Interpreting Texting Error Codes
Updated over 2 months ago

Virtually all text messaging actions (whether Peer-to-Peer, Broadcast, or Automated) will encounter some level of errors in sending. Ideally, these errors are relatively minimal. But sometimes your action may encounter a higher-than-usual level of erroring. Regardless, it's important to be able to assess the deliverability of your texting campaigns and specific breakdowns of what caused errors.

How to Find Error Codes

The easiest way to find which error codes impacted your texting action is by navigating to the View Results page of the action. At the top of that page, you'll see a summary of Error Details, listing the number and proportion of messages that encountered each of the three types of errors: Impactive Safeguards, Twilio Errors, and Carrier Filtering.

For further details on the exact error codes within each of those types, you can either click on the error summary numbers, or scroll down the View Results page and click on the Errors tab. This tab displays the full table of all error codes relevant for this texting action.

In addition to these breakdowns, you can export full error information in a CSV if desired. Click Export Messages at the bottom of a particular action's View Results page, or head to Data > Exports > + New Export > Messages to generate a fuller export of messages from across multiple actions. Either way, these exports will include an 'error_code' column, with a code listed (if relevant) for each individual message.

Glossary of Error Types and Codes

There are three types, or categories, of error codes that may occur during your texting action:

Impactive Safeguards

These messages are filtered out by Impactive before they even reach Twilio/carriers, to save you money by not attempting to send messages that Impactive knows won't go through. These errors often have to do with messages being sent to a certain contact too frequently, an undeliverable landline number, etc. Read more about Impactive's 10DLC safeguards here.

Twilio Errors

These errors occur when Twilio (Impactive's underlying messaging provider) attempts to send messages and has an issue. These errors often have to do with invalid phone numbers. The most common Twilio errors are listed below, but you can also find a full glossary of errors here, directly from Twilio's support documentation (use Control-F to find a specific error).

Carrier Filtering

These errors occur when both Impactive and Twilio have passed your messages through, but carriers (AT&T, Verizon, etc.) prohibit them from reaching the recipient. This is error code 30007, explained in more detail by Twilio here; essentially, carriers will filter messages if they suspect them of being spam or fraud. Adhering to script best practices can minimize this error type.
