This grid is used to define the geographic areas in which the service provider is capable of intervening.
It is based on a mechanism that can only be applied to some countries. In fact, this functionality is based on a certain type of post code structure.
For example, if a service provider can intervene throughout the Hauts de Seine Department (France), it is possible to enter:
Title Geographical area Country.
FR 92 Hauts de seine.
This service provider will then be suggested for any customer whose location falls within a post code starting with 92.
This method of functioning requires a structure which is slightly hierarchical giving a meaning to each letter/number in the post code.
For the countries where this functioning cannot be used, each complete post code must then be opened.
This column is used to enter the beginning of a postal code.
