A2P 10DLC Campaign Approval Best Practices

On January 26, 2023, a new A2P 10DLC Campaign vetting process is going into effect. For details on the change, see this page. This change is relevant to customers using long code numbers to send messages to the United States under the A2P 10DLC framework. This change does not apply to Toll-Free messaging.


Effective January 26, 2023, newly registered A2P Campaigns are subject to a manual vetting process. To help ensure your Campaigns are approved in this vetting process, please follow these best practices when submitting new Campaigns.

Forbidden Use Cases Will Result in Campaign Rejection

Make sure your A2P Campaign does not involve prohibited content such as cannabis, hate speech, etc. and that your use case is compliant with Twilio’s Messaging Policy.

Ensure Data Accuracy and Consistency

Make sure you submit Campaign registrations with accurate and consistent data:

Ensure Your Use Case Involves Consumer Consent Before Sending Messages

Make sure you collect consumer consent appropriately. Please refer to the CTIA guidelines to see detailed instructions and best practices on handling consumer consent.

Please note that the ecosystem is constantly improving the vetting criteria as it comes across additional types of violations. Please do not consider the best practices listed above as a “catch-all” and guarantee an approval as long as you follow them all; instead, consider them as a baseline that illustrates the general direction of compliant, high-quality messaging that the ecosystem is moving towards.

Campaign Registration Recommendations

Campaign registrations should meet each of the following descriptions for each field.
