7 Tips for a Successful A2P 10DLC Registration with SimpleVox

7 Tips for a Successful A2P 10DLC Registration with SimpleVox

If you’re planning to text U.S. customers through SimpleVox, you’ll need to complete A2P 10DLC registration — a carrier-required process to verify your business and ensure your texts get delivered.

We've helped many users successfully register, and we’ve learned what works (and what causes frustrating delays or rejections). In this post, we'll walk you through the most important tips to make sure your A2P application is approved on the first try.

1. Match Your Business Info Exactly

For business registrations (with an EIN), your submitted information must match what’s on file with the IRS or equivalent authority:

  • Use your full legal business name
  • Enter the correct EIN and U.S. business address
  • Avoid abbreviations or DBAs unless they are officially registered

Mismatches are the #1 reason applications get rejected or flagged for manual review.

2. Sole Proprietors: Use a Valid Mobile Number

Registering without an EIN? You’ll go through the Sole Proprietor path.

To qualify, you’ll need:

  • A U.S. or Canadian mailing address
  • A real mobile number (not a VOIP line or your SimpleVox number)

This number is used for validation and must be capable of receiving SMS messages.

3. Provide a Legitimate Use Case

Your campaign description helps carriers understand how you plan to use SMS for your business.

✅ Good examples:

  • “We send job reminders and arrival ETAs to customers.”
  • “Used to confirm appointments and follow up after services.”

🚫 Avoid:

  • “Bulk marketing”
  • “Customer blasts”
  • Anything vague or overly generic

Clear, honest use cases build trust — and improve approval times.

4. Have a Privacy Policy in Place

All registrants — even sole proprietors — must have a privacy policy that explains how you collect and use customer data, especially SMS consent.

You have two options:

Option 1: Add a Snippet to Your Existing Privacy Policy

If you already have a policy (on your website, booking page, etc.), just add a section that states:

“We do not share your phone number or SMS consent information with third parties. By providing your number, you agree to receive messages related to your service, appointment, or inquiry.”

This satisfies the carrier requirement for transparency.

Option 2: Let SimpleVox Generate One for You

When you submit your registration just let us know you don't have one and we'll generate a lightweight privacy policy hosted by SimpleVox for you. You’ll be able to use this link in your A2P registration form.

5. Document How You Collect Consent

Carriers want to know that you’re only messaging people who explicitly opted in. During registration, you’ll be asked how you collect consent.

These are acceptable methods:

  • Verbal consent (e.g., “Can I text you when the technician is on the way?”)
  • Written consent (e.g., on a sign-in sheet or job form)
  • Digital consent (e.g., booking forms with a checkbox)
  • Text-to-subscribe (e.g., “Text JOIN to 123-456-7890 to receive updates”)

Be prepared to explain your method — and make sure it aligns with your business practices.

6. Upload a Clean, Recent Phone Bill (for ported numbers)

If you’re porting a number into SimpleVox, you may need to upload a recent phone bill to verify ownership.

Make sure it clearly shows:

  • The phone number
  • Your name or business name
  • Billing address
  • Account number

Avoid cropped or low-quality images — clear documentation avoids delays.

7. Use a Website or Public Listing for Verification

While not always required, having a business website, Yelp page, or Google Business listing improves your chances of quick approval. It gives carriers a way to verify your legitimacy during manual review.

Don’t have a site? Even a Facebook page with your business name and contact info works.

8. Know the Fees Involved

These fees go directly to The Campaign Registry and the major U.S. carriers — SimpleVox does not mark them up:

  • $19 - One-time application review fee (covers two-stage review)
  • $1.50–$2/month - Ongoing carrier registration fee
  • $15 - Resubmission fee if your application is rejected

9. Watch Your Email After Submitting

Once submitted, your application goes through two stages:

  1. Automated validation
  2. Manual carrier review (for most campaigns)

We’ll notify you via email if anything is missing or needs updating — so be sure to check your inbox (and spam folder).

Final Thoughts

Registering for A2P 10DLC may seem like just another step, but it’s key to:

  • Keeping your texts delivered and trusted
  • Avoiding spam filters and message blocking
  • Staying compliant with U.S. carrier regulations

By following these tips, most SimpleVox users get approved in 3–5 business days with no hiccups.
