Frequently Asked Questions
How to make international calls?
To make international calls from China, first dial "00" (international access code), then dial the target country's calling code (without the + sign), and finally dial the local phone number. For example, to call a US number: 00-1-local number.
Why do some countries have multiple calling codes?
Some large countries may have multiple calling codes, usually due to historical reasons or geographical divisions. Our database displays the main calling codes. Please refer to local carrier guidance for specific usage.
