The invention relates to a method of generating simple identification codes based on serial numbering conversion, comprising: extracting original serial numbering of a ticket through a reading device, storing the original serial numbering into a memory module and dividing into at least two segments, performing numbering conversion process on at least one segment to obtain the converted color code, character and digital information of the identification code, outputting and printing the color code, the character, and the digital information of the identification code onto a surface of the ticket. According to the method of generating simple identification codes in the ticket system based on serial numbering conversion, length of the code is furthermore shortened on the basis of ensuring uniqueness in the range of the code, and identification feather of the code is enhanced, which is convenient for memory and usage, wherein a name uniquely corresponding to the ticket is generated, the problems that simple secure identification of identify of the ticket and counterfeit deterrence when a real time system is not used, are solved, thereby being convenient to read, memorize and operate, and realizing process is fast and flexible, working performance is stable and reliable. application range is wide.
