Do you use a "Shipper Number"? I think, but don't know for certain, but I think that's required for Commercial Rates to be returned.

On the USPS website, I don't think so and don't see one. It's just my personal USPS account I've used for many, many years.

I assume you are not referring the to USPS Web Tools User ID, which is being used in the plugin settings.
