How to Call Indonesia: Country Code, Dialing Steps & Cost Guide

Wondering how to call someone in Indonesia? It sounds simple until you’re staring at a phone number and wondering which digits to dial.

This guide breaks down how to call Indonesia from the US, Canada, the UK, and Australia. You’ll learn the +62 country code, how to format Indonesian numbers, the exact dialing steps, and what can affect international calling costs.

Before You Call Indonesia: 3 Things to Check

A couple of things are worth checking before you even open your dialer.

1. Is it an Indonesian mobile or landline number?

Indonesian mobile numbers start with an 8 right after the +62 country code. Landlines use city-based area codes instead, so the structure looks completely different depending on which one you’ve got.

Say you’re holding a mobile number; it might read +62 812 XXX XXXX. A landline in Jakarta looks more like +62 21 XXXX XXXX.

2. Can your phone make international calls?

Many carriers require you to switch on international calling first, sometimes through an app, sometimes by calling support. If you’re dialing through a business phone system, check whether that system needs international permissions turned on separately.

3. Are you making one call or many?

If you’re trying to reach family once in a while, your regular mobile plan is probably fine. But if it’s business, and you’re doing this more than a handful of times, it’s worth comparing what your carrier charges against a VoIP option.

What Is the Indonesia Country Code?

Indonesia’s country calling code is +62

+62 is Indonesia’s country code. That’s the number every international call to Indonesia starts with, no matter who you’re calling or where you’re calling from. The plus sign is just shorthand most smartphones recognize for “insert international access code here”; on older phones, you’d type an actual exit code instead, which we’ll cover in a minute.

One mix-up worth avoiding: +62 is not an area code. It applies to the whole country. An area code like 021 only covers Jakarta.

What does +62 replace?

Inside Indonesia, people dial numbers starting with a 0. That’s the domestic format. Once you’re calling from outside the country, remove the domestic leading 0 and add +62.

So a number you’d dial as 0812-XXX-XXXX at home becomes +62 812-XXX-XXXX when you’re calling it internationally. What comes after the country code depends on whether you’re dealing with a mobile number or a landline.

Indonesian Phone Number Format

People get tripped up here more than anywhere else. The format can vary, so check whether you’re calling a mobile or fixed-line number.

I. Indonesian Mobile Number Format

Mobile numbers fall into ranges starting with 8. Written domestically, they carry a leading 0, something like 08XX XXX XXXX. Drop that 0, slot in +62, and you’ve got the international version: +62 8XX XXX XXXX.

Here’s something worth knowing, though. Not every Indonesian mobile number has the same number of digits. There’s some variation built into the system, so don’t expect a fixed count every time.

II. Indonesian Landline Format

Landline numbers run on a different logic entirely. Each city or region gets its own area code, sometimes called kode wilayah in Indonesian documentation. Dial one domestically, and you’d punch in 0, then the area code, then the local number. Strip the 0 for international calls and keep everything else.

Subscriber number length shifts here too, depending on which city’s numbering plan you’re working with.

Example: converting a number to international format

Take a Jakarta landline written as 021-XXXX-XXXX. Calling it from abroad, you’d write it +62 21 XXXX XXXX. The 0 in front of 21 just disappears; nothing else changes.

This same conversion applies whether you’re working with a mobile number or a different city’s landline. Once the pattern clicks, you won’t have to think twice about it again.

How to Call Indonesia: Step-by-Step

This is probably why you clicked into this article. Here’s exactly what to dial.

A. General International Dialing Format

The basic formula:

• Dial: International access code + 62 + Indonesian number without the leading 0

Step 1: Dial your country’s international access code, such as 011 or 00.

Step 2: Dial Indonesia’s country code, 62.

Step 3: Enter the Indonesian phone number without its leading 0.

On a smartphone, skip the access code entirely and use the plus sign:

On most smartphones, you can enter + instead of manually entering the international access code.

B. How to Call Indonesia from the USA

Step 1: Dial 011 to indicate an international call.

Step 2: Dial Indonesia’s country code, 62.

Step 3: Enter the Indonesian number without its leading 0.

That 011 is just the exit code used across the US phone network; it’s not part of Indonesia’s number. It just flags the call as international. Smartphone users can skip straight to +62 and the number.

C. How to Call Indonesia from Canada

Canada uses the same numbering plan as the US, so the steps match exactly:

Step 1: Dial 011.

Step 2: Dial Indonesia’s country code, 62.

Step 3: Enter the Indonesian number without its leading 0.

D. How to Call Indonesia from the UK

The UK’s exit code is different:

Step 1: Dial 00 to start an international call.

Step 2: Dial Indonesia’s country code, 62.

Step 3: Enter the Indonesian number without its leading 0.

Or, again, if you’re on a smartphone, just dial +62 followed by the number.

E. How to Call Indonesia from Australia

On a mobile phone, you can normally use +62 instead of the international access code.

Step 1: Dial 0011 to start an international call.

Step 2: Dial Indonesia’s country code, 62.

Step 3: Enter the Indonesian number without its leading 0.

Mobile vs Landline Examples:

Reaching a friend’s mobile might look like +62 812 XXX XXXX. Calling a business landline in Jakarta looks more like +62 21 XXXX XXXX. Figure out which type you’re dealing with first; everything else follows from there. Landline numbers often vary in length, while mobile phone numbers are always 10-12 digits long and begin with an 8 as the mobile prefix.

Indonesian Area Codes by City

What are Indonesian area codes?

Area codes point to a specific region for landline numbers. They’ve got nothing to do with the country code, and they only apply to fixed lines; mobile numbers use their own separate ranges instead of anything city-based.

Here’s a selection of common geographic area codes (not a complete list of Indonesian fixed-line codes).

These codes only work for landline calls. A mobile number doesn’t follow this table.

Emergency and Business Numbers in Indonesia

Indonesia’s emergency number: 112

Indonesia has a single emergency number service, 112, but it is not yet available in every region. By the end of 2025, 185 local governments had implemented it, and additional regions continued to launch it in 2026. If you’re in Indonesia, check whether 112 is available in your specific area before relying on it.

Other emergency/service numbers

Indonesia has several designated emergency access numbers for different types of assistance.

Calling Indonesia: Cost Comparison

Cost comparison for calling Indonesia at a glance:

A. Traditional mobile/carrier calls

Rates swing a lot between carriers. Some bundle international minutes into your plan for a lower cost. Others just charge a flat per-minute rate that adds up fast if you’re calling often.

B. VoIP calls

VoIP routes calls over IP networks rather than traditional circuit-switched telephone networks. Depending on the provider, destination, and plan, it can offer competitive international calling rates. Pricing isn’t the same everywhere, though. Some VoIP providers charge per minute; others fold minutes into a flat monthly plan.

C. Calling apps

Internet calling apps use a reliable internet connection instead of eating into mobile minutes. For app-to-app calls, both people generally need to use the same compatible service. And your call quality is only as good as your internet that day; a shaky connection means a choppy call, and poor connectivity can affect call quality.

What affects the final cost?

A handful of things decide what you end up paying:

• Your carrier and calling plan
• Whether you’re calling a mobile number or a landline
• Which provider you’re using
• How long the call runs
• VoIP versus a traditional plan
• Roaming charges versus standard international rates

There’s no method that’s cheapest across the board. It really depends on your specific situation, so it’s worth comparing a couple of options before you settle on one.

Best Time to Call Indonesia

Indonesia’s three time zones

This part surprises a lot of people. According to Indonesia’s Meteorology, Climatology, and Geophysical Agency (BMKG), Indonesia isn’t in one time zone; it’s split across three:

• WIB (Western Indonesia Time): UTC+7
• WITA (Central Indonesia Time): UTC+8
• WIT (Eastern Indonesia Time): UTC+9

Major city examples:

Jakarta sits in WIB. Bali and Makassar run on WITA. Cities further east, like Jayapura, are on WIT.

Recommended calling window

Skip the idea of one universal “best time” and just check the zone for the city you’re actually calling. For business calls, aim for their normal working hours, and don’t forget to account for your own country’s daylight-saving shifts if that applies to you. A mistake people make constantly is assuming the whole country runs on Jakarta time. It doesn’t.

Calling Indonesia for Business: Volume and Reliability

A. Choose the right calling method

A regular mobile plan works fine for the occasional call. For frequent or multi-user business calling, compare a regular carrier plan with VoIP or a business phone system based on cost, capacity, and features.

B. What matters for high-volume calling?

If your team is calling Indonesia regularly, keep an eye on:

• Call capacity and how many concurrent calls you can run
• Call quality and uptime
• Caller ID behavior
• Call routing options
• Call recording, where it’s legally allowed
• Analytics and reporting
• Coverage for the specific destinations you need
• Account limits and how transparent the pricing actually is

VoIP doesn’t automatically mean better call quality. That comes down to your network, the provider’s infrastructure, and how well the call gets routed.

C. Check international calling restrictions

Before signing up with any provider, confirm the basics.

• Do they actually support Indonesia as a destination?
• Do they cover both mobile and landline numbers, or just one?
• What’s the per-minute pricing actually like?
• Does international calling need separate activation?

Getting these answers upfront solves most problems before they even happen.

D. When a virtual number makes sense

If your business needs centralized calling, several users on the same system, or better call routing overall, a virtual number through a business phone provider like Dialaxy can help with that. No hidden fees, and it helps you stay connected.

It won’t automatically build trust with local contacts or guarantee people pick up more often, but it does give your team a lot more control over how international calls get handled.

Common Mistakes When Calling Indonesia

1. Keeping the leading 0

Something like +62 08XXX is wrong. That extra 0 needs to go once you’ve added the country code.

2. Using +62 and the domestic number unchanged

Adding +62 while keeping the domestic leading 0 creates an incorrectly formatted international number.

3. Confusing +62 with an area code

+62 covers the entire country. Codes like 021 or 022 only apply to specific cities.

4. Assuming all Indonesian numbers have nine digits

Not accurate. Digit count shifts depending on whether you’re looking at a mobile number or a landline, and which region it belongs to.

5. Calling the wrong Indonesian time zone

With three zones in play, double-check before dialing, especially for anything business-related.

6. International calling is blocked

If the call won’t connect, check your carrier settings first, then confirm international calling is actually turned on for your account, then check your dialing format. If you’re using a VoIP app, check your internet connection too.

Ready to Call Indonesia?

Knowing how to call Indonesia is straightforward. Once you know the country code and the leading-zero rule, calling Indonesia stops being a guessing game.

Match the number type to the right format, pick a calling method that fits how often you’re actually calling, and you’re set, whether that’s reaching family back home or running business calls for your team.
