Brazil represents one of the largest fax markets in Latin America, with continued usage across government, legal, healthcare, and financial sectors. While the country has embraced digital communication rapidly in recent years, fax remains embedded in institutional workflows where formal documentation, regulatory compliance, and verifiable delivery are required -- particularly in interactions with public agencies and the judicial system.
Government administration is a key driver. Federal ministries, state secretariats, prefeituras (municipal offices), cartórios (registry offices), and the Receita Federal (Federal Revenue Service) maintain active fax lines for receiving official documents, applications, and correspondence. Brazil's administrative structure -- with 26 states, one federal district, and thousands of municipalities -- means fax infrastructure is widespread but varies significantly between urban centres and smaller cities. While the government's digital transformation programme and platforms like Gov.br have expanded online access to public services, many offices continue to accept fax for official submissions, especially for processes that require signed or stamped originals.
The legal and judicial sector reinforces fax's role. Advogados (lawyers), cartórios (notary and registry offices), tribunais (courts), and the Ministério Público (public prosecution service) use fax for petições (petitions), legal notices, contracts, and official correspondence. While Brazil's electronic judicial systems -- such as PJe (Processo Judicial Eletrônico) -- have modernised court filings considerably, fax remains a fallback channel, particularly in smaller jurisdictions and for communication with parties not fully integrated into electronic platforms.
Healthcare contributes to sustained usage as well. Hospitals, clínicas, laboratórios, and pharmacies use fax for patient records, referrals, prescriptions, and insurance documentation. Brazil's Lei Geral de Proteção de Dados (LGPD) imposes requirements on the handling of personal data including health information, and fax provides a familiar channel with built-in delivery confirmation.
Financial institutions -- banks, insurance companies, and corretoras (brokerages) -- round out the picture, using fax for account documents, claims, and compliance-related correspondence.
For anyone sending a fax to Brazil, the country code is +55, and the leading zero of the area code must be dropped when dialling internationally. For example, a São Paulo number beginning with 011 becomes +55 11 followed by the local number. For detailed formatting instructions, see our guide on how to send an international fax online.
