Extended data

According to reports, the current preliminary construction plan is to divide the new postal code into address identification code and short code. The former is mainly used for the unique identification of geographical location, and can be used to explain and calculate the spatial relationship with certain accuracy. The latter is convenient for people to remember and use, and the address trellis code can be simplified to a "short code" form of 5 to 6 bits.

The "new postal code" may appear in the form of two-dimensional code, which has the characteristics of multi-scale, identifiable, locatable, indexable, computable and automatic spatial correlation. When sending mail, citizens only need to select the address they want to send in the address library and send the corresponding code to the courier. The courier can enter the address code into the system to start the delivery process.
