Field help (AMINZIP)

This field is used to specify the length of the postal code on which the control will be based.
The value: "0" means that the control is carried out on the whole length.
This is a useful feature for some countries, like the United States, where postal codes can contain a suffix identifying a district or a building, for example, in dense urban areas.
Thus, if the postal code is entered using the following format: 5#[-]4#, and the control applies to the first 5 characters only, the town/city corresponding to the postal code made of the first 5 characters will be the one to be submitted when no record corresponding to the full code can be found.
