We’ve received feedback that a small number of sellers have experienced issues at Canada Post retail counters when dropping off shipments with Shippo labels. This is caused by incorrect scanning of the shipment by the postal clerk.
As Canada Post works to correct this problem, we suggest asking the postal clerk to try the following guidance from Canada Post:
For Domestic Packages:
If your domestic package gets rejected, Canada Post suggests that postal workers select "Supplier Account" as payment method.
For International Packages:
If your international package gets rejected, Canada Post's guidance is for the clerk to contact their internal Retail Help Desk for support.
If you do run into this problem, please contact us at email@example.com with the Post Office location and the tracking number of the shipment.
