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 Ireland 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 Ireland, you should not obtain an Irish 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 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 sexual/adult content (which are prohibited by Twilio’s AUP).

Minimum term commit for the Short Code is 12 months.

The notice period for returning the Short Code is 3 months (provided minimum term commit has been fulfilled).

If the Short Code does not receive any traffic in Ireland for extended amount of time, the Short Code might get disconnected due to absence of usage without any prior warning.

Refer to this article for detailed explanation on Ireland Short Code Best Practices.
