The invention provides a queuing and number calling method and device. A region server is provided with a first container used for storing a queue of users who waiting for transacting business; a second container corresponding to user information is established; according to a sequence for receiving a first notification message, the second container corresponding to the corresponding user is addedinto the queue of users who waiting for transacting business; and when the second notification message sent from a business transaction device is received, the current user in the queue of users whowaiting for transacting business finishes transacting the business, and a third notification message is sent to the mobile terminal of a user corresponding to the next second container in the queue ofusers who waiting for transacting business to notify the corresponding user to transact the business. By use of the method and the device, queuing and number calling automation can be realized, and disputes brought by manual number calling are avoided. In addition, distributed system architecture is adopted, i.e., a relatively independently system which comprises the region server, the business transaction device and the mobile terminal is established for each business transaction hall, a degree of dependency for a central server is lowered, and system reliability is improved.
