4. SMS provisioning (Telnyx)

CollisionLoop uses Telnyx for outbound SMS. Toll-free numbers (8XX) require carrier verification before they can deliver to U.S. mobile networks — this guide walks through the submission.

Prerequisites

Before you start the toll-free submission:

  1. ✅ Business name, address, phone matches what’s on your state-of-incorporation filing
  2. ✅ EIN handy (encrypted server-side; we never echo it back to the browser after submission)
  3. ✅ Public Privacy Policy URL — see Privacy & T&C URLs
  4. ✅ Public Terms & Conditions URL
  5. ✅ Screenshot(s) of where customers opt in to SMS (the renter signing flow handles this automatically — we generate the screenshot)

Where to start

Settings → Messaging → SMS provisioning

The page is gated to owner-only because TF registration carries Telnyx fees and is a regulated submission.

Steps

  1. Business identity — confirm the legal name, EIN, country (US), entity type (LLC / S-Corp / etc.). Encrypted and submitted to Telnyx exactly as entered.
  2. Contact info — first name, last name, email, phone for the named submitter (must be a real person at your shop).
  3. Opt-in keywords — the keyword(s) renters can text in to opt in if they declined at sign time. Default START is fine.
  4. Privacy + Terms URLs — confirmed from Step 3 above. If empty, the submission won’t proceed.
  5. Sample messages — pre-filled with realistic copy (“Your rental is ready for pickup at 123 Main St…”). Edit if your tone is different.
  6. Submit — CollisionLoop POSTs the verification record to Telnyx. Status flips to Submitted to Telnyx.

RejectedSee the rejection reason in the page banner; fix and resubmit

If Telnyx rejects

The rejection reason appears as a banner on the SMS provisioning page. Common causes and fixes:

  • “Privacy URL does not mention SMS” — add a paragraph about SMS data collection to your privacy page
  • “Opt-in flow screenshot unclear” — the screenshot CollisionLoop submitted shows the in-app consent screen; if Telnyx wants a different angle, take one from the iOS sign-in flow and upload via the SMS provisioning page
  • “Business address mismatch” — your address must match what’s on file with the state-of-incorporation; update Settings → Tenant → Business Details first, then resubmit

After fixing, click Resubmit on the same page. A fresh verification record is sent.
