Overview
- On Sunday, October 26, voters will renew 127 national deputies and 24 senators, with Senate seats chosen in eight jurisdictions: CABA, Chaco, Entre Ríos, Neuquén, Río Negro, Salta, Santiago del Estero and Tierra del Fuego.
- The Cámara Nacional Electoral has released the definitive voter roll at padron.gob.ar; citizens must enter DNI, gender, district and a verification code to obtain their polling place, mesa and order number.
- For 2025 there are no PASO primaries after a 2024 reform, making this a single decisive national vote; Buenos Aires province elects 35 deputies and no senators, with winners taking office on December 10, 2025.
- The Boleta Única de Papel consolidates all parties on one sheet with parties in vertical columns and offices in horizontal rows, replaces the cuarto oscuro with voting booths and aims to speed counting and avoid missing ballots.
- Voting steps: present DNI, receive a signed official ballot and pen, mark one choice per category in the booth, fold to show the authority’s signature, place it in the ballot box and sign the register; valid, blank, null and impugned vote types are applied under CNE rules.
