A communication apparatus and an ID packet recognition method thereof are provided. The communication apparatus includes an RF module, a down converter coupled to the RF module and a detector coupled to the down converter. The RF module receives an RF signal. The down converter down converts the RF signal in response to a channel select signal to generate a converted signal, wherein the channel select signal controls the down converter to alternately sweep a plurality of scan trains during a scan frame, and each of the scan trains comprises a plurality of channels. The power detector determines whether the RF signal comprises an ID packet according to the converted signal corresponding to the channels of the plurality of scan trains. The communication apparatus and the ID packet recognition method thereof can execute call scanning or inquiry scanning in a relatively quick way by executing a rapid scanning process and thus reduce power consumption. 种通信装置与识别封包的辨认方法。通信装置包含：射频模块，用于接收射频信号；下转换器，耦接于射频模块，用于响应信道选择信号而下
