What does the number beginning with +86 mean?

+86 is the international area code of China. On the phone or mobile phone, "+"means two zeros, so some can also write 0086.

The international area codes related to China are: China +86, Taiwan Province Province of China +886, Hongkong of China +852 and Macau of China +853.
