<P> There is no formal process for voter registration for South Korean citizens . All citizens will be automatically listed in the voters' list upon each election date . A domestic in - absentee vote was ceased and citizens can visit any residents' center (주민 센터) and vote in advance during the weekend before the actual election date . </P> <P> However, citizens either temporary visiting or permanently residing abroad must register for an overseas in - absentee ballot in order to vote . Voting can be done in Korean overseas missions . </P> <P> Voter registration in Sweden is automatic and based on the national population register, Folkbokföringsregistret, administered by the Swedish Tax Agency, where all citizens and residents of Sweden are included . Each person is assigned a ten digit national identification number, which include the person's date of birth . The register is used for tax lists, voter lists, membership in the universal health care system, public insurance, official record of residence, and other purposes . Permanent residents shall be recorded in this register even if they are not citizens but enjoy right of residence, and their citizenship status is indicated in the register . Changing the address in the central register automatically notifies all other public bodies (for example the tax district for local taxation, the social security authorities, the conscription authorities) and certain trusted private ones (e.g. banks and insurance companies), making the administration of a move of residence very simple . </P> <P> All eligible voters receive a letter in the mail to their registered address of 30 days prior to election day, in Sweden or abroad, which shows the date, time and local polling place, always on a Sunday, normally in September each 4 years . Polling may also be done anywhere in the country at various early voting stations determined by the local Election Committee or at a Swedish Diplomatic mission, all to facilitate for the voters . To vote in person a recognized photo identity document is required, or a confirmation by someone with proper identification . The voting card letter is not compulsory to bring as it is possible to print a copy of it, but it reduces waiting time . For people with difficulties to move, like elderly, hospitalized or imprisoned, there are ambulant voting stations and the possibility to vote as an absentee through a proxy, that can be a family member, caretaker, prison guard or other person in a normal relationship with the voter . Those living on the country - side can vote with their postman and those staying abroad are allowed to vote through mail with the material provided by a diplomatic mission . Elections through Internet are not yet implemented, although most other registry related services are available, like leaving a tax return . The Local Election Committee, that manages the electoral roll and oversees safe vote counting and reporting, is appointed by each County Administrative Board and all work is transparent, as Swedish authorities by default must follow the principle of transparency, but the actual vote of each individual is kept secret . All absentee and early voting ballots are sent physically to the registered local polling station for counting and double checking the voter's identity with the electoral roll eliminating any risk of double voting . </P>
