Why is Shopify changing the address after the customer input it correctly.

[angelam78]

I’m having a real problem. This is the third order that we have gotten where Shopify seems to be populating the wrong address after the customer inputs the correct one. I reached out to Shopify and they were telling me it had something to do with the all in one discount app, but this does not seem correct. I just had a customer get back to me and say their shipment was being returned to sender because on the shipping label, it says Louisiana instead of California. The customer input the correct address. How does it end up going to a different state? Shopify has not been super helpful on this.

Hey, @angelam78.

Thanks for reaching out and bringing this to our attention.

If the shipping address is being changed during checkout, then it's possible that the issue is due to the feature for validating shipping addresses. While this feature is enabled by default, you can disable this feature using our guide here: Validate shipping addresses at checkout.
