The opening of these centers came as a result of the cases of missing person and lost because of the large numbers of the visitors, especially children, during the Ziyarat of millions, especially Ziyarat Arba'een of Imam al-Hussayn (peace be upon him) that is the peak. So the opening of these centers is to reduce this phenomenon.
These centers are working together with one another, with other centers established by the holy shrine of Imam al-Hussayn (peace be upon him) and the missing centers close to the area between the two holy shrines or the general center to guide the missing.
