How to Submit Your Carrier Registration

What Our Phone Number Configuration Form Asks (and Why)

  1. Registration status
    • Already registered? You’ll skip straight to phone number configuration.
    • Not registered? You’ll enter your business details so we can register you.
  2. Choose your phone configuration
    • Purchase new:
      • Local 10DLC
      • Toll-free
    • Connect existing:
      • Local 10DLC
      • VoIP/Landline (host texting only, voice stays with your provider)
      • Toll-free
Twilio users: Complete carrier registration in your Twilio account first, then connect those numbers to MessageDesk. You won’t re-register through our form.

​
What You’ll Need to Register (Quick Checklist)

  • Legal business name (exactly as filed, incl. LLC/Inc)
  • EIN and business address (or sole-prop info if no EIN)
  • Website or public listing (Facebook, Yelp, etc.)
  • Use-case description (what you’ll send)
  • Three sample SMS messages (include “Reply STOP to opt out” in at least one)
  • Consent method (web form checkbox, written/verbal, keyword)
**Note: **Are you a Sole proprietor with an EIN? You’ll need to complete manual TCR verification with our team (see our Carrier Registration Overview guide).

​
After You Submit

  • **Status updates: **Our team will contact you directly once you submit your registration request.
  • Estimated completion time:
    • Business (EIN): ~1–3 business days
    • Sole Proprietor (no EIN): ~5–7 business days
    • Toll-Free Verification: ~1–2 weeks
  • Sending while pending: Until you complete carrier registration and configure your phone numbers, you are unable to send or receive text messages.

​
Tips to Speed Approval

  • Make sure your website shows the same legal name and address you submit.
  • Include opt-out language (“Reply STOP…”) in at least one sample message.
  • Describe exactly what you plan to send (e.g., “appointment reminders and service updates”).
  • For toll-free, submit one form per number to verify each line.

If You’re Rejected

  • Our Team will let you know, and we’ll help resubmit on your behalf. We’re here to help you fix it once and get approved.
