About Postal Codes and Telephone Area Codes

A Postal Code (or Zip Code) is a geographic code used for mail sorting and delivery. In mainland China, it usually consists of 6 digits. Using the correct postal code helps improve the efficiency of mail and package delivery.

A Telephone Area Code is a numerical prefix used to distinguish telephone networks in different geographical areas. When making long-distance calls, you typically need to dial the corresponding area code before the local number.

Frequently Asked Questions (FAQ)

Q: Can I find information if my input is somewhat vague?

A: The tool will do its best to match your entered keywords. For optimal results, it is recommended to enter names or codes as accurately and completely as possible. If there are too many results, try using more specific keywords.

Q: Why are results sometimes displayed in tabs and other times directly in a table?

A: This depends on the complexity and volume of the search results. Tabs are used when information can be clearly categorized or presented stepwise. If the result set is relatively simple, it may be presented directly in a table.
