The invention discloses a management system for an electronic code of an electronic coupon, including an electronic code generation module, an electronic code storage module an an electronic code issuing module, wherein an electronic code generated by the electronic code generation module comprises a main code; an auxiliary code and a check code, the uniqueness of the electronic code is ensured bythe random code; Generation efficiency is improved, the electronic code storage module respectively obtains a ciphertext full text and a ciphertext index through two encryption algorithms; the security of the electronic code is ensured; and finally, the electronic code issuing module adopts a serial issuing mode for the electronic codes of the same inventory unit, so that repeated issuing is avoided, the issuing efficiency is improved, and therefore, the system realizes the closed loop of the electronic code service, guarantees the safety and high efficiency of the electronic codes to a certain extent, and is more suitable for actual application requirements. In addition, the invention further provides an electronic code management platform of the electronic coupon, and the function of the electronic code management platform corresponds to the function of the system.
