The CPF number (Cadastro de Pessoas Físicas, [sepeˈɛfi]; Portuguese for "Natural Persons Register") is the Brazilian individual taxpayer registry, since its creation in 1965.[1] This number is attributed by the Brazilian Federal Revenue to Brazilians and resident aliens who, directly or indirectly, pay taxes in Brazil. It's an 11-digit number in the format 000.000.000-00, where the last 2 numbers are check digits, generated through an arithmetic operation on the first nine digits.[2]

In May 2020, a digital version of the document was promoted for Android and iOS.[3]

In June 2020, an audit from the Tribunal de Contas da União (Federal Court of Accounts, often referred to as TCU) revealed that there were at least 12.5 million CPFs more than the total population.[4]

During COVID-19 pandemic the Revenue reported 223.8 million active CPFs, the problem is that, according to the Brazilian Institute of Geography and Statistics (IBGE), the Brazilian population at the time of the survey was around 211.4 million people, updated to 211.8 million at the end of August.

Auditors revealed that there was evidence that an individual was already dead in 3.3 million valid entries and more than 78.000 active CPFs of people over 110 years old. International surveys show that there are only 29 people in this age group in the world – and only one lives in Brazil.[5]

During the COVID-19 pandemic, all requests for CPF from new foreign residents are being taken virtually.[6][2]

Foreign residents can request a CPF online or at an embassy or consulate, when available. The online form is available in Spanish and English. Foreign residents can also check the nearest diplomatic mission representation abroad and its working hours: [1], [2], [3], [4]

In November 2021, Santa Catarina launched a unified document, with CPF and RG (Identity Card) integrating a single 11-digit number, authorities say the initiative will reduce fraud, but the change is not mandatory.[7]

As a general-purpose identification number[edit]

On 11 January 2023, a federal law has been enacted in Brazil to consider the CPF number "unique and sufficient" to identify citizens on government databases.[9] The law also requires the CPF number to appear on databases and documents of government entities, the civil registry of natural persons and professional councils, especially the following documents:

  • birth, marriage and death certificates;
  • National Identity Document (Documento Nacional de Identidade or DNI);
  • Worker Identification Number (Número de Identificação do Trabalhador or NIT);
  • registration with the Social Integration Program (Programa de Integração Social or PIS) or the Public Servant Patrimony Formation Program (Programa de Formação de Patrimônio do Servidor Público or PASEP)
  • National Health Card (Cartão Nacional de Saúde);
  • voter registration;
  • work cards;
  • driver's license numbers;
  • military certificates;
  • professional identity cards issued by fiscalization councils of regulated professions, and;
  • other registration certificates and registration numbers on government databases.

The law also specifies that all new identity documents issued or re-issued by government entities or professional councils must use the CPF number as the identification number. The law is effective as soon as it is published, and government entities have 12 months from the publication of the law to adopt the CPF number as the identification number on their systems and procedures, and 24 months for entities to accomplish interoperability between databases through the CPF number.
