Thailand Phone Number Format

Understanding the Thailand phone number format is crucial when you’re trying to call or set up communication in the country.

• +66-XX-XXX-XXXX (International format)

When dialing from abroad, the leading ‘0’ is dropped and replaced with the Thailand country code, which is +66.

Thailand Country & Area Codes

Common Thailand Phone Number Examples

Here are some Thailand phone number examples across different types to help you understand the structure of telephone numbers in Thailand:

1. Local Number

Used primarily for landline connections within specific regions, local Thai telephone numbers follow a simple format. These typically begin with a one-digit area code, such as ‘2’ for Bangkok. When calling from abroad, you must use Thailand’s international dialing code.

Local numbers are tied to geographic areas and are ideal for fixed-line communication within Thailand.

2. Toll-Free Number

Toll-free numbers in Thailand begin with 1800 or 1600 and are free for the caller, making them popular for customer support and service hotlines. These numbers are accessible both locally and through international calls, depending on the provider’s setup.

These numbers offer businesses a way to connect with customers without charging them, though access via international dialing may vary.

3. Mobile Number

The most widely used Thai phone number type, Thai mobile numbers start with prefixes like 06, 08, or 09. They are not geographically tied, offering flexibility and mobility. When dialing internationally, replace the leading 0 with Thailand’s international dialing code, +66.

Thai mobile numbers dominate the market due to high smartphone penetration and are essential for international calls, messaging apps, and business communication.
