Abstract: The invention includes a method for error proofing shipments where users are presented with the options of parts marking, parts verification or pack verification using an output device. A user option choice is received using an input device. If the user chooses the parts making option, then a first part number is received from the user and causes the printing of a first quantity of labels in response to the first part number. If the user chooses the parts verification option, then a second part number is received from the user, an identification symbol is scanned using a scanner to identify an identification number associated with the identification symbol, and the identification number is then compared to the second part number. An indication is provided to the user if the identification number and second part number do not match. If the user chooses the pack verification option, then a third part number and quantity is received from the user.
