Overview of A2P Registration
A2P 10DLC registration is a mandatory carrier requirement for businesses sending application-to-person (A2P) SMS traffic in the United States. Registration is enforced by U.S. cellular carriers to verify sender legitimacy, consent integrity, and message transparency. Follow the guidelines in this article to get approved and stay approved.
Scenario 1: Mandatory Phone Number Collection
When a phone number field is mandatory (marked as required) in form, survey, quiz, web chat widget or calendar booking, users cannot be forced to agree to SMS messaging in order to submit. The phone field and consent choices are separate decisions.
When a phone number field is mandatory, apply the rules below:
Strict Seperation
Consent checkboxes must be distinct for Marketing messages vs. Non-Marketing messages so subscribers can opt into one, both, or neither. Make sure you have two checkboxes with the following exact messages:
"I consent to receive marketing text messages from [Business Name] at the phone number provided. Frequency may vary. Message & data rates may apply. Text HELP for assistance, reply STOP to opt out."
I consent to receive non-marketing text messages from [BUSINESS NAME] about [USECASEFROMCAMPAIGNDESCRIPTION] Message & data rates may apply. Text HELP for assistance, reply STOP to opt out.
[BUSINESS NAME]should match what’s on the CP 575/147C Document.
No Pre-Selection of Checkboxes
Consent checkboxes cannot be pre-selected by default. The users must manually select the consent checkboxes that they would like to agree to.
Consent Checkboxes are Always Optional
Even if the phone number is required, checking the consent box must remain optional for submission.Submitting a form (even with a phone number) cannot be conditional on marketing consent.
After submission, you must execute the communication channels based on their consent checkbox selections only.
