How is the national electoral register created?

ODIHR Election Assessment Mission Final Report: Presidential Election, 28 January and 4 February 2018

“Elections are administered by the MoI. The Permanent Secretary of the MoI serves as the General Returning Officer (GRO). The GRO has overall responsibility for the election administration and is supported by a permanent Central Electoral Office (CEO) that has a key operational role. […] Voter registration is maintained by the Civil Registry and Migration Department of the MoI. Every voter is issued a voting booklet, which can serve as identification on election day. Following legal amendments introduced after the 2016 parliamentary elections, voters can also use their regular ID cards for voting in addition to the voting booklet. Voter lists are revised and updated quarterly by the MoI and district offices and voter registration information is available for review at district offices and online. Despite voter records being linked to the civil registry, the authorities justify maintaining active voter registration by the need to verify voters’ actual place of residence.”
