The data of this postal code and area code query system should be the most comprehensive (more than 60,000 items) published so far. It is accurate to the postal code and area code of streets, villages and towns. It supports fuzzy query. Just enter the name of the province, city, county or village. After finding the relevant zip code and area code, you can also check the geographical location based on the zip code or area code.
Text query does not require database support such as MYSQL. It is automatically cached when querying, and the query speed is faster the second time.
Text query efficiency is not very high and will be optimized when there is time.
