Briefing
The Instituto Nacional de Estadística (a state statistical agency) published the final electoral register for the parliamentary election on 29 November 2026 on 9 October 2026. It lists 38,728,356 eligible voters; 1,615,127 citizens who have reached voting age since the last election could vote in a parliamentary election for the first time. A total of 35,958,711 eligible voters are resident in Spain and 2,769,645 are Spaniards registered abroad.
According to the Instituto Nacional de Estadística, overseas voters are concentrated mainly in Argentina, France and the United States; 524,852 eligible Spaniards are registered in Argentina. At regional level, the province of Madrid has the largest number of eligible voters registered abroad, followed by Barcelona and A Coruña. The institute’s official table details the distribution of eligible voters by province and constituency.
The Oficina del Censo Electoral will send polling cards and other documents to all eligible voters in two separate mailings. For eligible voters living abroad, the agency gives 21 to 26 November 2026 as the period during which documents will be available at consular offices. According to notices from the Instituto Nacional de Estadística, voters registered abroad do not need to apply in advance to be included in the final register; the agency also draws attention to the deadlines for appeals and corrections.
Publication of the register sets the statutory administrative procedures in motion: municipalities and consulates must announce the inspection and claims periods, and those affected can check their entries and, if necessary, challenge them within the prescribed deadlines. The figures and dates set out here are based on official information from the Instituto Nacional de Estadística dated 9 October 2026 and supplementary notices from the Oficina del Censo Electoral.
