A non-transitory computer-readable memory medium comprising program instructions which, when executed by a processor, cause a computer system to:

• display a graphical user interface (GUI) on a display, wherein the GUI is configured to receive first user input and second user input;
• responsive to the first user input, by the processor:
• upload an addressee data file, wherein the addressee data file comprises a plurality of entries in a plurality of rows and a plurality of columns, wherein the entries comprise strings of text;
• determine a feature from one or more columns of the addressee data file, wherein the feature comprises a quantitative characteristic of a string of text shared by a predetermined number of entries in the one or more columns;
• associate one or more columns of the addressee data file with an address field type based at least in part on the feature;
• and display, on the GUI, an indication of the association of the one or more columns with the address field type;
• responsive to the second user input, prepare, by the processor, instructions for printing entries from the one or more columns of the addressee data file on respective postage items of a plurality of postage items as a destination address of the address field type, said preparation comprising:
• identification of a plurality of the addressees in respective rows of the addressee data file, wherein each of the plurality of the addressees has a same first address within a first column, and within a second column the plurality of addressees have non-identical addresses with respect to others of the plurality of addressees;
• selection, for each addressee of the plurality of addressees, of the respective second address, located in the second column, as a respective destination address;
• and inclusion of the respective destination addresses in the instructions for printing entries;
• and transmit, from the processor over a transmission path to a printing processor of a printing device, the instructions for printing the entries onto respective ones of the postage items;
• printing, by a printing device responsive to receipt of the instructions, respective ones of the selected destination addresses onto respective ones of the postage items.
