If an order needs to be contained in a single shipment but is too large or too fragile to fit into a single box, create a multi-package shipment.
A multi-package shipment is a single shipment that contains multiple boxes. The shipment will consist of a master tracking number with child tracking numbers for any additional labels. ShipStation allows you to configure each box with its own weight, dimensions, and insurance settings.
Not Supported by All Carriers
If the multi-package icon is not present for the selected carrier, use the Create Another Shipment option to create additional labels after you create the first shipment.
To create a multi-package shipment:
Click the plus sign + next to the Package drop-down in the Configure Shipment Widget.
ShipStation will open the Multi-Package Shipment editor.
If the + is not present next to the package drop-down, that means the selected carrier does not support multi-package shipments.
Set the dimensions, weight, and insurance option for the first package.
Click Add Package to add another package, or click Duplicate to add a package with the same shipping options.
Repeat step 3 to add as many packages as you need. Click the down arrow to add multiples of 5, 10, or 15 packages at once.
Check the box to Save New Package Set if this is a package configuration you'll use again.
Click Save Packages.
The Configure Shipment Widget will show the number of packages for this shipment next to the package drop-down menu.
To modify the packages on this shipment, click the plus sign + to reopen the Multi-Package Shipment editor.
Click Create + Print Label to print all associated labels for the multi-package shipment.
Multi-package Tracking Numbers
While each package will have its own tracking number, only the master tracking number will appear in the Shipments tab's Tracking # field.
