You’ve just launched a brilliant SMS marketing campaign to engage your customers, but suddenly your messages aren’t getting through. Your delivery rates have plummeted, and your business is losing valuable connections with customers every single day. Sound familiar? 📉

If you’re sending business text messages using standard 10-digit long codes (those regular phone numbers), you’re navigating a landscape that changed dramatically—and if you haven’t registered for A2P 10DLC, you’re likely facing serious deliverability issues right now.

Welcome to the world of A2P 10DLC, a messaging framework that’s become absolutely essential for businesses in 2026. Whether you’re running a small local shop or managing enterprise-level communications, understanding and implementing A2P 10DLC isn’t just recommended—it’s mandatory for effective business texting.

Key Takeaways

  • A2P 10DLC stands for Application-to-Person 10-Digit Long Code, a system designed to legitimize business SMS messaging and improve deliverability
  • Registration is mandatory for all U.S. businesses sending commercial text messages through standard phone numbers
  • Message deliverability improves dramatically after proper A2P 10DLC registration—up to 95% delivery rates
  • Carrier filtering became stricter in 2024-2025, making unregistered numbers nearly useless for business messaging
  • The A2P 10DLC setup process involves registering your business, creating campaigns, and getting carrier approval
  • Costs range from $4-$15 monthly per campaign, plus one-time brand registration fees around $4-$39
  • Failure to register results in blocked messages, carrier penalties, and potential phone number suspension
  • Higher throughput limits allow registered businesses to send 4,000+ messages daily versus 200-500 for unregistered numbers

Understanding A2P 10DLC in Simple Terms

Let’s break down what A2P 10DLC actually means, because the technical jargon can be intimidating at first glance.

A2P = Application-to-Person (automated messages sent from a business application to a person’s phone)

10DLC = 10-Digit Long Code (a standard phone number like you’d normally use)

In essence, A2P 10DLC is a registration system that tells mobile carriers “Hey, this regular-looking phone number is being used by a legitimate business to send automated messages, not spam.” It’s the wireless industry’s answer to the flood of unwanted robotexts that plagued consumers for years.

Why Did A2P 10DLC Become Necessary

Before A2P 10DLC, businesses and bad actors alike used regular phone numbers to blast out text messages. Mobile carriers couldn’t easily distinguish between your legitimate appointment reminders and a scammer’s phishing attempt. This created massive problems:

  • Consumers were bombarded with spam texts 📱
  • Legitimate business messages got caught in filters
  • Carriers had no way to manage or monitor business messaging traffic
  • Businesses faced unpredictable delivery rates

In response, major U.S. carriers (AT&T, T-Mobile, Verizon, and others) partnered with The Campaign Registry (TCR) to create the A2P 10DLC ecosystem. Launched in stages from 2021-2023, with full enforcement hitting hard in 2024, this system transformed how business texting works in America.

Why Your Business Absolutely Needs A2P 10DLC Registration in 2026

If you’re still questioning whether A2P 10DLC registration is worth your time, let me be crystal clear: it’s not optional anymore. Here’s what happens when you register versus what happens when you don’t.

The Reality of Unregistered Numbers

Businesses attempting to send text messages without A2P 10DLC registration face:

Severely limited throughput – Only 200-500 messages per day maximum
Blocked messages – Carriers actively filter unregistered business traffic
Message fees – You still pay for messages that never reach recipients
Number suspension risk – Carriers can permanently block your phone number
Compliance violations – Potential legal issues under TCPA regulations
Terrible customer experience – Your customers never receive critical updates

The Advantages of Proper Registration

Once you complete the A2P 10DLC setup process, you unlock:

Dramatically higher throughput – 4,000-75,000+ messages per day depending on your trust score
Superior deliverability – 90-95%+ delivery rates consistently
Brand recognition – Carriers recognize your business as legitimate
Better customer engagement – Messages actually reach your audience
Compliance confidence – You’re following carrier and federal requirements
Scalability – Grow your messaging programs without technical limitations
Competitive advantage – While competitors struggle, your messages get through

According to recent industry data, businesses with proper A2P 10DLC registration see average delivery improvements of 40-60% compared to their pre-registration rates. That’s potentially thousands of customers actually receiving your messages every single day.

How the A2P 10DLC Registration Process Actually Works

Ready to get your business registered? The A2P 10DLC setup process involves several distinct steps, each serving an important purpose in validating your business and messaging use case.

Step 1: Choose Your Campaign Service Provider (CSP)

You can’t register directly with carriers—you need to work through a Campaign Service Provider. These are messaging platforms authorized by The Campaign Registry to submit registrations. Popular CSPs include:

  • Twilio
  • Bandwidth
  • Sinch
  • GoHighLevel (perfect for agencies and service businesses)
  • Plivo
  • Telnyx

Many businesses already use these platforms for their communication needs. If you’re working with Hexalevel’s CRM SaaS Setup services, A2P 10DLC registration is typically included in the implementation process.

Step 2: Register Your Business Brand

This is the foundation of your A2P 10DLC registration. You’ll need to provide:

📋 Legal business name (must match official records)
📋 Business type (corporation, LLC, sole proprietorship, non-profit)
📋 EIN or Tax ID number
📋 Business address
📋 Business website (very important for trust scoring)
📋 Industry vertical
📋 Contact information
📋 Stock ticker (for publicly traded companies)

Cost: Brand registration typically costs $4 for sole proprietors or $39 for registered businesses (one-time fee, plus $4-$9 annual renewal).

Processing time: 1-5 business days for most standard businesses, though sole proprietors may experience longer review periods.

💡 Pro tip: Having a professional, legitimate business website significantly improves your trust score and approval likelihood. If your website needs enhancement, consider Hexalevel’s Website Redesign services to ensure you make the best impression.

Step 3: Create Your Messaging Campaign

Once your brand is registered, you’ll create specific “campaigns” for each type of messaging use case. Each campaign requires:

Campaign Details:

  • Campaign name and description
  • Messaging use case (marketing, notifications, account updates, etc.)
  • Sample message content (actual examples of what you’ll send)
  • Opt-in/opt-out processes
  • Message volume estimates
  • Terms and conditions URL
  • Privacy policy URL

Available Use Cases:

  • Customer care
  • Account notifications
  • Marketing/promotions
  • Higher education
  • Political campaigns
  • Public service announcements
  • Sweepstakes
  • Charity/non-profit

Cost: Campaign registration runs $4-$15 per campaign per month, varying by carrier and CSP.

Processing time: Most campaigns are approved within 1-2 business days.

Step 4: Wait for Carrier Approval and Trust Score Assignment

After submission, The Campaign Registry reviews your information and assigns a trust score to your brand. This score determines your message throughput limits:

Trust ScoreDaily Message LimitTypical Brand Type
High200,000-250,000 messages/dayEstablished corporations, publicly traded companies
Medium40,000-75,000 messages/dayVerified businesses with strong credentials
Low/Standard4,000-6,000 messages/dayMost small-to-medium businesses
Sole Proprietor2,000-3,000 messages/dayUnincorporated businesses

Even the lowest tier provides dramatically better throughput than unregistered numbers, making the A2P 10DLC registration absolutely worthwhile.

Step 5: Link Your Phone Numbers

After campaign approval, you’ll associate your 10-digit phone numbers with your approved campaigns. Each number can typically be linked to multiple campaigns, giving you flexibility in your messaging strategy.

Breaking Down A2P 10DLC Registration Costs for 2026

Let’s talk money, because understanding the investment helps you budget appropriately and see the ROI clearly.

One-Time Registration Fees
  • Brand registration: $4 (sole proprietor) or $39 (registered business entity)
  • Brand vetting (optional but recommended for higher trust scores): $40-$299
Recurring Monthly Costs
  • Campaign fees: $4-$15 per campaign per month
  • Brand renewal: $4-$9 annually (yes, annually not monthly!)
  • Phone number hosting: Varies by CSP, typically $1-$2 per number
Example Cost Scenarios

Small Business (Single Campaign):

  • Brand registration: $39 (one-time)
  • Campaign fee: $10/month
  • First year total: $159
  • Subsequent years: $120/year

Growing Business (3 Campaigns):

  • Brand registration: $39 (one-time)
  • Campaign fees: $30/month (3 campaigns × $10)
  • First year total: $399
  • Subsequent years: $360/year

Enterprise (Multiple Brands & Campaigns):

  • Multiple brand registrations: $39-$299 each
  • Campaign fees: $10-$15 per campaign
  • Costs scale with messaging complexity
The ROI Perspective

While these fees might seem like an added expense, consider this: if your unregistered numbers are only delivering 30-40% of your messages, you’re essentially throwing away 60-70% of your SMS marketing budget on messages that never arrive. A2P 10DLC registration pays for itself almost immediately through improved deliverability.

Common A2P 10DLC Registration Challenges and How to Overcome Them

Based on thousands of business registrations, here are the most common roadblocks and their solutions.

Challenge 1: Brand Verification Delays

Problem: Your business information doesn’t match public records, causing verification delays or rejections.

Solution:

  • Ensure your business name matches exactly what’s on file with your Secretary of State
  • Verify your EIN is correct and active
  • Update your business website to clearly display your company name and contact information
  • Consider professional brand vetting ($40-$299) for faster approval
Challenge 2: Low Trust Scores

Problem: Your brand receives a low trust score, limiting your message throughput.

Solution:

  • Register as a formal business entity (LLC, Corporation) rather than sole proprietor
  • Maintain an active, professional website with clear business information
  • Build your business credit and establish a track record
  • Pay for third-party brand vetting services
  • Ensure all submitted information is accurate and complete
Challenge 3: Campaign Rejections

Problem: Your messaging campaign gets rejected for vague descriptions or problematic content.

  • Ensure you have documented opt-in and opt-out processes
  • Include proper disclosure language in your samples
  • Host your terms of service and privacy policy on your website
  • Avoid prohibited content like cannabis, debt relief, or get-rich-quick schemes
Challenge 4: Understanding Use Case Categories

Problem: Businesses struggle to categorize their messaging appropriately.

Solution:

  • Customer Care: Support requests, service updates, appointment confirmations
  • Account Notifications: Order updates, shipping alerts, security notifications
  • Marketing: Promotional offers, sales announcements, newsletters
  • When in doubt, separate different messaging types into distinct campaigns
Challenge 5: Technical Integration Issues

Problem: Connecting your CRM or marketing platform to your registered campaigns seems overwhelming.

Solution: This is where working with experts makes all the difference. Platforms like GoHighLevel offer built-in A2P 10DLC support, but proper configuration matters. Hexalevel’s API & Third-Party Integration services ensure your messaging infrastructure works seamlessly from day one.

A2P 10DLC vs. Other Messaging Options: What's Best for Your Business

A2P 10DLC isn’t the only way to send business text messages. Let’s compare it to other options so you can make an informed decision.

A2P 10DLC (10-Digit Long Codes)

Best for: Most businesses with regular customer communications

Pros:

  • Looks like a normal phone number
  • Two-way conversations
  • Can receive calls and texts
  • Local area codes available
  • Cost-effective for moderate volume

Cons:

  • Requires registration process
  • Monthly campaign fees
  • Message throughput limits (though generous for most businesses)
Short Codes (5-6 Digit Numbers)

Best for: Large enterprises with high-volume messaging needs

Pros:

  • Extremely high throughput (100,000+ messages per minute)
  • Highest deliverability rates
  • Premium brand appearance

Cons:

  • Very expensive ($500-$3,000/month plus setup fees)
  • 6-12 week approval process
  • Cannot receive phone calls
  • Less personal than standard phone numbers
Toll-Free Numbers

Best for: Businesses wanting nationwide presence without A2P registration complexity

Pros:

  • Higher throughput than standard numbers
  • No local area code needed
  • Familiar format for customers

Frequently Asked Questions About A2P 10DLC

What happens if I don't register for A2P 10DLC?
Unregistered business numbers face severe limitations in 2026. Mobile carriers actively filter unregistered traffic, meaning your messages will be blocked or heavily throttled to just 200-500 per day. Worse, carriers may permanently suspend numbers that consistently violate messaging policies. Essentially, without registration, your business texting won’t work reliably.
The complete A2P 10DLC registration typically takes 5-10 business days from start to finish. Brand registration usually processes in 1-5 days, followed by campaign approval in 1-3 days. Sole proprietors may experience longer review times (7-14 days) as they undergo additional verification. Rush services are available through some CSPs for urgent situations.
Yes! One phone number can be associated with multiple approved campaigns, which is actually recommended for businesses with diverse messaging needs. For example, you might have separate campaigns for marketing promotions and appointment reminders, both using the same business phone number. This provides flexibility while maintaining compliance.
Low-volume typically means under 1,000 messages per day and is suitable for most small businesses. High-volume (4,000-250,000 messages daily) requires proper A2P 10DLC registration with good trust scores. The tier you need depends on your business size, industry, and messaging frequency. Most businesses start low-volume and scale up as needed.
Yes, you need registration for ALL business messaging, whether marketing, transactional, notifications, or customer service. The type of messaging determines your campaign category (which affects approval and compliance requirements), but registration itself is mandatory regardless of message content.
Expect to invest approximately $50-$200 in the first year for a typical small business (brand registration + one campaign for 12 months). Subsequent years cost $120-$180 annually. Enterprise businesses with multiple brands and campaigns will invest more, but costs remain reasonable compared to the value of functional business messaging.
Brand registration is portable across Campaign Service Providers (CSPs), meaning you can switch providers without re-registering your business. However, you’ll need to recreate campaigns with your new CSP and may face brief downtime during the transition. Choose your provider carefully, as frequent switching creates administrative headaches.
A2P 10DLC registration applies specifically to U.S. domestic messaging. International SMS follows different rules and carrier requirements depending on the destination country. If you need to reach customers abroad, discuss international messaging capabilities with your CSP, as requirements vary significantly by region.

Conclusion

The messaging landscape has fundamentally changed, and businesses that ignore A2P 10DLC registration are essentially operating with one hand tied behind their backs. Your competitors who’ve completed their A2P 10DLC setup process are reaching customers consistently, building stronger relationships, and driving better results while unregistered businesses watch their delivery rates plummet.

Here’s what we’ve covered: A2P 10DLC registration is no longer optional for U.S. businesses sending text messages. The A2P 10DLC setup process, while involving some paperwork and modest costs, unlocks dramatically better message delivery, higher throughput limits, and compliance with carrier requirements. The investment is minimal compared to the cost of messages that never reach your customers.

Whether you’re sending appointment reminders, marketing promotions, or critical account notifications, proper registration is your ticket to reliable, scalable business messaging in 2026 and beyond.

The choice is simple: Take a few days now to complete your A2P 10DLC registration, or continue struggling with blocked messages, frustrated customers, and wasted marketing dollars.
