Overview
- The definitive register is live at padron.gob.ar, where voters enter DNI, gender, district and a captcha to obtain their school, table and order number.
- Polling stations operate from 8:00 to 18:00 on Sunday, and locations can also be confirmed through the National Electoral Justice site or the MiArgentina app.
- Under the new single paper ballot, the table authority signs and issues one ballot and a pen; voters mark one choice per category, fold it, deposit it in the urn, and then sign the roll.
- Senate sections display candidate names with photos, while deputy lists show up to five names with photos of the first two, with ballot formats varying by whether a district elects senators.
- There are no primaries this cycle due to a 2024 reform; Buenos Aires renews 35 deputies, eight jurisdictions elect senators, and failure to vote can bring fines and temporary limits on public procedures.
