Water resources zoning coding rules:

• A hierarchical coding structure is adopted, and the code format is ABBFFSY.
• Where A represents the first-level water resources zoning, BB is the second-level zoning number, and FF is the third-level zoning number.
• S and Y represent the sequential numbers of the fourth-level and fifth-level zoning respectively. If there are more than 9, English letters are used in a progressive manner.

Groundwater functional zone coding rules:

• The code format is ABBPPRRC-1CT SNN.
• ABB represents the first three digits of the water resource division, and PPRRCC represents the administrative division code.
• T and S represent the categories of the primary and secondary groundwater functional areas, respectively.

Code: A12B34C, where A represents the primary water resource division; 12 is the secondary division number; B34 is the third-level division code; and C is the fourth-level division identifier.
