USPS Error returned: Error Desc: Missing value for ZipOrigination.USPS Help Context: 1000440

I'm using the included USPS plugin nopCommerce version: 3.20
I have the warehouse configured, product shipping enabled, sizes all set and weight. The plugin is configured correctly but when i try to check out I get the following error:

USPS Error returned: Error Desc: Missing value for ZipOrigination.USPS Help Context: 1000440.

Can anyone please advise what I may have missed?

Admin > Configuration > Settings > Shipping Settings
Enter your Shipping Origin

That fixed it!!! Thank you!!

I am have the same issue with one page checkout using Nopcommerce v3.70. I had this problem with the Nopcommerce multi page checkout for USPS. I have my Shipping Origin: configured but the error persists,

"USPS Error returned: Error Desc: Missing value for ZipDestination.USPS Help Context"

Does anyone have an idea as to what could cause this? I think i am losing sales because of this.
