Last month, the two Koreas each removed almost a dozen guard posts near their border.
They need to officially verify it's been done, which they're planning to do on Wednesday.
Ahead of that, North Korea has been setting up yellow flags along the Military Demarcation Line to mark where officials will meet.
Seoul's Defense Ministry says each side's inspection teams will meet up with guides from the other.
From there, they will move to where the guard posts used to stand.
The South Koreans will visit the North Korean guard posts in the morning,... and the North Koreans will go to the South Korean ones in the afternoon.
