How to Call Thailand from the UK: A Guide for SMBs and Startups
Imagine you’re working with a supplier in Bangkok or checking in with your customer support team in Chiang Mai. You reach for your phone — but then pause. What’s the right way to dial Thailand from the UK? If you're an SMB or startup growing your international footprint, knowing how to place international calls properly and affordably can make a big difference. This quick guide breaks it all down: dialing codes, phone number formats, pricing tips, and how DialLink can help your business stay connected globally with ease.
What’s the Thailand Country Code?
The country code for Thailand is +66. You’ll need this every time you make a call to Thailand from outside the country.
Here’s how it works: When you dial internationally, your phone system uses the country code to route your call to the correct destination. In this case, entering 66 tells the system to send the call to Thailand.
This is essential whether you're following up with a Thai-based agency or onboarding a remote employee. A simple mistake in the number could send you somewhere completely different, or fail to connect at all.
How to Call Thailand from the UK (Step-by-Step)
Whether you’re dialing a Thai landline or mobile, the basic process is similar:
For Thai Landlines
- Dial 00 – This is the UK’s international exit code.
- Dial 66 – Thailand’s country code.
- Dial the area code (without the leading 0) – e.g., Bangkok is 2.
- Dial the local number – Typically 6 to 7 digits.
Example: Calling a landline in Bangkok 00-66-2-1234567
For Thai Mobile Phones
- Dial 00 or use + on a mobile phone.
- Dial 66.
- Dial the mobile number without the first 0, for example, 081-234-5678 becomes 81-234-5678.
Example: 00-66-81-234-5678 or +66-81-234-5678
Bonus Tip
On smartphones, you can hold the 0 key to insert a +. This acts as a shortcut for the international exit code (00 from the UK).
So instead of dialing 00-66-2-1234567, you can dial +66-2-1234567.
Common Thailand Area Codes
Here are some of the most common area codes in Thailand, along with the locations they correspond to:
| Area Code | Location |
|---|---|
| 2 | Bangkok |
| 32 | Hua Hin |
| 33 | Chonburi |
| 34 | Nakhon Pathom |

Use these codes to ensure your call is routed to the correct region.

FAQs
What country has a country code of 66?
Thailand. The country code +66 is used when dialing into Thailand from outside the country.
How are country codes used in a phone number?
Country codes help route international calls to the correct destination. When you dial internationally, you first enter the exit code (e.g., 00 in the UK), then the country code, followed by the area code and local number.
Do you need to dial a country code for mobiles?
Yes. When calling internationally, you must include the country code, whether it's a mobile or landline. Skip the local 0 that typically begins Thai mobile numbers.
How to Call Thailand?
Use the format:
- 00 + 66 + area code (no 0) + local number for landlines
- 00 + 66 + mobile number (no 0) for mobiles
- Or replace 00 with + on mobile devices.
What is the Thailand Phone Number Format?
Thai phone numbers are usually:
- Landlines: 0X-XXXXXXX (remove the 0 when calling internationally)
- Mobiles: 0XX-XXXXXXX (remove the 0 when calling internationally)
What does a country code replace?
The country code replaces the leading 0 in a local number when dialing internationally. For example, 081-234-5678 becomes +66-81-234-5678.
Why is there a + sign before international phone numbers?
The + is a universal symbol that replaces the international exit code. It's used to simplify dialing from mobile phones, automatically routing your call through the appropriate international gateway.
