How to collect customer consent in A2P 10DLC campaigns



The objective of the article is to provide guidelines and best practices for collecting consumer consent appropriately, particularly in the context of messaging campaigns. It emphasizes the importance of adhering to CTIA guidelines and outlines specific procedures and examples to ensure compliance.

Best Practices for Obtaining Consent 

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

Best Practice Examples
Make sure consumer opt-in is collected appropriately If you indicate you collect opt-in via text messages, but your sample messages say “Hi, is this the owner of 123 Oak street? I’d like to discuss how I can help you sell your property”, it is clear that you have not collected appropriate consent before sending messages and your campaign will be rejected.
Make sure opt-in language is available on your website if you indicated in the "How do end-users consent to receive messages?" field that a consumer opts into your campaign on your company website If your brand Acme uses its website,, to collect phone numbers but your website Call-to-Action does not contain opt-in language such as “By providing your phone number, you agree to receive text messages from ACME. Message and data rates may apply. Message frequency varies.”, your campaign will be rejected.
We recommend having opt-out language in at least one of your sample messages For example, please consider adding language such as “Please reply STOP to opt out” in one of your sample messages

 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.
