A computer-implemented method for mapping between part numbers that are based on different part numbering schemes includes receiving a first part number associated with an item, the first part number associated with the item being defined according to a first part numbering scheme. A database is searched for one or more second part numbers that are associated with the item and also cross-referenced to the first part number associated with the item, the one or more second part numbers associated with the item being defined according to one or more corresponding second part numbering schemes. In response to identifying the one or more second part numbers associated with the item, a database is searched for a third part number that is associated with the item and also cross-referenced to at least one second part number associated with the item, the third part number associated with the item being defined according to a third part numbering scheme, the first part number associated with the item being mapped to the third part number associated with the item through the at least one second part number associated with the item.
