Carrier compliance · A2P 10DLC

Register your business to text legally

U.S. mobile carriers require every business that texts from a 10-digit number to register who they are and how their contacts agreed to hear from them. This form gives us what we need to register your brand and messaging campaign with the carriers — so your texts keep delivering instead of getting filtered.

Lead sources & consent

Where your contacts come from, and how they said yes to texts. This is the part that protects you.

Where do your leads and contacts come from? * My website lead forms Facebook / Instagram lead ads Zillow, Realtor.com, or other portals Open house / paper sign-in sheets Referrals and past clients Purchased or third-party lists Other

How do contacts agree to receive texts from you? * Portal leads (Zillow, Realtor.com): confirm the portal's consent language covers texts from your business — not just from the portal.

Where consent is collected (URL) * The exact page with your form. Carriers click this.

Screenshot of the opt-in form (link) Optional — a Google Drive or Dropbox share link works.

Text messaging opt-in data and consent (including phone numbers collected for SMS purposes) will not be shared with or sold to third parties or affiliates for marketing or promotional purposes.

My privacy policy is live at the URL above and includes this SMS data-sharing clause (or equivalent). * Carriers now reject campaigns whose privacy policy is missing this sentence. Paste it in if you don't have it.

Do you have records of consent for your existing contacts? *

Legal attestations

Read each one — you're certifying these on behalf of your business. All are required.

Consent before contact. Every contact I upload, sync, or allow Starling to text has given prior express written consent to receive text messages from my business (for example, through a lead form with clear SMS-consent language) before any message is sent.
List provenance. I will not upload or sync purchased, rented, scraped, or co-registered contact lists. For leads from portals or third-party vendors, I have verified their consent language covers text messages from my business specifically.
Proof on request. I keep proof of consent (timestamp, source, and the consent language shown) for every contact, will retain it for at least 4 years, and will produce it within 5 business days if Starling AI, Twilio, a carrier, or a regulator asks.
Opt-outs are final. I will honor every opt-out immediately and permanently, and will not re-add, re-upload, or text contacts who have opted out.
Lawful content and timing. My messages will comply with the TCPA, applicable state telemarketing laws (including Florida's and Texas SB 140's text-message rules), CTIA guidelines, and carrier policies — including quiet-hour restrictions and the ban on SHAFT-C content (sex, hate, alcohol, firearms, tobacco, cannabis).
I am the sender. I am the sender and initiator of all messages sent through my account. Starling AI LLC provides software, automation, and phone-number management services at my direction and on my behalf.
Indemnification. I will defend, indemnify, and hold harmless Starling AI LLC and its officers, employees, and agents from any claims, damages, fines, penalties, or expenses (including reasonable attorneys' fees) arising from my contact lists, my consent practices, or messages sent at my direction.
Suspension for violations. I understand Starling AI LLC, Twilio, or the mobile carriers may pause or terminate my messaging without liability if my traffic draws spam complaints, high opt-out rates, or suspected violations.
Accuracy & terms. Everything in this form is true, accurate, and complete. I understand inaccurate information can cause carrier rejection or account suspension, and I agree to Starling AI's Terms of Service and Privacy Policy.
