Voice Call Compliance in Brazil

Key Rules for Voice Calls in Brazil

Under Anatel rules, telemarketing calls in Brazil must use the 0303 prefix, and consumers can join the 'Não Me Perturbe' list to block telemarketing from telecom companies and banks.

Automated and prerecorded calls are tightly regulated in the US (TCPA and the National Do Not Call Registry) and Canada (CRTC Unsolicited Telecommunications Rules), and other countries in the region have their own registers and rules.

Practical Checklist

• Check whether the call is promotional or a service call, as the rules differ.
• Use permitted calling numbers and caller ID, and never hide or spoof the calling number.
• Screen numbers against any national do-not-call register before promotional campaigns.
• Call only within permitted hours in the recipient's time zone and keep recorded messages short.
• Offer an easy way to stop further calls and record call consent where required.

Contact data

Format numbers in international E.164 format with the +55 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.

Digital Habits and Channels in Brazil

Brazil is one of WhatsApp's largest markets, and businesses use it for sales, support and order updates as a matter of course; Instagram and TikTok drive discovery. SMS is used for codes and reminders, and consumers can register on Não Me Perturbe to block telemarketing calls from telecom and bank-loan providers.

Pix, the central bank's instant payment system, is used by most adults, and boleto bancário and card instalments (parcelado) remain important. Black Friday, Christmas, Mother's Day, Carnival and the 13th salary paid at year-end shape spending, and the LGPD governs consent.

Brazil is Latin America's largest economy, with agribusiness (soybeans, coffee, sugar, beef and orange juice), mining, oil from the offshore pre-salt fields, and large manufacturing, banking and retail sectors. Pix, the central bank's instant payment system launched in 2020, is used by most adults and has overtaken cards for many purchases, while boleto bills and instalment card payments (parcelamento) remain common. The LGPD requires a legal basis for marketing, and the ANPD supervises it. Consumers can block telemarketing calls through the 'Não Me Perturbe' register, and the Black Friday, Mother's Day and Christmas periods drive the biggest campaigns.

Advertising Alongside Messaging

Advertising should follow the CONAR self-regulatory code and the Consumer Defence Code, including CONAR's guide on influencer advertising.
