What is 10DLC and Why Does It Matter?

Let’s start with the basics. 10DLC stands for “10-Digit Long Code,” a messaging standard in the US for sending A2P (Application-to-Person) SMS and MMS. US carriers require all A2P messaging traffic—like OTPs, alerts, and marketing messages—to go through registered 10DLC numbers or approved alternatives (like toll-free or short code). This ensures better deliverability, higher throughput, and compliance with carrier rules.

Why is 10DLC important?

If you try to send A2P messages without proper 10DLC registration, your messages may be blocked, filtered, or flagged as spam. That’s why understanding the 10DLC timeline and 10DLC registration time is critical for a smooth A2P campaign setup.

The Real 10DLC Timeline (And Why It Drags On)

Let’s break it down, step by step. Here’s what usually happens when you try to get your OTPs live with 10DLC: 

1. Brand Registration (TCR)
   
   • What’s involved: You’ll submit your business details—EIN, legal company name (as per IRS records), address, and contact information—to The Campaign Registry (TCR).
   • 10DLC registration time: Usually minutes to 1 business day if everything matches.
     Pro tip: Even a small mismatch (like “Inc.” vs. “Incorporated”) can cause delays and manual reviews.

2. Secondary Vetting
   
   • What’s involved: Carriers may conduct additional checks to verify your brand’s legitimacy, use case, and website. This often includes reviewing your privacy policy, opt-in and opt-out flows, and overall business presence.
   • 10DLC registration time: This step can take 7–14 business days, especially if documentation is missing or unclear.
   • Common pitfalls:
     
     • Missing or inconsistent business information
     • No clear consent or privacy policy on your website
     • Use case descriptions that are too vague

3. A2P Campaign Setup
   
   • What’s involved: You’ll define your campaign’s purpose (e.g., OTP, alerts, marketing), provide sample messages, and outline your opt-in/opt-out process. Carriers want to see exactly how you’ll use SMS and how users can control their experience.
   • A2P campaign setup time: Typically, 2–5 business days, but can be longer if templates are rejected or require revision.
   • Tips for success:
     
     • Use clear, compliant language in your templates
     • Always include opt-out instructions (e.g., “Reply STOP to unsubscribe”)
     • Make sure your use case matches carrier guidelines

4. Number Provisioning
   
   • What’s involved: Once your brand and campaign are approved, you’ll be assigned a 10DLC long code or toll-free number. This is the number your users will see when they receive messages.
   • Provisioning time: 1–2 business days.
   • Tip: If you’re in a hurry, toll-free numbers sometimes provision faster than 10DLC, but both require proper vetting.
5. Test & Go Live
   
   • What’s involved? Time to send test messages! Make sure your OTPs, alerts, or marketing messages are being delivered as expected. Monitor delivery rates and check for any carrier filtering.
   • Go-live time: If all previous steps are smooth, you can be live within 1–3 weeks. But if there’s a snag, the process can stretch to a month or more.

Why Do So Many Startups Get Stuck With 10DLC Delays?

Let’s get real—most delays in the 10DLC timeline are due to documentation hiccups or campaign setup errors. Here are the most frequent culprits:

• EIN and Legal Name Mismatch: Your EIN must match your legal name exactly as registered with the IRS. No exceptions.
• Inconsistent Business Details: Your business name, address, and website must be consistent everywhere.
• Missing Website Info: Carriers look for a privacy policy, terms of service, and clear opt-in/opt-out information.
• Vague Campaign Descriptions: Be specific! “OTP for user login” is better than “user messages.”
• Template Rejections: Missing opt-out instructions, non-compliant content, or unclear formatting can all lead to rejections.
