# All Shipping Zones

This screen displays all Shipping Zones.

Shipping Zones are simply geographical physical address areas of all Countries and/or their States that your organization can ship Products too.

Shipping Zones can also adjust the shipping cost if some zones are more expensive to deliver too.

Shipping Zones are used by Shipping Methods (to determine if any carriers can deliver to the zone) and by shippable Products (to limit delivery areas to specific zones).

For each Shipping Zone, you can set the Base Rate, Primary Weight Rate, Secondary Weight Rate, Item Rate in order to affect the cost of shipping to a Shipping Zone. These values are used in association with the similar Properties in the Shipping Methods and Products.

NOTE: Shipping Methods can share Shipping Zones but typically do not share costs (there is a per item rate if this is required for your exceptions).
TIP: Typically Shipping Zones do not overlay each other. However, if you have complex shipping cost formulas, overlaying Shipping Zones will allow you to create many fee variations.
