The Brazilian business landscape is about to undergo a significant transformation. Starting in 2026, the traditional CNPJ, currently composed only of numbers, will give way to a new alphanumeric format combining letters and numbers.

This change, announced by the Federal Revenue Service, aims to meet the exponential growth in the number of businesses in the country and ensure the sustainability of the identification system for legal entities.

The depletion of the CNPJ

The accelerated growth of the Brazilian economy in recent years, driven by the formalization of individual micro-entrepreneurs (MEIs) and the emergence of new legal structures, has generated a growing demand for new CNPJ numbers.

The current numeric format, with a limited number of possible combinations, proved insufficient to meet this demand. The direct consequence was the imminent risk of depleting available numbers, which could paralyze the process of opening new businesses.

Every year, millions of new businesses are opened in Brazil, requiring the issuance of new CNPJs. This scenario, coupled with the increasing complexity of the tax system and the need to keep pace with market transformations, made the need for a more efficient and sustainable solution for identifying legal entities evident. 

Why is the CNPJ going to change?

The adoption of the alphanumeric format for the CNPJ is justified by the need to significantly expand the capacity to generate new registration numbers.

By combining letters and numbers, the system begins to offer a virtually unlimited number of combinations, ensuring the sustainability of business identification for many years to come. In addition, the alphanumeric format provides greater security and complexity, making it harder to generate fake CNPJs.

The growing formalization of businesses in Brazil, driven by programs like the MEI and the encouragement of entrepreneurship, requires an identification system capable of keeping pace with this growth.

The shift to the alphanumeric format anticipates this future demand, ensuring the availability of CNPJs for the coming decades and preventing disruptions in the processes of opening new businesses.

What will the new CNPJ format look like?

The new alphanumeric CNPJ will keep the same number of characters as the current format, but will include letters in its composition.

The structure will be similar to license plates, featuring a combination of letters and numbers. The check digits, used to validate the number, will also be adapted to the new format. This change ensures compatibility with existing systems and facilitates the transition.

Additionally, the combination of letters and numbers makes the CNPJ more secure, rendering forgery and the creation of fraudulent CNPJs more difficult. This increased security is essential to protect businesses and ensure the integrity of registration information.

What is the impact of the new alphanumeric CNPJ on businesses?

The transition to the alphanumeric CNPJ will bring a series of impacts for businesses, both in terms of adaptation and opportunities. Some of the main ones are:

Economic growth: Expanding the capacity to generate new CNPJs will stimulate the creation of new businesses, contributing to the country's economic growth. By eliminating the risk of running out of numbers, more entrepreneurs will be able to formalize their businesses, generating jobs and boosting the economy.

Expansion of Individual Micro-entrepreneurs (MEIs): The ease of obtaining a CNPJ will boost the formalization of micro-entrepreneurs, strengthening the informal sector and expanding the taxpayer base. This could generate an increase in tax revenue and contribute to the formalization of the economy.

New legal structures: The emergence of new forms of corporate organization, such as startups and social impact businesses, will be facilitated by the availability of new CNPJs. The flexibility of the alphanumeric format will allow the creation of specific CNPJs for each type of business, meeting the needs of an increasingly diverse market.

CNPJ as a unique identifier: The CNPJ will become the unique identifier for all legal entities, simplifying processes and integrating systems. This unification will facilitate the exchange of information between various government bodies and the private sector, streamlining processes and reducing costs.

Single registration for establishments: All establishments of a company, whether headquarters or branch, will have a single CNPJ, facilitating management and control. This measure will contribute to the modernization of tax administration and the fight against tax evasion.

Tax Reform: Standardizing the identification of legal entities, using a more robust and secure system, will facilitate the integration of various taxes and the creation of a simpler and more efficient tax system. With the alphanumeric CNPJ, it will be possible to simplify the calculation and payment of taxes, as well as fight tax evasion and avoidance.

Premises of the Alphanumeric CNPJ?

The implementation of the alphanumeric CNPJ was based on some fundamental premises:

Less impact on society: The transition will be carried out gradually and with minimal disruption to businesses and citizens. The Federal Revenue Service is committed to offering all the necessary support for businesses to adapt to the new rules.

Longevity of the solution: The capacity to generate a virtually unlimited number of CNPJs ensures the sustainability of the business identification system for many years. This means there will be no need for further changes to the CNPJ format in the near future.

Low implementation cost: The change is economically viable, with relatively low implementation costs. The Federal Revenue Service will seek to minimize financial impacts on companies by providing tools and resources to facilitate adaptation.

Continuity of the current numeric CNPJ: Existing CNPJs will remain valid, coexisting with the new alphanumeric CNPs. This ensures the continuity of business operations and avoids the need to re-register all taxpayers.

Reduced implementation time: The transition will be completed in a short period of time, minimizing disruption for businesses. The Federal Revenue Service will establish a detailed timeline for the implementation of the new format, ensuring that companies have sufficient time to adapt.

Clarity in identification: The new format will be simple and intuitive, making it easy for everyone to understand and use. The Federal Revenue Service will aim to provide informative materials and training to help businesses and citizens understand the new rules.

Incremental implementation: The change will be carried out gradually, allowing businesses to adapt to the new procedures. The Federal Revenue Service may establish transitional phases, allowing companies to test the new systems before adopting them permanently.

What are the next steps in rolling out the alphanumeric CNPJs?

The transition to the alphanumeric format of the CNPJ represents an important milestone in the modernization of Brazilian tax administration. However, implementing this change requires careful planning and the adoption of specific measures by companies and government bodies alike.

The Federal Revenue Service, responsible for managing the CNPJ, is working on a detailed schedule for implementing the new format. This schedule includes setting deadlines for system adaptations, releasing guidance for businesses, and conducting tests to ensure the efficiency of the new system. Additionally, the Federal Revenue Service is expected to provide tools and resources to assist businesses with the transition, such as manuals, tutorials, and support systems.

For companies, adapting to the new CNPJ format will require a series of actions. It is crucial for businesses to run a diagnostic on their computer systems to identify which ones need to be updated. It will also be necessary to invest in staff training so that employees can operate the new systems and ensure the correct use of the alphanumeric CNPJ.

Communication with clients, suppliers, and business partners is a fundamental step, so that everyone is aware of the change and can adapt to the new procedures.

The implementation of the alphanumeric CNPJ is a gradual process and requires the collaboration of everyone involved. Businesses, accountants, management systems, and government agencies must work together to ensure a smooth and efficient transition.

By adopting the new format, Brazil will be taking an important step towards modernizing its tax administration and simplifying processes for companies.
