Overview
- The National Electoral Chamber published the definitive voter roll, and citizens can verify their polling place, table and order at padron.gob.ar, via the Mi Argentina app, the 0800-999-7237 hotline, or the WhatsApp chatbot Vot‑A (+54 911 2455‑4444).
- For the first time nationwide, voters will use the Boleta Única de Papel: the poll worker signs and hands a single ballot and pen, the voter marks one option per category, folds it to show the signature, deposits it in the urn, and signs the register.
- Operational readiness is advancing with electoral materials delivered for distribution and public simulations such as the La Plata street drill, while in Santa Fe 70% of designated poll authorities have confirmed and first official trends are expected after 21:00 on election night.
- This midterm renews 127 seats in the Chamber of Deputies and 24 in the Senate, with senatorial contests in CABA, Chaco, Entre Ríos, Neuquén, Río Negro, Salta, Santiago del Estero and Tierra del Fuego.
- Santiago del Estero will hold concurrent provincial elections including governor, using the single-paper ballot for national races and traditional party ballots for provincial categories, with votes cast in separate urns.
