Why does the text message received by Apple's mobile phone have +86 in front of it?

+86 is the country code of China. The country codes determined by the State Power Union are divided by geographical location and time zone, just like the domestic telephone area codes such as 02 1 Shanghai and 0 10 Beijing.

Generally, you can also add two zeros in front. For example:

Country code country code

Malaysia 0060 Indonesia 0062

Philippines 0063 Singapore 0065

Thailand 0066 Brunei 00673

Japan 008 1 Korea 0082

Vietnam 0084 North Korea 00850

Hong Kong 00852 Macau 00853

Cambodia 00855 Laos 00856

China 0086 Taiwan Province Province 00886
