Postal codes in Monsilva

Postal codes (Monsilvan: 邮递区号, Pinyin: Yóudì qūhào) in Monsilva is a system of three + one + two (six) digits used by Shanhua Post. The first three digits are known as the "District code" (区代码). Although the last two digits of the district code were mostly randomly assigned geographically, the first digit (known as the "primary digit" (主数字)) is determined by the state:

• 1 - Amking and Huachang
• 2 - Donguan and Zaixian
• 3 - Leibo and Luhai
• 4 - Meixian
• 5 - Maguan
• 6 - Xiaogu
• 7 - Weishi and Wuzhong
• 8 - Bazhong and Shaoyu
• 9 - Nanyan and Xishanjia

After the first three digits is a dash symbol (-) followed by another three digits. These next three digits are divided into two sections. The first of the three digits is the "County code" (县代码), which can be any number from 1 to 7, depending on the number of counties within each district. Multiple counties across the country can have the same code, but only one county per district can have the same code. The final two digits are the municipality identifier. Just like the county code, the municipality identifier can be the same for multiple municipalities, but each county can only have one municipality code.

The nature of these post codes mean that every state has a postal code ending in -101 but there is only one postal code in the entire country that ends with -701, -702, -703 or -704 (all located within Fuzhou County, Luhai)
