To call China from Thailand, the phone number should be dialed in the following way in English (using the international dialing code and area code):
1、国际冠码（International Access Code）: Thailand’s international access code is +66.
2、区号（Area Code）: China’s area codes vary by region. For example, Beijing’s area code is 010, Shanghai’s is 021, and so on. When dialing from Thailand, you should omit the initial zero and use the full area code.
3、电话号码（Phone Number）: The specific phone number you are trying to reach in China.
So, if you are in Thailand and want to call a number in Beijing, China, you would dial: +66 (international access code for Thailand) followed by 00 (international direct dialing code) followed by 86 (China’s country code), then the Beijing area code without the initial zero (e.g., 10 for Beijing), and finally the phone number.
Please note that mobile phone numbers in China usually start with 13x, 14x, 15x, etc., depending on the service provider and type of service. When dialing from abroad, you should also include these digits at the beginning of the mobile number. Also, rates and procedures for making international calls may vary depending on your phone service provider in Thailand, so it’s always a good idea to check with them for the most accurate information.
