ℹ️ About International Dialing
What is an exit code?
An exit code (also called an International Direct Dialing prefix or IDD prefix) signals to your local telephone network that you intend to make an international call. From Indonesia, the exit code is 00. Some countries use a "+" symbol as a universal substitute for the exit code when dialing from mobile phones.
What is a country code?
Every country in the world has a unique numeric country code assigned by the International Telecommunication Union (ITU). The country code for 🇺🇸 United States is +1. You must dial this after the exit code so the call is routed to the correct country.
Do I drop the leading zero?
In many countries, local phone numbers are written with a leading "0" (called the trunk prefix). When dialing internationally, you should omit this leading 0. For example, if the local number in United States is written as 0712-345-678, dial it as 712-345-678 after the country code.
Mobile vs. landline numbers
The same dialing format works for both mobile and landline numbers. Simply use the same exit code and country code, then enter the full local number (minus the leading zero if applicable).
❓ Frequently Asked Questions
Can I use + instead of the exit code?
Yes — on most mobile phones, pressing and holding "0" inserts a "+" symbol, which acts as a universal exit code. So you can dial +1 followed by the local number instead of using 00.
Why is my call not connecting?
Double-check that you have dialed the correct exit code (00), the correct country code (1), and the local number without any leading zeros. Also verify that your carrier supports international calling on your plan.
How much does it cost to call United States from Indonesia?
International call rates vary by carrier and plan. Contact your phone provider for current rates, or consider using VoIP services like WhatsApp, Skype, or Google Meet for free or low-cost international calls over the internet.
What is the time difference between Indonesia and United States?
United States (UTC-5) is 12 hours behind Indonesia (UTC+7). Aim to call between 9:00 pm and 6:00 am your local time to reach them during business hours (9am–6pm their time).
Do these dialing instructions work for mobile phones?
Yes, the same dialing format applies to both mobile and landline calls. Most smartphones also let you save the number with a leading "+" in your contacts, making future calls easier.
What if the number has an area code?
Include the area code as part of the local number. For example: 00 + 1 + [area code] + [subscriber number]. Drop any leading 0 from the area code if present.
