80105: Short Code Already In Service

This warning occurs when you try to add a short code that is already associated with the same Messaging Service sender pool. Use the ShortCodes subresource to manage short codes on a Messaging Service.

• You sent multiple requests to add the same short code to the Messaging Service.
• The short code was already added to the Messaging Service at an earlier time.
• Your application retried a previous add request after the short code was already associated with the Service.

• If the short code is already associated with the correct Messaging Service, no action is required.
• Check the Messaging Service sender pool before retrying the request. Review the Service in the Twilio Console or list the Service's short codes with the ShortCodes subresource.
• If you need to recreate the association, remove the existing short code from the Messaging Service and then add it again. Removing a short code from a Messaging Service does not cancel the short code from your account.
• Update your application logic to avoid duplicate create requests for the same short code.
