Shipping setups can involve many moving parts. This guide outlines common issues and how to resolve them effectively.
📦 Courier option not showing at Checkout
If the courier shipping method is not visible at checkout, verify your checkout form configuration:
If you're using a checkout editor, ensure that the postal code field is marked as mandatory.
The courier method requires a valid postal code to appear. If this field is optional or missing, the courier option will not be shown to customers.

📦 Venipak Error: "Parcel Number Already in Use"
If you're receiving an error stating that the parcel number is already in use, adjust your settings as follows:
Go to your Store Settings in the Partner System → Shipping tab.
Open Venipak settings.
Under the last used parcel number, insert a new number that:
Contains 7 digits
Starts in the millions (e.g.,
2000001,3000001,4000001, etc.)
If You Have Multiple Stores in the Partner System:
Assign unique parcel number ranges for each store:
Store 1: Start from
3000001Store 2: Start from
5000001Store 3: Start from
7000001
This helps prevent conflicts between parcel numbers across stores.
