What does this error mean? "The UPS account number provided as the payment method cannot be billed, please try another account"

UPS is rejecting the third-party or recipient account number you're billing the shipment to. This usually means UPS has placed a hold or restriction on that account.

The account holder will need to contact UPS directly to resolve it — either by calling 1-800-468-8823 or reaching out to their UPS account representative.
