"From now on, we announce tasks of mechanical engineering review for the Unit 21 expedition members of the remote education university," North Korea's state-run Pyongyang Radio announced on Sunday.
"Number 69 on page 602, number 79 on page 133, number 18 on page 216," the broadcast said.
A total of 70 sets of such five-digit numbers were read out twice, Yonhap News Agency reported.
Pyongyang Radio last aired a similar broadcast on March 24.
It was the 31st such broadcast since North Korea resumed the Cold-War era spycraft on June 24, 2016, amid escalating inter-Korean tensions.
It had suspended such coded broadcasts in 2000.
