Overview

• The National Electoral Chamber published the definitive register, which can be checked via padron.gob.ar, Mi Argentina or the official Vot‑A WhatsApp chatbot (+54 9 11 2455‑4444) to obtain polling place, mesa and order number.
• Boleta Única de Papel debuts nationwide: the mesa authority signs and hands a single ballot and pen, the voter marks one option per category in the booth, folds as indicated, deposits it in the urn and signs the roll.
• The contest renews 127 national deputies and 24 senators in eight provinces, with voting open from 8:00 to 18:00 and standard DNI documents accepted for identification.
• Anyone not listed in the definitive roll cannot be added before Oct. 26 due to the May 13 cutoff, though formal claims can be filed for future corrections.
• Media outlets have circulated finalized candidate lists for key districts, including Buenos Aires province, Santa Fe and the City of Buenos Aires, to help voters identify their options on the new ballot.
