Whether you're catching up with family, making a crucial business call, or simply staying in touch with loved ones, understanding how to call China from Singapore is essential. With over 450,000 Chinese nationals residing in Singapore, robust communication ties between the two countries are vital for both personal and professional connections. 

This blog will guide you through everything you need to know about China calling codes, cost-effective calling methods, and tips for seamless communication. Whether you’re new to international calls or seeking more affordable options, we’ve got you covered. 

Direct Dial a China Number from Singapore 

The simplest way to call China is through direct dialing, whether you're calling a landline or a mobile number. Here's how to do it step-by-step. 

Steps to Direct Dialing a China Landline 

  1. Start with Singapore’s international access code by dialing 001

  2. Add China’s country code, which is 86

  3. Enter the area code of the province or city you’re calling (e.g., Shanghai is 21). 

  4. Dial the local landline number (exclude any prefixes, like 0). 

Example: To call a landline in Shanghai, dial 001 86 21 XXXXXXXX

Steps to Direct Dialing a China Mobile Number 

  1. Start with Singapore’s international access code by dialing 001

  2. Follow it with China’s country code, 86

  3. Skip the initial 0 in the mobile number and proceed with the rest of the digits. 

Example: To call a Chinese mobile number, dial 001 86 123 4567890

IDD Call to China

To make an international direct dial (IDD) call from Singapore to China, you'll need to use the correct dialing sequence and IDD prefix. This format includes the IDD prefix, China's country code (86), and the area code or mobile number (without the leading 0).

Dialing Format:

[IDD Prefix] + 86 + [Area Code or Mobile Number]

For example, to call a landline in Shanghai (area code 21), you would dial:

001 86 21 XXXXXXXX

If you’re calling a Chinese mobile number (e.g., 138-1234-5678), you would dial:

001 86 13812345678
