PROBLEM TO BE SOLVED: To provide a container seal tag automatically recognizing a seal number and confirming a sealing. SOLUTION: The container seal tag has a seal body 22 with a radio circuit 27 transmitting the seal number so that a radio antenna installed at the place of the passage of a container can receive the seal number of the container, a sleeve 23, in which an operating wiring 30 for the radio circuit 27 is arranged and which is projected from the seal body 22, and a rod 32 capable of sealing an open-close door for the container by insertion and clamping to the sleeve 23. The container seal tag is constituted by cutting the sleeve 23 together with the operating wiring 30 and stopping the transmission of the seal number when the sealing of the open-close door is released. The seal number is recognized automatically through the radio antenna by such a container seal tag 21 while the sealing is confirmed automatically by the presence of the transmission of the seal number.
