Whether you contact family, manage a business, or plan a trip, knowing how to call Indonesia from the UK properly is vital. We will explore traditional methods and modern solutions. These include Telfon’s effective virtual number for Indonesia. You should always check the current time difference before dialing. A reliable online time zone converter can help.

Mastering International Dialing Fundamentals

Making an international call requires a specific number sequence. You must first signal that you are calling outside your country. Next, you indicate the destination country. Finally, you provide the local phone number. This process remains consistent. It applies to both landline and mobile phones.

The Standard Dialing Format

Every international call generally follows a clear structure:

  • Exit Code: This code tells your phone system that you are dialing abroad.
  • Country Code: This unique code identifies the specific country you want to reach.
  • Area Code: This code directs your call to a particular region or city.
  • Local Phone Number: This is the specific number of your contact.

We will break down these steps. This helps you understand the UK to Indonesia calling code journey.


Calling Indonesia from UK: A Step-by-Step Guide

Calling Indonesia from the UK demands accuracy. You must enter the correct codes. The order is also very important. Let us examine how to do this. We cover both landline and mobile phone methods.

Calling from a Landline

Using a traditional landline phone requires careful attention. Follow these steps precisely:

  • Dial the UK Exit Code: Begin by dialing 00. This is the standard international exit code from the UK.
  • Dial the Indonesian Country Code: Enter 62 next. This is Indonesia’s unique country code.
  • Dial the Area Code: Input the local area code. This directs your call within Indonesia. Do not include a leading zero if the area code has one.
  • Dial the Local Phone Number: Enter your recipient’s specific local phone number last.

Landline Call Example:

To call a landline in Jakarta, Indonesia, with Area Code 21, you would dial:

00 - 62 - 21 - [Local Phone Number]

Calling from a Mobile Phone

Calling Indonesia from a mobile phone is quite similar. It offers an added convenience for the exit code.

  • Use Plus Sign (+) or UK Exit Code: You can dial + instead of 00 on most mobile phones. The + symbol automatically functions as the international exit code. Alternatively, using 00 also works perfectly.
  • Dial the Indonesian Country Code: Enter 62.
  • Dial the Area Code: Input the specific area code. Again, omit any leading zero.
  • Dial the Local Phone Number: Enter your contact’s local number.

Mobile Call Example:

To call a mobile number in Indonesia, or a landline in Bali with Area Code 361, you would dial:

+62 - 361 - [Local Phone Number]

Or:

00 - 62 - 361 - [Local Phone Number]

Using the + symbol is often better. It makes the number universally dialable. This is true regardless of your starting country.


Demystifying the UK to Indonesia Calling Code

The country code is central to your international call. For Indonesia, this code is 62. You must always include it. It comes after your international exit code (00 or +). This code signals to the network that your call is going to Indonesia. Without it, your call will not connect. It might even go to a different country.

  • Exit Code (from UK): 00 or +
  • Indonesia Country Code: 62

These two elements are vital. They ensure you successfully initiate international calls UK to Indonesia.

What is the full dialing code for Indonesia from the UK?

The dialing code for Indonesia from the UK combines 0062 (for landlines) or +62 (for mobiles). You then add the area code. Finally, you dial the local number. The 00 or + is the UK international access code. 62 is Indonesia’s specific country code.


Essential Indonesian Area Codes

Indonesia is a vast country. It spans many islands and cities. Each major city or region has its own specific area code. You must know this code. It ensures your call reaches the correct destination. Remember to exclude any leading zeros. These might appear in an Indonesian local area code listing. For example, (021) becomes 21.

Here are some common Indonesian area codes for major cities:

City/RegionArea Code
Jakarta21
Surabaya31
Bandung22
Medan61
Semarang24
Yogyakarta274
Bali (Denpasar)361
Makassar411

Always confirm the correct area code. Ask your contact if you are unsure. An incorrect area code will stop your call from connecting.

How do I find an area code in Indonesia?

You can find an area code by asking your Indonesian contact. Alternatively, search online for “Indonesia area codes.” Or search “phone codes for [city name] Indonesia.” Many online directories provide this information reliably.

Indonesian Phone Number Format

Indonesian phone numbers, including the country code, range from 10 to 12 digits. This includes the country code, area code, and local subscriber number. Mobile numbers in Indonesia typically start with 8.

Let us look at the complete format:

[International Exit Code] - [Indonesia Country Code] - [Area Code] - [Local Number]

Example of a full number to call from the UK:

  • To a Jakarta Landline: 00 - 62 - 21 - XXXX XXXX (Local number is 8 digits)
  • To an Indonesian Mobile: +62 - 8XX - XXXX XXXX (Mobile numbers usually start with 8 and are 10-12 digits in total after the country code).

Remember to drop any leading zero from the area code. If an Indonesian source lists an area code as (021), you dial 21.
