In the last line of the mailing address, write the postal code. Usually, postal codes are located after the names of cities or regions, separated by commas. For example, Zhangjiang Town 123, Pudong New Area, Shanghai, with zip code of 20 12 10. If you don't know the zip code, you can get it through various channels. You can consult your local post office, use the online postcode query tool or search through the Internet.

For international mail, postal codes are usually marked after country codes and separated by commas. For example, NY 1000 1 in new york, USA. In short, when filling in the postal code, you need to fill it correctly according to the regulations in your area to ensure that the mail can be delivered accurately. If in doubt, you can consult your local postal agency to get accurate postal code information.
Postal code arrangement rules
1, numerical code: most countries and regions use numerical code as postal code, which usually consists of several digits. Each number represents a specific region or postal department, such as city, urban area, county, etc.
2. Geographical arrangement: Postal codes are usually arranged according to geographical location, and adjacent areas usually have similar postal codes to facilitate the distribution and delivery of mail. The principle of postal code arrangement is to keep the codes of adjacent areas continuous as far as possible.
3. Coding level: The postal codes of some countries and regions adopt multilevel coding system, which is subdivided step by step from large area to small area. For example, in the postal code arrangement of China, the first two represent provinces or municipalities directly under the central government, and the last two represent cities, counties, districts, towns and so on.
4. Special coding: Some countries or regions may have special coding rules. For example, Canada's postal code uses a combination of letters and numbers, while Britain's postal code consists of letters and numbers alternately.
