Abstract: The present invention relates to an identification code processing system, an identification code processing method thereof, and an apparatus for supporting the same. The present invention supports various multi-codes for a specified object to be generated using a terminal and additional information of the object to be collected, integrated, and shared by applying the generated multi-codes online and offline. A terminal recognizes a base identification code of an object, and generates and stores or transmits multi-codes on the basis of base identification information included in the base identification code. In addition, a service apparatus classifies and stores the multi-codes transmitted by the terminal, and supports the multi-codes to be circulated in at least one network device and to be regenerated as multi-codes including various additional information.
