Quick Ship was just updated to 2026.1 and now we are having an error message when we try to ship UPS Ground to Canada. We have always used this. I found KB0112909 but doesn’t really give much info, honestly I think it is old.
121100 The requested shipment is invalid for the shipment origin
We have a UPS Canada/Mexico ship via code for UPS ground to Canada. Maybe you need that? We’ve had that for a while though. So not sure why the 2026 upgrade would cause issues. Unless when it registered with UPS after the update it applied new requirements.
Also make sure your company information is correct in setup. We’ve had that change unexpectedly after an update.
