What's the difference between Guangzhou and Shanwei?

The difference between Guangzhou number and Shanwei number is mainly reflected in the administrative division code, fixed telephone area code and the first digit of mobile phone number. These differences are caused by different administrative divisions and different distribution of operators in different regions.

The administrative division code of Guangzhou is 020, and that of Shanwei is 0660. This means that when you make a local call or send a text message, the phone numbers in Guangzhou and Shanwei will be different.

Therefore, when using a fixed telephone to make a call, users in different regions need to use different area codes when making a call.
