Short answer

Updated

Business SMS in Brazil is overseen by Anatel, with personal data governed by the LGPD and the ANPD. Sender requirements are set by the operators: alphanumeric where supported, or a numeric long code or short code. Marketing needs consent you can prove and a STOP or SAIR opt-out. OmniChannels.ai, powered by BroadNet, sends over direct routes to Vivo, Claro and TIM and adds WhatsApp, RCS, voice and fallback.

What you can send in Brazil with OmniChannels.ai

What to know before sending in Brazil

A practical summary, not legal advice. Anatel, ANPD and operator requirements change, so we confirm the current position for your traffic during onboarding.

ItemDetails
RegulatorsAnatel is the telecom regulator and the ANPD is the data protection authority. The operators enforce sender rules on their routes.
Sender IDSet by the operators: alphanumeric where supported, or a numeric long code or short code. Plan 5 to 10 business days, and longer for short codes.
ConsentUnder the LGPD the controller must be able to prove consent, and generic authorisations are void. Keep verifiable opt-in records for every number.
Opt-outOffer a one-step STOP or SAIR keyword, honoured across the operator, and suppress opted-out numbers across campaigns.
Sending hoursWe have not found a regulator-published time-of-day window for promotions. Agree hours with the operator and schedule for the recipient's local daytime.
WhatsAppUse approved templates for business-initiated messages. Meta charges per delivered message by category and market.

A good fit when

  • You write in Portuguese and want segment counts to stay predictable.
  • Your customers expect to reach you on WhatsApp.

Good to know before you start

Brazil business messaging questions

Is bulk SMS legal in Brazil?

Yes, provided you use a legitimate route, hold a lawful basis for the numbers (for marketing, in practice documented consent) and honour opt-outs. Rules come from Anatel, the operators, consumer law and the LGPD.

Do I need consent for promotional SMS in Brazil?

Treat it as required. The LGPD puts the burden of proving consent on the controller and voids generic authorisations. Keep the wording, timestamp, channel and number for every opt-in.

Can I use an alphanumeric sender ID in Brazil?

Alphanumeric senders are available where supported, with numeric long codes and short codes as alternatives. The operators set the requirements, so confirm which sender type each of Vivo, Claro and TIM accepts for your use case.

Do I need a short code in Brazil?

Not always. Short codes suit high-volume two-way programmes, while alphanumeric senders suit one-way brand messages. Our team confirms the options during onboarding, with a typical lead time of 5 to 10 business days.

Why does my Portuguese SMS cost two parts?

Characters such as ã, õ, á, ê and ô are not in the default GSM 7-bit alphabet, so one of them makes the message Unicode, which holds 70 characters per message and 67 per part. Check copy in a character counter first.

What are the penalties under the LGPD?

Administrative sanctions include warnings and a fine of up to 2% of the company's revenue in Brazil, capped at R$50 million per infraction, enforced by the ANPD. The fine is a ceiling, so take legal advice on your exposure.

Which Brazilian networks does OmniChannels.ai reach?

Vivo, Claro Brasil and TIM Brasil, all over direct routes. Test every campaign on all three networks.
