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 Mexico are: 

  • Two-factor authentication (2FA) or one-time passwords (OTP)
  • Promotional or marketing 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 Mexico, you should not obtain a Mexico Short Code.

Short codes require express consent from end users before any SMS can be sent; if you cannot obtain consent you should not use a short code.

Twilio and/or the carriers will not support certain types of campaigns, including: 

  • 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 sexual/adult content (which are prohibited by Twilio’s AUP).

Please note that if you order FTEU (Free to End User) Short Code the owner pays extra to send messages for which end users do not pay.

Minimum term commit for Mexico Short Code is 3 months.

The notice period before returning the Short Code is 1 month.
