The Basics of International Dialing

You must understand the components of an international phone number. A successful call relies on a specific string of digits. Each part plays a vital role in routing your call. Missing one digit will result in a failed connection.

There are three main parts to the sequence. First is the exit code. Second is the country code. Third is the local number. You must dial them in this exact order.

The Australian Exit Code

Every international call from a landline needs an exit code. This tells your provider the call is leaving the country. For Australia, this code is 0011. You dial this before anything else. Mobile phones handle this differently, which we will explain later.

Thailand’s Country Code

Every nation has a unique identifier. Thailand’s country code is 66. This directs the call specifically to the Thai network. You enter this immediately after the exit code. It is the same for both landlines and mobile phones.


How to Call Thailand from a Landline

Using a fixed landline remains a common way to call. The process is strictly manual. You must punch in every code correctly.

Follow these steps for a landline call:

  • Dial 0011: This exits the Australian network.
  • Dial 66: This routes the call to Thailand.
  • Enter the Area Code: Input the city code (e.g., 2 for Bangkok).
  • Enter the Local Number: Dial the remaining digits of the subscriber’s number.

Key Rule: Thai area codes often show a leading ‘0’ locally. You must drop this ‘0’ for international calls.

Example:

To call a number in Bangkok (02 123 4567):

Dial: 0011 + 66 + 2 + 123 4567.

How to Call Thailand from a Mobile Phone

Calling from a mobile is generally easier. Smartphones have built-in features to assist with international dialing. You do not need to remember the 0011 exit code.

Follow these steps for a mobile call:

  • Use the Plus (+): Hold the ‘0’ key until a ‘+’ appears.
  • Dial 66: Enter the Thailand country code.
  • Enter the Mobile Prefix: Dial the mobile provider code.
  • Dial the Number: Enter the rest of the subscriber’s number.

Key Rule: Thai mobile numbers usually start with 08, 09, or 06. You must remove the first ‘0’ here as well.

Example:

To call a Thai mobile (081 234 5678):

Dial: +66 + 81 234 5678.


Understanding Thai Area Codes

You need the correct area code to reach landlines in specific cities. Thailand is divided into various telecommunication regions. Using the wrong code will connect you to the wrong city. Or the call might simply fail.

These codes are only necessary for fixed lines. Mobile phones have their own prefixes. Always verify the location of the person you are calling.

Common Thailand Area Codes:

City / RegionArea CodeDialing Format (after +66)
Bangkok022
Chiang Mai05353
Phuket07676
Pattaya (Chonburi)03838
Hua Hin03232
Udon Thani04242
Samui (Surat Thani)07777

Note: Always remember to remove the ‘0’ listed in the “Area Code” column. Only use the digit in the “Dialing Format” column.


Navigating Time Differences

Timing is crucial for international calls. You do not want to wake someone up in the middle of the night. Thailand is in the Indochina Time (ICT) zone. This zone is UTC+7.

Australia spans multiple time zones. This makes calculation slightly tricky. You must know your local time relative to UTC.

Sydney vs. Bangkok:

  • Standard Time (AEST): Sydney is 3 hours ahead of Bangkok.
  • Daylight Savings (AEDT): Sydney is 4 hours ahead of Bangkok.

Planning Your Call:

If it is 1:00 PM in Sydney (AEST), it is 10:00 AM in Bangkok. This is a perfect time for business. If it is 1:00 PM in Sydney (AEDT), it is 9:00 AM in Bangkok.

Business Hours:

Thai business hours are typically 9:00 AM to 5:00 PM. Call between 1:00 PM and 8:00 PM Sydney time. This ensures you catch them during their workday.


The Cost of Calling Thailand

International calls can be expensive. Traditional carriers often charge high rates per minute. These costs accumulate rapidly during long conversations.

Factors influencing cost:

  • Connection Fees: Some providers charge a fee just to connect.
  • Per-Minute Rates: These vary by provider and plan.
  • Mobile vs. Landline: Calling a mobile in Thailand often costs more.
  • Roaming Charges: Using your Aussie SIM in Thailand is very pricey.

Average standard rates can range from $0.50 to over $2.00 per minute. A thirty-minute business call could cost you $60 or more. This is not sustainable for frequent communication.

Many people look for cheaper alternatives. Prepaid calling cards were once popular. Now, digital solutions offer better value.
