To call Indonesia from Singapore
How To Call Indonesia From Singapore?
Calling Indonesia from Singapore might seem complicated at first, but it’s actually quite simple when you follow the correct sequence. From dialing Singapore’s exit code to adding Indonesia’s country code and area code, every step matters. Whether you’re reaching out to Jakarta or Bali, this quick guide will show you exactly how it’s done.
1. Dial the Exit Code
To begin, you must dial Singapore’s exit code. It is the number that signals your phone is about to make international calls.
- The standard IDD call code is 001.
- Some service providers use alternatives like 008, 018, or 019.
Example: If you’re using Singtel, the full string begins with 001.
2. Add Indonesia’s Country Code
Next, add Indonesia’s country code: 62.
This step is essential to route your call correctly to the destination.
Worth mentioning, this code is also referred to as the Indonesia code number, the Indonesia phone code, or the +62 area code.
3. Add the Area Code for Indonesian Landlines
If you’re calling a local landline number in Indonesia, you need the correct area code.
For landlines, it’s: exit code + country code + area code + local Indonesian call number
| City | Area Code | Sample Number |
|---|---|---|
| Jakarta | 001 62 21 XXXX XXXX | |
| Bali | 001 62 361 XXXX XXXX | |
| Surabaya | 001 62 31 XXXX XXXX |
Remove the leading ‘0’ from any Indonesian landline area code. So, if the area code is 021, remove 0 and then dial.
4. Remove “0” to Dial Mobile Number
For Indonesian mobile numbers, remove the leading 0 of the mobile number. You can choose to write either Singapore’s exit code for international dialing or dial +62.
Hence, the correct format will be: 001 or +62 + Indonesian Mobile Number without leading 0
Example: 0812 3456 7890 ? +62 812 3456 7890 or 001 62 812 34567890
Now you’re ready to call Indonesia!

Best Alternatives To Make Calls To Indonesia
There’s no shortage of ways to reach contacts in Indonesia from Singapore, but not every option is built for how you work. Here’s a quick and to-the-point breakdown to help you pick what actually fits:
1. VoIP Services (like CallHippo)
If you’re running a business, freelancing, or managing a remote team, VoIP is definitely your smartest bet. You get crisp, reliable call quality, pay-as-you-go pricing, and pro tools like call recording, analytics, and CRM integrations. These cloud-based tools make staying connected effortless and keep your calls looking polished and professional.
Expert Insight:
Home networks often have firewalls, NAT, or SIP ALG enabled by default, which can hamper VoIP traffic. This causes those random one-way calls or dropped connections. For a quick solution, disable SIP ALG or switch your router to bridge mode for clean, uninterrupted calls.
2. Calling Cards
Calling cards are old-school, but they are still used by a selected group of people. They are fine for a one-sided call, but the hidden fees, expiry dates, and bad quality make them an unsuitable option for businesses. If you’re willing to call clients, skip these.
3. Social Apps
WhatsApp, Telegram, and other social platforms are great for casual chats and free calls with loved ones or friends. But let’s be real — they can miss on call quality, and you won’t find business essentials like call logs or CRM integrations here.
4. Wi-Fi Calling
Wi-fi calling is handy for personal calls when your mobile signal’s weak. It lets you use your existing number over Wi-Fi, but it falls short for international business use. Furthermore, there are no advanced features, no reporting, and no flexibility.
5. Computer Apps
Tools like Skype, Zoom, and MS Teams ace at video meetings and group chats. Do you need solid call quality and screen sharing? Then these apps can be your saviour. But for Local business numbers and full call management? They are not a perfect match. Although they’re ideal for occasional calls, for daily business ops, VoIP platforms can definitely beat them.
Tips to Ensure High-Quality & Affordable Calls
Placing international calls is easy, but doing it well takes a bit of strategy. A poor connection or mistimed call can waste both money and opportunity. Whether you’re calling a client, partner, or friend in Indonesia from Singapore, these quick tips will help you keep calls clear, professional, and budget-friendly.
1. Save Indonesian Numbers in the Correct Format
Always store contacts as +62 [area code or mobile prefix] [number]. It saves time and prevents failed calls.
2. Be Mindful of Time Difference
Indonesia operates across three time zones: GMT+7, GMT+8, and GMT+9. Check the local time before calling to avoid inconvenient hours.
3. Avoid Peak hours
Make sure you are choosing the best time to call Singapore and avoiding early morning, late nights, and pick hours. Scheduling calls during off-peak hours can substantially amplify your conversion rate.
4. Check Your Internet Connectivity
A strong, stable connection ensures clear audio, whether you’re using VoIP apps or mobile data. Test your speed or switch to Wi-Fi for important business calls.
