10DLC for Small Business: A Complete Compliance Guide
Confused about 10DLC? Learn what it means for small business texting, who must register, what it costs, and how to stay compliant in 2026.
What Is 10DLC?
10DLC stands for 10-digit long code — a standard 10-digit phone number that's been registered with mobile carriers specifically for business texting. Unlike a personal number, a 10DLC number is tied to your business identity and approved for Application-to-Person (A2P) messaging, which is any text your business sends through software rather than typing it manually from a phone. Carriers introduced 10DLC to cut down on spam and scam texts, and today it's the standard way nearly every legitimate small business sends SMS in the United States.
Does My Small Business Need to Register?
Yes — in almost every case. Registration isn't just for companies running large marketing campaigns. If your business uses any kind of software, app, or platform to send text messages to customers, you're sending A2P traffic, and carriers expect that traffic to be registered. Company size and message volume don't exempt you.
- Appointment reminders sent automatically from scheduling software
- Two-way texting with customers from your business number
- Order, shipping, or service-status updates
- Promotional or marketing texts to your contact list
- Any text sent from a shared business line, not a personal cell phone
If any of the above sounds like your business, you need 10DLC registration before you send your next message — not after.
How A2P 10DLC Registration Works
Registration happens through The Campaign Registry (TCR), the centralized body that carriers use to vet business texting traffic. The process has two parts: registering your brand, then registering your specific messaging campaign.
Step 1 — Register Your Brand
This verifies your business identity. You'll need your legal business name, EIN or tax ID, business address, and website. Carriers use this information to assign your business a trust score, which determines how many messages per second you're allowed to send.
Step 2 — Register Your Campaign
Next, you register the type of messages you plan to send — for example, customer care, appointment reminders, or marketing. You'll also submit a sample message and confirm how customers opt in to receive texts from you.
Step 3 — Get Approved and Start Texting
Most small business registrations are approved within a few business days, though timelines vary by carrier and campaign type. Once approved, your number is cleared to send through standard 10DLC at your assigned throughput.
What Does 10DLC Registration Cost?
Costs vary by provider, but most small businesses pay a one-time brand registration fee plus a small recurring monthly carrier fee per campaign — typically far less than the cost of a dedicated short code, which can run into the thousands of dollars per month. Some providers, including Dial Raven, build registration into the cost of the platform itself so there's no separate bill to manage.
10DLC vs. Toll-Free Numbers vs. Short Codes
| Type | Best For & Approval Time & Relative Cost | ||
|---|---|---|---|
| Type | Best For | Approval Time | Relative Cost |
| 10DLC | Most small businesses; calls + texts from one local number | A few business days | Low |
| Toll-Free | Businesses that want a recognizable 800/888 number | 1–2 weeks (carrier verification) | Low–Medium |
| Short Code | High-volume national campaigns (banks, large retailers) | Several weeks | High |
For the vast majority of small businesses, 10DLC is the right fit — it lets you keep your existing local number for both calls and texts, which is exactly what most customers expect.
What Happens If You Don't Register
Unregistered business texts increasingly get filtered, delayed, or blocked outright by carriers — meaning appointment reminders don't arrive and customer replies never reach you. Beyond delivery issues, non-compliant texting can expose your business to real financial risk. Several states have recently passed or strengthened laws around unsolicited business texts, and the regulatory environment continues to tighten in 2026. Registering isn't just a formality — it protects message delivery and reduces legal exposure.
Business SMS Compliance Checklist
- Register your brand and campaign with The Campaign Registry before sending any A2P messages
- Get clear, documented opt-in consent before texting a customer
- Include your business name in your first message
- Make opt-out easy — honor "STOP" requests immediately
- Avoid restricted content categories (certain financial, legal, or health claims)
- Keep your registration details current if your business name, use case, or volume changes
- If you're in a regulated field like healthcare, build in extra safeguards around what patient information can be sent by text
DIY Registration vs. a Managed Provider
You can register directly with The Campaign Registry yourself, but the process involves carrier-specific terminology, trust scoring, and ongoing maintenance if your use case changes. Many small business owners find it simpler to let their phone and texting provider handle registration as part of onboarding — particularly when that provider can also manage the business SMS platform itself, not just the paperwork.
