Street blocks aiming to participate in the Carnival festivities in Belém are required to obtain a prior license from the city government. This process must be handled completely online and is the responsibility of the event organizers, who must liaise with the Municipal Secretary of Culture (Semcult). According to local regulations, the license must be requested at least 10 to 15 days before the event is scheduled to take place, ensuring that all necessary planning and safety measures are adhered to.

To request the license, organizers need to access the Descomplica platform, where they will fill out their personal information and select the option for "Licensing of Events in Public Spaces." The application requires answering mandatory questions regarding contact details, the address, and email of the responsible party. Additionally, they must attach a project detailing the route and structure of the planned block, including items such as stages and sound systems, allowing city officials to evaluate the feasibility and safety of the event.

The local government highlights that this licensing requirement aims to ensure that Carnival programming is conducted safely and in compliance with regulatory standards. By formalizing the process, the city also seeks to promote a well-organized Carnival, helping to mitigate risks associated with large public gatherings, and ensuring the enjoyment of both participants and spectators during this vibrant cultural celebration.
