This error occurs when the UPS billing account number used for a shipment does not match the shipper account number configured in Swap. It is a carrier account configuration issue that requires support assistance to resolve.
Error message
"PaymentInformation/Prepaid/BillShipper/AccountNumber must be the same shipper number as Shipper/ShipperNumber — ups-standard-nl"
What this means
The billing account number on the shipment does not match the UPS shipper account number configured in Swap. This is a UPS billing configuration issue and cannot be resolved by updating the shipment.
How to fix it
Do not retry the label — retrying without fixing the configuration will not resolve the error.
Contact support and ask them to check the UPS billing account and shipper number configuration.
Once the configuration has been corrected, regenerate the label.
If the issue continues
Contact support with the RMA ID, the error message, and the UPS service name (for example, ups-standard-nl).
