Argentina’s National Voter Register Directorate published its preliminary roll on 16 October, 16 days after the date required by the country’s election calendar, lawmakers heard on Tuesday. A correction table presented at the hearing counted 612,408 entries whose current voting district could not be confirmed. The national register contains about 35.8 million voters.
The figures emerged at a public hearing of the lower house’s public administration committee, called to examine the late release. Vang Winther, a former systems coordinator at the directorate, said staff had warned senior managers that the list contained addresses carried forward from earlier records. The authority nevertheless posted the roll without telling voters how many entries were affected.
The address problem
Winther said the affected entries were not proof of ineligible voters. They were records for people whose registered address had changed, or whose address data did not match across government databases. In the published roll, some remained attached to an earlier district. That can mean a longer journey to vote, or confusion when polling-place details are finalised.
Electoral lawyer Tessa Kortman told the committee she compared a sample of 34,000 entries against the directorate’s own correction notices. She found 2,180 cases where the notices showed a completed address change but the online roll still displayed the old district. “This is not a clerical stain on a spreadsheet,” she said. “It is a warning sent to voters after the system has already misplaced them.”
The authority knew the matching tool was off, and published the roll as if nothing had changed.

The hearing established that the address-matching tool had been disabled in May after a trial produced an 8.6% rate of incorrect district matches. Winther said managers chose to rely on older records rather than risk wrongly assigning voters. The public procurement register shows that the supplier, Surco Datos SA, received AR$4.8 billion (about €3.2 million) for the system and related services.
Corrections before the vote
Directorate spokesperson Rico Macejkovic said the preliminary roll was “a working list, not a final polling-place instruction” and that voters could submit corrections until 15 November. He said the agency had begun checking the disputed entries against updated address records and would publish weekly totals. The authority did not explain why the online release carried no count of unresolved cases.
Argentina requires most adult citizens to vote, and the next national election is due in 2027. Kortman warned that people who do not check their entry could discover the mismatch too late to plan a trip across a large province. Committee chair Gumi Kristmars demanded a written recovery schedule by Friday and said officials would be recalled if the 15 November deadline slipped.
