If your text messages to leads and clients are getting filtered or blocked, unregistered 10DLC is almost certainly the reason. Since 2023, U.S. carriers (AT&T, T-Mobile, Verizon) have been enforcing 10-digit long code registration for all application-to-person (A2P) SMS traffic. Real estate is one of the most scrutinized categories. This guide walks you through exactly what registration involves — and explains why most real estate professionals choose to hand it off rather than DIY it.
What Is 10DLC and Why Do Carriers Filter Unregistered Numbers?
10DLC stands for 10-digit long code — the standard local-looking phone numbers used for business texting. The Campaign Registry (TCR) is the central hub that carriers use to verify who is sending messages and why. When you send SMS through an unregistered number, carriers treat it as potential spam. The message may be delivered at reduced throughput, silently filtered, or blocked outright. You won't always get an error. The message just doesn't arrive.
Real estate is specifically called out in carrier guidelines because the category has historically attracted high complaint rates — cold prospecting texts to FSBO lists, unsolicited investor outreach, and mass drip campaigns without opt-in records. That history means your registration details and campaign description need to be precise. Vague submissions get rejected.
What Do You Need Before You Start?
- EIN (Employer Identification Number) — this is the single hardest blocker for individual agents. Sole proprietors without an EIN cannot complete brand registration. If you don't have one, you'll need to apply through the IRS (free, takes minutes online) before proceeding.
- Legal business name — must match exactly what's on your IRS EIN filing. Abbreviations or DBA names that don't match will cause brand rejection.
- Business address — a real physical address. PO boxes are not accepted.
- Business type and vertical — you'll select 'Real Estate' as your industry vertical.
- Website — carriers want to confirm you're a legitimate business. Your site should have a visible SMS opt-in disclosure and a privacy policy that mentions text messaging.
- Opt-in records or process — you need to be able to describe how subscribers consent to receive texts from you.
Individual agents operating as sole proprietors can register using their SSN in place of an EIN for brand registration on some platforms, but an EIN is strongly recommended. It keeps your personal information out of the filing and reduces the chance of a manual review hold.
Step 1: Brand Registration
Brand registration is the first layer. You're telling TCR and the carriers who you are as a business entity. This step links your phone numbers to a verified organization rather than an anonymous sender.
- 1Submit your legal business name, EIN, business type, and contact information to TCR through your SMS provider's dashboard or directly via a TCR-connected aggregator.
- 2TCR runs a verification check against business data sources (Dun & Bradstreet is commonly used). This is why your name must match your EIN filing exactly.
- 3You'll receive a brand score — a trust rating that affects how much throughput your numbers are granted by carriers. Higher scores mean more messages per second and less filtering risk.
- 4Brand registration typically takes 1–3 business days. Manual reviews can extend this to 1–2 weeks, especially for new businesses with thin credit or public data profiles.
Step 2: Campaign Registration
Campaign registration is the second layer — and where most real estate businesses get rejected. A 'campaign' in 10DLC terms is a specific messaging use case, not a marketing campaign in the traditional sense. You're describing the type of messages you send, to whom, and how recipients opted in.
- 1Select your use case. For most real estate businesses, the correct use case is 'Mixed' or a specific category like 'Marketing' or 'Real Estate.' Choosing the wrong use case is a common rejection trigger.
- 2Write a campaign description. This needs to be specific: 'We send property listing updates, appointment reminders, and follow-up messages to home buyers and sellers who have opted in via our website contact form or open house sign-in sheet.' Generic descriptions like 'SMS marketing for our business' are frequently rejected.
- 3Submit sample messages. You'll need 2–3 real examples of messages you plan to send. They must include your business name, and opt-out language (e.g., 'Reply STOP to unsubscribe') must be present in at least one sample.
- 4Confirm your opt-in method. Describe exactly how subscribers consent — web form, paper sign-in, verbal with written follow-up, etc. The opt-in method must be legally sound and actually described on your website.
- 5Campaign vetting by carriers. After TCR approval, major carriers (AT&T, T-Mobile) run their own vetting. This can add additional days and may generate further questions.
What Are the Most Common Rejection Reasons for Real Estate Campaigns?
Real estate campaigns are rejected more often than most other verticals. Here's what actually causes it:
| Rejection Reason | What It Means | How to Fix It |
|---|---|---|
| Mismatched business name | The name submitted doesn't match IRS EIN records exactly | Use your exact legal business name — including LLC, Inc., etc. |
| Vague campaign description | Reviewers can't determine your specific use case | Be explicit: who receives messages, what messages say, and why they opted in |
| No opt-out language in sample messages | Samples don't include STOP instructions | Add 'Reply STOP to unsubscribe' to at least one sample message |
| Missing privacy policy or opt-in disclosure on website | Carriers check your website and can't find compliant language | Add a privacy policy that mentions SMS and an opt-in disclosure at your web form |
| Wrong use case selection | You selected a use case that doesn't match your actual messaging | Real estate prospecting and follow-up usually falls under 'Mixed' or 'Marketing' |
| Sole proprietor with no EIN or public data | Brand verification can't confirm your business entity | Register an EIN with the IRS before submitting brand registration |
| Purchased or scraped contact lists mentioned | Any hint that you're texting contacts without their consent | Only describe opt-in methods — remove any reference to purchased lists from your submission |
How Does Carrier Vetting Work for Real Estate Use Cases?
After TCR approves your campaign, AT&T and T-Mobile conduct their own independent vetting. They're looking for evidence that your business is legitimate and that your described opt-in process actually exists and matches your website.
For real estate specifically, carriers are alert to: high-volume cold prospecting to purchased lists (not permitted under A2P rules), lead generation campaigns where the 'opt-in' is a third-party lead form the consumer filled out for a different purpose, and use cases that blur the line between conversational texting and broadcast marketing without proper consent.
This doesn't mean you can't text leads — it means your consent process needs to be real and documented. If someone submits a contact form on your site and the form includes a clear SMS opt-in checkbox, that's valid. If you bought a list from a data provider, that's not.

Why Most Real Estate Professionals Don't DIY This
The registration process itself isn't complicated, but the details are easy to get wrong — and a rejection adds days or weeks to your timeline. Common DIY mistakes include submitting the wrong use case, writing a campaign description that's too generic, or not realizing that your website's opt-in language doesn't meet carrier standards until after you've already been rejected.
There's also the ongoing maintenance side: if you change the types of messages you send, you may need to update your campaign registration. If a carrier flags your traffic, you need to respond quickly with documentation. For most agents and teams, this isn't where you want to spend time.

Frequently Asked Questions
Can I register for 10DLC as an individual real estate agent without an LLC?
Yes, but you'll need an EIN. Sole proprietors can obtain a free EIN from the IRS in minutes online. Using your SSN for business registration is technically possible on some platforms but not recommended — it creates privacy exposure and can trigger manual review holds. If you operate as an individual agent, registering as a sole proprietor with an EIN is the cleanest path.
How long does 10DLC registration take for a real estate business?
From start to finish, expect 5–15 business days if everything is submitted correctly the first time. Brand registration usually clears in 1–3 days. Campaign registration adds another 1–3 days. Carrier vetting (AT&T and T-Mobile each run independently) can add up to a week on top of that. Rejections and resubmissions extend this timeline. Having an SMS provider who prepares the submission correctly the first time makes a material difference.
What happens if I keep texting without 10DLC registration?
Your messages will be delivered at reduced throughput or silently filtered by major carriers — AT&T, T-Mobile, and Verizon. You won't always receive a delivery failure notice. Contacts may simply never see your messages, and you won't know why. Carriers have been enforcing this since mid-2023, and enforcement has tightened since then. There is no grace period for new senders at this point.
