Zone Hierarchies

Zone hierarchies are associated with service providers.
May be applied to all services (the carrier default) or just one service.
Used in various places in the system as a standard hierarchy of destinations.
A very powerful mechanism for rating data as well as analysing it.

Rating By Zone

Initially, the ratings system will take the destination entered in the transaction and attempt to find a rate covering that specific zone. If a match is not found, the system then attempts to place the destination within a zone hierarchy for either the current service or the carrier default.


Postcode 2020 (Mascot, NSW) has been entered into the transaction. Not finding a rate, the software will search for a containing postcode range for the current service. Not finding a postcode range, it will then try and find a containing postcode range in the default zone hierarchy for the carrier.

If it is found within a postcode range then the program will take the parent local zone and attempt to find a rate associated with that. Not found by the local zone it continues to move up the hierarchy trying successive levels until a match is found. This processing can start at any point so that the user may have entered "SYDNEY" as a local zone into the transaction.
