | +62 361 |
| Semarang | 024 | +62 24 |
| Number type | Dialed in ID | Notes |
|---|---|---|
| Emergency | 112 | Police, fire, ambulance |
| Toll-free | 0800 | Free from Indonesian lines, not always reachable from abroad |
| Premium rate | 0900 | Can cost more than standard calls |
| Business numbers | 085 | Non-geographic business lines |
Keep in mind: 112 and 110 work inside Indonesia only. If you are outside Indonesia, call the emergency number for your current location. 0800 and 0900 numbers may not accept calls from outside Indonesia.
Cost and best time to call Indonesia

How much does it cost to call Indonesia
For business calling, Telnyx SIP Trunking gives per-minute pricing for calls to Indonesian landline and mobile destinations with usage-based pricing and a 99.999% uptime SLA. Your total cost can change based on call volume, destination type, and fees from your current provider.
| Calling method | Cost pattern | Best for |
|---|---|---|
| Mobile carrier | Plan rate or international fee | Personal calls |
| International add-on | Recurring fee plus lower per-minute rates | Repeat callers |
| VoIP or SIP | Per-minute pricing by destination type | Teams and high-volume calling |
Good to know: Ask your provider whether Indonesian mobile calls are priced differently from landline calls. They often are.
Time zones and best time to call
Indonesia spans three time zones: WIB (UTC+7) for Jakarta and Sumatra, WITA (UTC+8) for Bali and Sulawesi, and WIT (UTC+9) for Papua. For business calls, aim for 9:00 a.m. to 5:00 p.m. in the target region.
| Calling from | Offset from WIB | Best call window |
|---|---|---|
| US Central | WIB is 12 hours ahead | 8:00 a.m. to 10:00 a.m. CT |
| US Central | WIB is 13 hours ahead | 8:00 a.m. to 10:00 a.m. CT |
| US Pacific | WIB is 15 hours ahead | 6:00 a.m. to 8:00 a.m. PT |
Good to know: Time differences can shift for short periods because daylight saving dates do not match in every country.
Is calling Indonesia free
Calling Indonesia is not automatically free. It may be free if your mobile or landline plan includes Indonesia calling, if both parties use an app over data, or if a company gives you a reachable toll-free number.
WhatsApp and similar apps do not charge per minute for app-to-app calls, but your internet or roaming plan may charge for data. Business callers can use SIP Trunking with usage-based pricing for the lowest per-minute rates.
