Where do I find the shortend codes for this call and are they required. We do not tract this information or what we have does not map to what CA has under our account. Thanks
If you go into your account and go to Sales > Shipping > Account Shipping Carriers, there is a link on the left to see the underlying codes for the Carriers and Classes that you have enabled in your account. They are also listed on this SSC page, though that page cannot include any custom ones you've created. You can see the ones you've enabled including your custom ones by using that link in your account.
