Single Registration

Among the government programs that attract the most attention, the Single Registry is perhaps the one that appears most on the agenda. It became more popular with the arrival of the Coronavirus pandemic, as it was one of the requirements for receiving Emergency Aid.

Also known as CadÚnico, it often appears on the list of prerequisites for Brazilians to have access to the benefits that are offered by the government. In this context, understanding what the Single Registry is is fundamental.

What is the Single Registry?

The Cadastro Único was created in 2001, during the government of Fernando Henrique Cardoso. It was established by Decree No. 3,887 and is still one of the most important government records today.

Its main intention is to map the number of families living in a state of poverty or extreme poverty in Brazil.

For this purpose, relevant information about the family nucleus is collected. The surveys serve as a basis for the creation of registers that point out information about these people.

In addition to the essential information about each member, data are collected regarding the means of transport and situations of the residence. In this way, the vulnerability of family members is also mapped.

Who can apply?

As stated earlier, the main function of the cadastre is to identify families that live in a situation of vulnerability due to states of poverty or extreme poverty. Data are collected by each municipality.

To be part of the Single Registry, therefore, it is necessary to comply with some basic prerequisites. Therefore, you can apply:

  • Families with monthly income of up to half a minimum wage per capita. In 2021 this is equivalent to 550 reais per family member.
  • Families with monthly income of up to 3 minimum wages. In 2021 this is equivalent to 3,300.
  • Families with an income above R $ 3,300, but who participate in government social projects.
  • Homeless people.
  • One-person families (people who live alone).

It is important to note here that all conditions must be proven. The Cadastro Único makes a very careful analysis to ensure that only the group that should be contemplated has access to the program.

How to register

There are different ways to make the Cadastro Único. One of the most frequent is through home visits by qualified professionals who accompany families in a state of vulnerability.

Generally, these visits – carried out by social workers – already include strategies to monitor and ensure the well-being of these people. The Single Registry is one of those means of care.

However, if you meet the conditions mentioned above or if you have a family member who does, you can register on your own. In this case the step by step is as follows:

  • Look for the Reference Center for Social Assistance (Cras) in your municipality;
  • Communicate the need to perform the Single Registry;
  • Answer all questions asked by the attendant;

It is important to highlight that the registration can be done by family members who live in the same house and who are over 16 years old.


In order for the Single Registry to be carried out, it is necessary to present a document of each member of the family. See below which documents are accepted in the registration:

  • Birth certificate;
  • Wedding certificate;
  • CPF;
  • Identity card (RG);
  • Administrative indigenous birth certificate (RANI);
  • Work card;
  • Voter title.
  • Proof of residence.
