The Oficina del Censo Electoral at the Instituto Nacional de Estadística published preliminary electoral roll data for the parliamentary election on 29 November 2026 on 9 October 2026. According to the data, 38.73 million people will be eligible to vote, around 1.26 million more than at the July 2023 election. About 440,000 of the additional entries are Spaniards registered abroad in the Censo de Residentes Ausentes .
The roll is based on changes in population registers up to 1 August 2026. Electoral rolls can be inspected in Spain from 12 to 19 October 2026 ; during this period, those affected may request corrections. Consulates will display the lists of registered voters abroad on the same days. According to the authorities, publication of the final, corrected roll is scheduled for 23 October 2026. Electoral documents will be sent to registered voters abroad in stages; voting at overseas polling stations is planned for 21 to 26 November 2026. Voters can check their details through the Statistics Office’s Sede Electrónica using the Cl@ve identification system.
The increase in the electoral roll is attributed mainly to two factors. First, demographic changes and internal migration are continually reflected in the register data. Second, there have been catch-up effects among Spaniards living abroad since the abolition of the so-called voto rogado in October 2022, which simplified registration and voting from abroad.
Two subsequent issues are relevant for administrative and legal purposes. First, the larger proportion of voters abroad increases the organisational burden on consulates and the Ministry of the Interior, particularly in the logistics of election documents and the counting of votes. Second, urgent proceedings over the registration of individual voters are under way in administrative courts. These include cases involving recently naturalised descendants of Spanish exiles, whose right to vote must be clarified before deadlines expire. The Public Prosecutor’s Office and the Abogacía del Estado refer in their statements to the practical limits of reviewing individual cases retrospectively immediately before election day.
The figures published now are preliminary. The register used for the vote on 29 November 2026 will be the corrected one, published by the Oficina del Censo Electoral in accordance with legal requirements after the objection period has ended.
