Roscommon, Sligo, Monaghan town and Navan, Naas, Bray, and Thurles stations have lost divisional HQ status.
Gardai have confirmed the location of their new Regional and Divisional Headquarters as part of a restructuring plan implemented by Garda Commissioner, Drew Harris.
The Regions will be reduced from six to four while Divisional Headquarters will be brought down from 28 to 19.
The plan is based on population numbers, geography, projected growth and crime trends.
Seven Garda stations that are currently the headquarters for policing in their area are to lose that status under the plans.
Roscommon, Sligo and Monaghan towns have all lost the divisional headquarters status.
Also losing their divisional HQ status are the Garda stations in Navan, Co Meath, Naas, Co Kildare, Bray, Co Wicklow and Thurles, Co Tipperary.
Headquarters stations were always set to lose its status as divisional headquarters in the merged larger divisions.
