Can Twilio numbers receive SMS from a short code?

By default, Twilio long code numbers cannot receive messages from short code numbers.

Upon request, Twilio can enable your account(s) to receive incoming messages from short codes. This will allow long code phone numbers on your account to receive messages from short codes.

In order to request this feature be enabled on your account, please submit a Support ticket and refer to this FAQ article.

Before you request for your account to be enabled to receive incoming short code SMS, please note the following important limitations:

  • The setting is applied to your Twilio Account SID, and will affect all of the long code (local, national or mobile) SMS-capable numbers that belong to the Account SID you have requested.
  • Short codes and Toll-Free numbers cannot receive SMS from short codes, and will not be affected by this setting.
  • By design, a short code number can only send messages to long code numbers from the same country as that short code. In order to receive messages, you must use a Twilio number from the same country as the short code. For example, if you are trying to receive messages from a Canada short code, you will need to use a Canada Twilio number.
  • Twilio cannot guarantee that every short code globally will be able to reach Twilio numbers, even if the Twilio number is from the same country as the short code. There may be  cases where an external short code carrier does not have reach to Twilio, or some other technical issue prevents those messages from reaching our platform.
  • Some companies may choose only to send OTP codes to mobile numbers. This is common in larger companies including OTP from Apple, Microsoft, Google, Facebook, and WhatsApp.
  • You will NOT be able to send outbound messages to these short codes. Therefore, you will not be able to reply, opt out via "STOP," or send "HELP" messages. Before enabling this setting, our Support team will send you a disclaimer from our Legal team and ask you to confirm that you understand and accept this particular limitation.
