'My whole identity was stolen': São Paulo residents speak out on the duplicate image crisis flooding Brazil's digital ID system

Cleide Aparecida Santos spent three months trying to convince a Poupatempo service centre that she exists. Her biometric photo had been flagged as a duplicate of another woman's record in the Cadastro de Pessoas Físicas system — a mismatch she says began after a 2024 document renewal at the unit on Avenida Paulista. Since then, she has been locked out of her Bolsa Família payments, her Caixa Econômica Federal account frozen pending manual review. She is one of a growing number of São Paulo residents caught inside a bureaucratic loop that neither the federal nor the municipal government has publicly claimed responsibility for fixing.

The problem of duplicate biometric images — photographs that are incorrectly linked to two or more CPF records — has intensified as Brazil accelerates its push toward a unified digital identity document, the new Carteira de Identidade Nacional, which began mandatory national rollout in January 2025. Digitisation at scale has exposed fault lines that paper systems concealed for decades: inconsistent photo standards across states, legacy data migrated without adequate deduplication checks, and a backlog of corrections that clerks at Poupatempo and Detran-SP units say they lack the tools to process quickly. The pressure is not abstract. For residents in Sapopemba, Brasilândia and other districts where formal employment paperwork depends on clean CPF records, a frozen status can mean losing a job offer within days.

What residents in the periphery are experiencing

The Movimento dos Sem-Documentos da Zona Leste, a community legal-aid collective based near the Tatuapé metro station, has been logging cases since February 2026. The group says it has catalogued more than 340 complaints from residents in the Zona Leste alone, with the highest concentration coming from Itaquera and São Mateus. The collective's intake forms — reviewed by this reporter — show that the most common consequence is suspension of single-register benefits including the Cartão do Idoso and Passe Livre Estudantil, the free student transit card administered by São Paulo's SPTrans agency.

One man in his sixties from the Penha neighbourhood described going to three separate Poupatempo branches — on Rua do Carmo, in Itaquera Shopping, and in Santo André — over a period of six weeks, only to be told at each that the correction request had to originate with the Secretaria da Segurança Pública do Estado, which in turn directed him back to the federal Receita Federal portal. The loop is not hypothetical. It is documented in the intake logs.

A woman from Brasilândia described a different but related problem: her daughter's school enrolment at a municipal EMEF in the Freguesia do Ó district was delayed because the child's birth registration photo had been duplicated against an unrelated adult record during a hospital digitisation drive in 2023. The family waited eleven weeks for the correction to propagate through the city's Secretaria Municipal de Educação systems.

The data gap and what pressure is building

Brazil's Tribunal Superior Eleitoral has previously acknowledged that biometric deduplication errors affected voter records in multiple states during the 2022 election cycle, though it did not release a national figure for São Paulo specifically. Separately, the Procon-SP consumer protection agency registered 1,247 formal complaints related to digital identity discrepancies between January and April 2026, a figure confirmed in the agency's publicly released quarterly report dated May 15, 2026. That number represents a 38 percent increase over the same period in 2025, according to the same document.

The federal government has not announced a dedicated correction window for São Paulo, but Receita Federal's online correction portal — accessed at gov.br — does allow CPF holders to upload supporting documents directly. Community legal workers at the Caritas Arquidiocesana de São Paulo, which operates a document regularisation service out of its office near Praça da Sé, recommend residents bring three forms of photo ID, a proof of address no older than 90 days, and a printed protocol number from any previous Poupatempo visit before attempting the digital correction. For residents without reliable internet access, the Praça da Sé Poupatempo branch offers in-person filing assistance on Tuesdays and Thursdays between 8 a.m. and 3 p.m. — though wait times in June have stretched past two hours. The correction, once submitted correctly, officially takes up to 30 business days to process.
