América MóvilBrazil's ANPD opened sanction process against América Móvil's Claro for sharing 100+ customer data points with Serasa without consent

Brazil's National Data Protection Authority (ANPD) announced on June 8, 2026 that it opened an administrative sanction process against Claro (América Móvil's Brazilian mobile, broadband, and pay-TV unit) for sharing more than 100 data points per customer -- including ZIP codes, complaint volumes, pay-per-view consumption, and mobile data usage -- with credit bureau Serasa Experian under a 2021-2023 partnership, without consulting affected customers. ANPD's Superintendent of Inspection said the sharing exceeded what was necessary and lacked transparency, and customers had difficulty reaching Claro's data protection officer. Claro said the data were used only for internal studies and not incorporated into market solutions, and that the partnership, authorized by antitrust regulator CADE, ended in 2023. The process could result in fines of up to R$50 million per violation or 2% of revenue under Brazil's LGPD.
