A virtual route can be created for boxes. By doing this, when you select box as the package type, you are identifying oversize packages that require special handling. For example, boxes so large they require more than one delivery clerk, or so heavy they require special equipment.
Note: The following step is only for users with Admin user privileges.
Activate this functionality in the Admin Mail Preferences by selecting Allow Box Only Delivery. The check-in steps are the same as regular, except that items that you identify as a box package type will be placed in a separate Box Route on the Receiving Manifest.
