Anatel orders carriers to block abusive robocall lines for 15 days from 12 November under Provisional Measure 1.396/2026
From 12 November, Brazilian telecom carriers must block outbound calls for 15 days on lines showing abusive network use, under a determination by Anatel (Agência Nacional de Telecomunicações). The block applies to all numbers tied to the holder's CPF or CNPJ. The rule aims to curb high-volume automated calls that annoy consumers and can degrade network operation. It rests on Medida Provisória 1.396/2026, which covers authentication, identification and blocking of calls and messages on telecom networks.
Technical Details
- A block is triggered when a holder exceeds a daily limit and at least 85% of calls are short. Short calls are uncompleted, sent to voicemail, or last up to six seconds.
- The limits are more than 1,000 calls per access, per day and service, or more than 10,000 calls summed across all of the holder's accesses.
- The carrier has up to ten days to notify the holder and five more days to apply the block. The notice must state the call count, the share of short calls and the start and end dates.
- During the block the holder cannot place calls or activate new lines, but still receives calls. The carrier may charge the full service fee.
- Holders can request a review by form and commit not to repeat the practice. Requests may be refused if incomplete, not filed by the holder or legal representative, or if the holder reoffends.
- Exceptions apply to public bodies acting within their competences and to health, public security and civil defense providers.
Remediation
- Carriers must identify lines meeting the abuse criteria and meet the notification and blocking deadlines.
- Carriers must also offer a free online tool to look up the holder of certain numbers. For business lines it must show at least the corporate name and CNPJ, and it must not expose individuals' data.
- Organizations that run legitimate high-volume dialing should review their call patterns against these thresholds.
