Error in Shipping (FedEx Carrier) Error Message: "Shipper's account number should not be less than 9 digits and greater than 12 digits."

Problem:

When the Carrier Pay Method is set to Prepaid, the FedEx account number in the Carrier Details section is either too short, too long, or incorrectly formatted.

Cause:

FedEx requires the shipper’s account number to be between 9 and 12 digits. If the number falls outside this range or includes invalid characters, the shipment will fail.

Solution:

1. Update Carrier Account in Admin:

   • Go to the Admin panel.

   • Navigate to Carrier Configurations.

   • Select the Federal Express carrier.

   • Verify and update the Account Number field with the correct FedEx account (must be 9–12 digits).

2. Update the Delivery:

   • Retrieve the delivery from the Shipping page.

   • Ensure the updated carrier account number is reflected.

   • Confirm all other shipping details.

3. Retry Shipping:

   • Save the changes and attempt to ship again
