This invention discloses a dynamic processing method and system for qualification codes. Dispatched codes are transmitted to corresponding number generating stations by host devices and are displayed by the number generating stations, then, electronic devices of users are connected to the host devices by the dispatched codes obtained by scanning, the qualification codes are requested, one of a plurality of un-dispatched qualification codes is dispatched by the host devices to the electronic devices after the qualification codes are successfully requested, and when some of the qualification codes are not dispatched, new dispatched codes are dispatched to the corresponding number generating stations so as to be scanned next time; in addition, the host devices can be sequentially arranged and shunted into each of qualification examination stations by virtue of the qualification codes. Therefore, qualification can be synchronously and dynamically obtained by a plurality of persons at a plurality of sites, and the flow can be dispersed, so that the qualification obtaining time is shortened, and the awkward situation of a long queue on a single site can be avoided.
