1, find the correct postal code.
Please make sure that you have accurate postal code information before filling in the postal code. You can get the postal code in many ways, such as querying the postal service website, using the postal code query tool or consulting the local post office. Make sure to get the latest postal code corresponding to your area.
2. Fill in the local postal code.
Usually, when filling in the postal address, the postal code should be placed in the last line of the address, after the city, county and country. In international mail, the postal code usually precedes the country name.
Step 3 use the correct format
The format of postal codes varies from country to country. Postal codes in some countries include 5 digits, while postal codes in other countries may include more digits or letters. Please make sure to fill in the postal code in the correct format, and don't miss or enter any numbers or letters by mistake.
4. Pay attention to the accuracy of postal code.
Pay special attention to the accuracy when filling in the postal code. Incorrect numbers or letters may result in the mail not being delivered to the destination accurately. Please check and check the postal code carefully to make sure it is correct.
5, update the postal code
Postal codes may be updated with time and region changes. If you move or send mail to a new place, please make sure to update the relevant postal code information. This can prevent the mail from being sent by mistake or delayed.
