“Greece has a passive voter registration system. The MoI is primarily responsible for the compilation, certification and printing of voter lists based on the population register. The MoI also co-ordinates with local civil registries, which provide civil status updates on citizens and eliminate duplicate entries. The update of voter lists is regular and is open for public scrutiny. Political parties can receive copies of voter lists and voters can check their records and ask for corrections at any time. Political parties met with by the OSCE/ODIHR EAM acknowledged their right to access voter lists; however, they stated that they do not have sufficient human resources to fully exercise this right.”

The Ministry of Interior is responsible for the compilation, certification and printing of voter lists. However, it utilizes the data extracted from the population register.
