The invention discloses an encoding identifier bit storage method, which belongs to the field of logistics management. The method comprises the steps of setting coordinate axes which correspond to a warehouse at the warehouse, dividing the interior of the warehouse into a plurality of storage bits along the coordinate axes, sequentially setting ascending or descending identifiers for all the storage bits along the directions of the coordinate axes, combining the identifiers of the same storage bit on the different coordinate axes, setting separators among the identifiers of the different coordinate axes for separation, and forming codes for identifying the storage bits. The method can improve the scalability of the codes of the storage bits, improve the management and the application precision of the storage bits, improve the using efficiency of the storage bits, be easy to understand the storage bits during the manual operation and reduce the errors, the encoding strategy with non-fixed-length can improve the flexibility of processing the codes of the storage bits of a logistics information system, and the length of the codes is reduced, thereby facilitating the storage and the printing of encoding data of the storage bits of the logistics information system.
