FAQ
What is the alphanumeric CNPJ?
The alphanumeric CNPJ is the new identification format for legal entities in Brazil. It consists of 14 characters, mixing letters (A-Z) and numbers (0-9), while keeping the visual structure of the traditional CNPJ.
Why is the CNPJ changing to an alphanumeric format?
This change increases the number of possible combinations, avoids the exhaustion of the numeric format, modernizes the national registry, and improves system security and integration.
When will the new CNPJ be adopted?
The alphanumeric CNPJ will begin gradually starting in July 2026, initially for new registrations, such as new companies, branches, and rural producers.
What happens to existing CNPJs?
Current CNPJs will remain valid and can be used as usual. Systems must support both the old and new formats.

Several areas may be impacted, such as databases, validations, integrations, invoicing, APIs, registrations, reports, and tax compliance.
