Usps Response Error
Usps Code -2147219498
Description Please enter a valid ZIP Code for the sender.
I can not figure this one out for the life of me. I have my super administrator username (in Joomla) assigned a valid zip code, but can not get past this error message in the shopping cart.

Joomla 2.5.7
Virtuemart 2.0.10
Virtuemart AIO 2.0.10

Hello,

The ZIP code should be only numbers. It is the one set in your shop configuration.
There is also a tutorial: http://extensions.virtuemart.net/all-tutorials/8-shipment/6-installation-and-configuration-of-usps
