Use Cases

Short codes are ideal for high-throughput programmatic messaging.

Short codes are approved for specific use cases, so if you are experiencing carrier filtering on long codes, you may be a good candidate for short codes.

Some of the most common use cases for short codes in Brazil are: 

  • Two-factor authentication (2FA) or one-time passwords (OTP).
  • Promotional alerts.
  • Account alert notifications.
  • Reminders (appointments, upcoming payments, etc.).


Short codes can only message users on carriers within the countries in which they are provisioned. Although Twilio can provision short codes in multiple countries, if your customers are not located in Brazil, you should not obtain a short code in Brazil.

Short codes require express consent from end-users before any SMS can be sent. Unless you obtain consent, you shall not use a short code. Twilio and the carriers will not support certain types of campaigns, including but not limited to:

  • Those in which express end-user consent cannot be obtained. This includes friend-to-friend invite-based campaigns, as well as opt-ins obtained through lead generation.
  • Campaigns containing unsupported content, which are prohibited by Twilio’s AUP.

The notice period for returning your short code is 35 days.

If a short code does not receive any traffic in Brazil for extended amount of time, it may get disconnected due to absence of usage without any prior warning.


Traffic restrictions

  1. Time: Promotional messages can only be sent between 9am - 10pm. User agreement is required, in case messages are to be received outside these hours. 
  2. Frequency: Seven Promotional messages per week maximum. User agreement is required, in case the promotional messages are to be sent more frequently than the limit set. 
  3. Traffic: Promotional and Transactional traffic can not run on the same short code. Promotional (marketing-related messages) and Transactional (OTP/TFA) messages require separate short codes. Not meeting this requirement will result in your short code being withdrawn without prior notice.

Kindly refer to Brazil Short Code Best Practices for further details about the short codes’ restrictions, requirements and best practices in Brazil.

Other Options

Only standard (random number) short codes are available in Brazil. Please note, that all short codes in Brazil are Free To End User (FTEU). 

Specific short code number availability can be checked upon request, otherwise you will be automatically assigned a random number.

Brazil short codes are five digits long. Other format requests are handled on a case-by-case basis and are subject to availability.
