The term "ZIP Code" is used exclusively for postal codes in the United States. If your address is not in the US, then you do not have a ZIP Code.
The image that you provided shows that you are using the Quick version of the listing form. In order to set up shipping from outside the US, you must switch to the Advanced version of the listing form, which is sometimes called the "business tool."
To access this form: start with a new blank copy of the Quick listing form, then click on the link for "Change listing preferences." After you do that, the upper right corner should have a link for you to switch to the business form, where the shipping section wll let you choose which country you are shipping from.
