When sending a direct message from Engagement, you may sometimes receive send failure codes from numbers that are triggering an error. These errors are commonly related to sending text messages to phone numbers that have been entered incorrectly or cannot receive text messages. Learn more about each error code and how to resolve below.

Error Codes

"Carrier rejected as invalid destination address"

This could mean the number is not in the numbering plan (area code does not exist or the number is just invalid), or the number is not enabled for messaging (such as a landline). Additionally, for toll free messages to T-Mobile, this could also mean the user has opted to block all toll free and short code traffic.

"Invalid Application ID"

If you are using your ALT SMS number to send a direct message and receive this error, please submit a new port request. If you are using your MAIN SMS number to send a direct message and receive this error, please contact Dental Intelligence Customer Support.

"TFN Not Verified"

If you receive this error message, please contact Dental Intelligence Customer Support.

"Rejected as Spam (Future)"

If you receive this error message, it is because the phone number entered as the recipient of your message has been flagged as spam. Please contact Dental Intelligence Customer Support.

"Unallocated to Number"

If you receive this error message, it is because the phone number entered as the recipient of your message does not exist or has been entered incorrectly. Please check with your patient to ensure that the phone number they have provided you with is correct and try sending again.

"Unallocated from Number"

If you receive this error message, please contact Dental Intelligence Customer Support.

"Invalid Service Type"

If you receive this error message, it is because the delivering phone number does not allow text messages (ie, landline, or receiving number has not paid their bill). Please check with your patient to ensure that the phone number they have provided you with is able to receive text messages and try sending again.

If a patient's text messaging service has been restricted, you won't be able to send them messages. To discover how to unblock them, please click here.
