Topic summary

Goal: Include the customer’s phone number (collected at checkout for “Local delivery”) on the packing slip.

Context: During Local delivery checkout, a phone number is required. In the admin order view, that number appears under “Delivery instructions.” On the packing slip, custom “special delivery instructions” text shows correctly, but the phone number that’s auto-populated into that area does not appear.

Tried: Referencing {{ delivery_method.instructions }} in the packing slip template, but this variable does not contain the phone number.

Need: The correct variable or method to access the Local delivery phone number and render it on the packing slip.

Assets: A screenshot is provided showing the phone number displayed under Delivery instructions in the order page.

Status: Unresolved; seeking guidance on which field/liquid object exposes this phone number for packing slip customization.

When customers checkout using the “local delivery” method, they are required to enter a phone number. This phone number appears on the order page (that I can see) under “delivery instructions”. This phone number is not appearing on the packing slip. When I add special delivery instructions to an order, the text is being displayed but the phone number that’s being populated into that area is not.

Does anyone know how I would access this to add to a packing slip? Note that it is not shown in {{ delivery_method.instructions }}.
