According to an October 14, 2026 report on the official website of the Brazilian Chamber of Deputies, Brazil has issued Provisional Decree No. 1396/26, aimed at combating telecom fraud, nuisance calls, and spam messages. The decree, overseen by the National Telecommunications Agency (Anatel), took effect upon publication but must be approved by both the Chamber of Deputies and the Federal Senate within 120 days to be formally converted into law.
The decree establishes a national central numbering database regulated by Anatel for caller identity verification. Call authentication consists of three steps: the originating carrier completes call authentication, the transit carrier preserves the authentication information, and the terminating carrier verifies the authentication status before connecting the call to the user. In principle, carriers must block calls that fail authentication (Anatel may define exceptions), as well as calls and SMS initiated using non-compliant access codes. For authenticated enterprise calls, mobile devices must display the company name and logo.
The decree defines the criteria for determining misuse of telecommunications services: within a single day, a single number makes more than 1,000 outgoing calls, or all numbers registered under the same entity collectively make more than 10,000 outgoing calls, and at least 85% of such calls are short calls (unanswered, diverted to voicemail, or with a call duration of 6 seconds or less). Meeting both conditions constitutes misuse. Carriers may impose a 15-day outgoing-call suspension on non-compliant accounts. Calls from government agencies, public health, public safety, and civil defense authorities are excluded from these misuse criteria, with supporting implementing rules to be subsequently issued by Anatel.
