In plain English
It’s the permission slip US carriers require before your business can text customers.
Together: the US system that legally authorizes businesses to text customers from a registered local phone number.
What is A2P 10DLC?
Before 2021, any business could send texts to customers from any US phone number. The result was a flood of spam that eroded trust in SMS as a communication channel. American consumers started ignoring texts from numbers they didn’t recognize.
The major US carriers (AT&T, Verizon, and T-Mobile) responded by creating A2P 10DLC. Starting in 2021 and fully enforced by 2023, any business sending SMS at scale must register with The Campaign Registry (TCR), a neutral third party that vets businesses and their messaging use cases.
The registry stores your business information and the types of messages you plan to send. The carriers query the registry when your messages pass through their networks. Registered messages get delivered. Unregistered messages get filtered, throttled, or blocked outright, and the sender never gets a notification that it happened.
“Unregistered business SMS is silently filtered. The motel thinks the text sent. The guest never received it.”
Why it matters for your motel
Guest communication at independent motels runs almost entirely through SMS. A guest texts about check-in times, WiFi passwords, late arrivals, and maintenance issues, all from the same channel. When that channel fails silently, the guest thinks your motel is ignoring them.
Without A2P registration
- ✕Messages are silently filtered as spam by AT&T, Verizon, and T-Mobile
- ✕Guests never receive responses, but you never know the delivery failed
- ✕Carriers can block your number entirely after repeated violations
- ✕Fines of $500–$10,000 per incident for unregistered commercial SMS
- ✕Your motel earns a 1-star review for not responding, when you did
With A2P registration
- ✓Messages arrive reliably across all major US carriers
- ✓Guests trust the texts. Registered senders get higher open rates
- ✓Your number is protected from carrier blacklisting
- ✓Full legal compliance with TCPA and carrier requirements
- ✓Guest conversations build the property's reputation instead of harming it
How registration actually works
If you were to register directly, here is the process. It is not designed for independent motel owners. It is designed for enterprise compliance teams. Most operators have never heard of The Campaign Registry. They don’t know what a “use case category” means, and they have no idea that vague language in their message samples (something like “we will send guests helpful information”) gets the application rejected and restarts the clock. The form asks questions that assume you have a legal team. You probably already spend $2,500 or more per month on overnight labor just to keep someone available to answer these same guest questions. A2P registration is one more thing stacked on top.
Register your business with The Campaign Registry
Submit legal business name, EIN, address, business type, and website. TCR verifies against public records. Takes 1–3 business days for approval.
Define your messaging campaign
Describe exactly what types of messages you will send: customer service, notifications, promotions. Each use case is evaluated separately. Vague descriptions get rejected.
Register your phone number
Link your specific 10-digit number to your approved campaign. Each carrier (AT&T, Verizon, T-Mobile) processes the registration independently. Processing takes 2–5 business days per carrier.
Pay the ongoing fees
TCR charges a one-time brand registration fee plus a monthly campaign fee. Each carrier charges a separate per-number monthly fee. Total ongoing cost runs $10–$30/month in registration fees alone.
Maintain TCPA compliance
Keep written records of guest opt-in consent. Honor STOP requests within 24 hours. Include required disclosures on all commercial messages. Violations can trigger $500–$1,500 in statutory damages per message.
The total setup process takes 2–5 business days if everything is submitted correctly. Incomplete applications, incorrect business details, or vague use case descriptions can extend this to 2–3 weeks. And that is before you build the actual messaging system.
How Suzy handles this for you
Suzy AI is fully A2P 10DLC registered. Our Twilio number (+1 682 757 1974) carries an approved 10DLC campaign across AT&T, Verizon, and T-Mobile. The registration covers hospitality customer service messaging: exactly the WiFi, check-in, parking, and maintenance questions your guests text about.
When you use Suzy, you inherit our compliance. You do not register separately. You do not manage fees. You do not navigate TCR applications or carrier review timelines. Your guests text the Suzy number, and their messages arrive, registered, compliant, and delivered. It is why AAHOA members evaluating hotel technology consistently flag A2P compliance as one of the first questions to ask any guest messaging platform.
A2P compliance is also directly tied to the labor savings case. When you understand what overnight coverage actually costs, registered SMS becomes an obvious part of the ROI math.
We also handle TCPA compliance automatically. When a guest texts STOP, Suzy adds them to your property’s opt-out list within seconds and never messages them again. No manual tracking required from you. All opt-in consent is recorded in your message logs.
What Suzy handles for you
Every day you send guest texts without A2P 10DLC registration is a day your messages might not arrive. The guest assumes you ignored them. The review suffers. You find out weeks later, if at all. Suzy ships with A2P 10DLC handled. You do not register. You do not wait. You just send texts that arrive.
