Managing Postal Zones

Postal zones are user-defined areas made up of custom lists of postal codes. Use postal zones to group regions that should follow the same rules for warehouse assignment and shipping policies. For example, a postal zone can represent:

• Distance Ring - An area around a warehouse that qualifies for one-day or two-day delivery.
• Proximity Cluster - Postal codes closer to Warehouse A than Warehouse B.
• Special Region - Remote areas with longer transit times or higher shipping costs.

Your carrier can provide postal code charts to help define these areas around your warehouses.

Creating Postal Zones

To create a new postal zone, follow these steps:

1. From the left sidebar, go to Settings › Shipping, and select Postal Zones.
2. In the upper right, click New Postal Zone.
3. Enter a name for the zone.
4. Select the country.
5. Enter or paste up to 50,000 postal codes.
6. Click Save.

You may create overlapping zones where a single postal code appears in more than one zone. For example, the same postal code might belong to Zone 1 for Warehouse A and Zone 2 for Warehouse B.

Editing Postal Zones

To edit a postal zone, follow these steps:

1. From the left sidebar, go to Settings › Shipping, and select Postal Zones.
2. Click the zone you want to update.
3. Update the zone name if needed.
4. Click Update Postal Codes.
5. Enter or paste the updated list of postal codes.
6. Click Save.

Changes to postal zones can affect existing shipping policies and warehouse assignments rules.

Deleting Postal Zones

To delete a postal zone, follow these steps:

1. From the left sidebar, go to Settings › Shipping and select Postal Zones.
2. Click the zone you want to delete.
3. Click the Delete button, and confirm the deletion.
