Without it, up to 70% of your business texts get blocked or labeled spam by AT&T, T-Mobile, and Verizon. Registration requires Brand + Campaign approval through The Campaign Registry. unLocked CRM automates the full registration at zero cost. ## Key data points - T-Mobile blocks approximately 100% of unregistered A2P SMS traffic; AT&T applies spam labels to roughly 70% of unregistered messages. - A2P 10DLC registration through The Campaign Registry typically costs $4-$50 for Brand registration, $40 for Brand Vetting, and $10-$15 per month per campaign — unless your CRM absorbs the cost. If you send any business SMS to US numbers — appointment reminders, AEP outreach, follow-up texts, two-factor codes — you must be registered for **A2P 10DLC**. Skip it and the major US carriers (AT&T, T-Mobile, Verizon) will block, throttle, or apply spam labels to most of your messages. ## What Is A2P 10DLC? **A2P 10DLC** stands for **Application-to-Person 10-Digit Long Code** messaging. It is the registration framework US wireless carriers built (administered by The Campaign Registry — TCR) to separate legitimate business SMS from spam. Three concepts to understand: - **A2P** — messages sent from an application or business (you) to a person (your client) - **10DLC** — a standard 10-digit US phone number (not a short code or toll-free) - **TCR** — The Campaign Registry, the central registry carriers use to vet brands and campaigns Without A2P 10DLC registration, US carriers treat your SMS as unregistered and apply heavy filtering: blocked messages, spam labels, throttled throughput, and surprise carrier fees. ## Who Needs A2P 10DLC? Any business sending SMS to US wireless numbers, including: - Insurance agents sending appointment reminders, quote follow-ups, AEP outreach - Agency owners running drip campaigns or birthday reminders - Any solo agent sending more than ~10 texts per day from a business line Personal texting from your iPhone to a friend? Not affected. Anything sent through a CRM, dialer, business SMS provider, or marketing automation platform? Required. ## A2P 10DLC Registration: 4 Steps ### Step 1 — Brand Registration Register your business as a **Brand** with TCR. You will need: - Legal business name and DBA (if applicable) - EIN (sole proprietors can use SSN) - Business address - Business website - Vertical (Insurance is a defined vertical) - Business contact email and phone Brand registration triggers a **Brand Vetting Score** (0-100). Higher scores unlock more daily message throughput. ### Step 2 — Campaign Registration Each use case requires a separate **Campaign**: - 2FA / OTP - Account notifications (appointment reminders) - Marketing (AEP campaigns, birthday SMS) - Customer care (general two-way conversations) For each campaign you submit: - Use case description - 3-5 sample messages - Opt-in language (how clients consent) - Opt-out language (STOP keyword handling) - Help language (HELP keyword handling) ### Step 3 — Number Assignment Once your campaign is approved, you assign one or more 10-digit phone numbers to it. A single brand can have multiple campaigns; a single campaign can have multiple numbers. ### Step 4 — Activation Carriers begin accepting your campaign-routed traffic at your assigned throughput tier. Throughput depends on: - Brand Vetting Score - Campaign type (2FA highest, marketing lowest) - Carrier (T-Mobile sets the toughest limits) ## A2P 10DLC Costs (Industry Standard) Most CRMs and SMS providers charge: - **Brand registration**: $4-$50 one-time - **Brand vetting**: $40 one-time (recommended) - **Campaign registration**: $10-$15/month per campaign - **Per-message carrier surcharge**: $0.001-$0.005 per SMS Some providers add their own setup fees on top — $50-$200. ## How unLocked CRM Handles A2P 10DLC (Free) unLocked CRM is one of the few insurance CRMs that **automates A2P 10DLC registration at zero cost** to the agent: - Brand registration handled in onboarding - Campaign registration submitted automatically based on the agent's selected use cases - No setup fees, no monthly campaign surcharge - Per-SMS cost: $0.0113 (carrier pass-through only) For more on the platform's compliance automation, see our [A2P registration walkthrough](/a2p-registration). ## Common A2P 10DLC Rejection Reasons Most rejections trace to one of: 1. **No clear opt-in** — your sample messages reference clients without showing how they consented 2. **Missing STOP/HELP language** — every campaign requires opt-out handling 3. **URL shorteners** — bit.ly, tinyurl, t.co are flagged as spam vectors 4. **Public free-email domain** — using gmail.com as your business email lowers your trust score 5. **Insurance vertical compliance** — extra scrutiny on lead-gen and AEP outreach campaigns ## What Happens If You Skip A2P 10DLC? - T-Mobile blocks ~100% of unregistered traffic - AT&T applies spam labels to ~70% of messages - Verizon throttles delivery and applies fees - Your sender reputation degrades — recovery takes weeks The cost of registering ($0 with unLocked CRM, $50-$200 elsewhere) is trivial compared to losing 70% of your AEP outreach. ## FAQ ### undefined ### undefined ### undefined ### undefined ### undefined ## Related - https://unlockedcrm.ai/blog/register-business-phone-number-avoid-spam - https://unlockedcrm.ai/blog/block-spam-calls-insurance-agents - https://unlockedcrm.ai/blog/scope-of-appointment-explained --- Source: [A2P 10DLC Compliance Walkthrough: Complete 2026 Registration Guide for Insurance Agents](https://unlockedcrm.ai/blog/a2p-10dlc-compliance-walkthrough) — unLocked CRM, the AI CRM built for insurance agents.
