A2P registration

A2P 10DLC is the carrier approval process for business texting in the United States. If you want AgentStack to send real SMS follow-up from your business number, this step matters.

What you need first

• Your business legal name
• EIN or business tax information
• Website or landing page
• A public privacy policy and terms page
• The exact opt-in language you use on forms

What AgentStack helps with

AgentStack guides you through the registration flow, keeps the status visible, and stores the compliance details you already need for your lead forms and SMS consent.

Common delays

• Missing business information
• Weak or unclear opt-in wording
• A website that does not clearly show the business identity

Good rule of thumb

If a carrier reviewer can quickly see who you are, what texts you send, and how someone opts out, approval usually goes more smoothly.
