SMS Compliance for Real Estate: TCPA, DNC & 10DLC Explained

If you're a real estate professional using text messaging to communicate with leads and clients — and you should be — compliance isn't optional. It's the law. And the penalties for getting it wrong are severe: up to $1,500 per message sent in violation of the Telephone Consumer Protection Act (TCPA).

The good news? Compliance isn't complicated once you understand the rules. This guide breaks down everything real estate professionals need to know about TCPA, DNC lists, 10DLC registration, and best practices for staying compliant in 2026.

Understanding the TCPA

The Telephone Consumer Protection Act (TCPA) is the primary federal law governing text message marketing and automated communications. Here's what it requires:

Express Written Consent

Before you send any marketing or promotional text message, you need express written consent from the recipient. This means they've actively opted in to receive texts from you — not just given you their phone number.

For real estate, consent typically comes from:

• Online lead forms with clear SMS opt-in language and a checkbox
• Open house digital sign-in sheets with texting consent
• Website contact forms that include texting authorization
• Verbal consent documented in writing
• Text-to-join keyword campaigns (e.g., "Text HOME to 55555")

What Counts as Consent

Important: having someone's phone number is NOT consent. Buying a list of phone numbers is NOT consent. Someone giving you their card at a networking event is NOT consent to send marketing texts. You need an explicit, documented opt-in specifically for text messaging.

Opt-Out Requirements

Every text message campaign must include a way for recipients to opt out. The industry standard is including "Reply STOP to unsubscribe" in your messages. When someone opts out, you must honor that request immediately — no exceptions, no "are you sure?" messages.

The Do Not Call (DNC) Registry

The National Do Not Call Registry is a list of phone numbers belonging to consumers who have requested not to receive telemarketing calls and texts. As a real estate professional, you must:

• Scrub your contact lists against the DNC registry before any campaign
• Update your DNC check at least every 31 days
• Maintain your own internal DNC list of anyone who has asked to be removed
• Never contact a number on either the national or your internal DNC list

Note: There are exceptions for established business relationships. If someone has purchased a home through you in the last 18 months, you may be able to contact them even if they're on the DNC list. However, this exemption is narrow, and it's always safer to have explicit consent.

10DLC Registration: The New Standard

10DLC (10-Digit Long Code) is the new standard for business text messaging. As of 2024, all businesses sending SMS through standard 10-digit phone numbers must register with The Campaign Registry (TCR). Here's what you need to know:

What is 10DLC?

10DLC is a system that allows businesses to send A2P (Application-to-Person) text messages through standard local phone numbers. It was created to reduce spam, improve deliverability, and give mobile carriers visibility into who is sending messages and why.

Registration Requirements

To send SMS as a real estate business, you need to:

• Register your brand: Your company information, EIN, website, and business details
• Register your campaign: The specific type of messages you'll send (e.g., "Real estate lead follow-up," "Open house notifications," "Market updates")
• Get approved: Carriers review your registration and assign a trust score that determines your messaging throughput

Why It Matters

Unregistered numbers face severe deliverability issues. Carriers like T-Mobile, AT&T, and Verizon actively filter unregistered traffic, meaning your messages may never reach your leads. Registration ensures your messages get delivered reliably.

Best Practices for Real Estate SMS Compliance

• Always get consent first. No exceptions. Build opt-in into every lead capture form, open house sign-in, and website form.
• Include opt-out in every message. "Reply STOP to opt out" should appear in your first message to any new contact and periodically thereafter.
• Keep records. Document when and how each contact opted in. If challenged, you'll need proof of consent.
• Scrub against DNC regularly. Monthly scrubbing is the minimum; weekly is better.
• Register for 10DLC. This is non-negotiable in 2026. Work with your messaging platform to ensure proper registration.
• Mind the timing. The TCPA prohibits automated messages before 8 AM and after 9 PM in the recipient's local time zone.
• Be transparent about frequency. When someone opts in, tell them approximately how often they'll hear from you.
• Use a compliant platform. Your messaging platform should handle opt-outs automatically, include compliance features, and maintain proper 10DLC registration.

"Compliance used to scare me away from SMS marketing. But with 5CRE, everything is built in — opt-out handling, DNC checking, 10DLC registration, time zone restrictions. I just write the messages, and the platform handles the compliance." — Patricia Wong, Broker, Sotheby's International Realty

What Happens If You Don't Comply?

The consequences of non-compliance are real and costly:

• TCPA violations: $500-$1,500 per unauthorized message (class action lawsuits are common)
• DNC violations: Up to $43,792 per call/text to a registered number
• Carrier filtering: Unregistered or reported numbers get blocked, destroying your deliverability
• Reputation damage: Spam complaints damage your brand and your ability to communicate with any contact

The Bottom Line

SMS compliance in real estate isn't optional — it's a business necessity. The good news is that with the right platform and practices, staying compliant is straightforward. Register for 10DLC, get proper consent, honor opt-outs, scrub your lists, and use a platform that handles the technical compliance automatically. Do these things, and you can leverage the incredible power of SMS marketing with confidence.
