The invention relates to an equipment identification code acquisition method and an equipment identification code acquisition device. The method comprises the steps of acquiring equipment information of current equipment; dividing the equipment information into main attribute information and additional attribute information; acquiring a static equipment fingerprint according to the main attribute information; identifying whether the current equipment is historical equipment according to the static equipment fingerprint; if the current equipment is not the historical equipment; acquiring a dynamic equipment fingerprint according to the additional attribute information of the current equipment; and combining the static equipment fingerprint with the dynamic equipment fingerprint to form a final equipment fingerprint of the current equipment, wherein the final equipment fingerprint is an equipment identification code. The equipment fingerprint acquired according to the method provided by the invention can solve the problem about how to achieve both stability and difference of the equipment fingerprint, and thus the equipment in a network can be more accurately positioned and identified.
