SMS compliance & opt-in verification
Last updated: October 9, 2026
This page provides public verification of the opt-in mechanisms, Terms of Service, and messaging flows used by LeaseLine. It is designed to assist carrier auditors and messaging campaign reviewers verifying our approved A2P 10DLC campaign (Telnyx, (929) 508-0955).
Operational Model: NYC Apartment Search Alerts
LeaseLine is a New York City apartment search service by text. Renters opt in one of three ways: by texting LeaseLine first at (929) 508-0955, by entering their number and checking an unchecked consent box on leaseline.ai, or through a LeaseLine lead form on Facebook or Instagram with a required consent checkbox. Messages include apartment listings that match the renter’s search, replies to their questions, account, billing, and application updates, and occasional offers for LeaseLine’s own paid plan. LeaseLine never sells phone numbers or shares them with third parties for their marketing.
Call-to-action / message flow for carrier review
Renters opt in one of three ways. Form and lead-form sign-ups see the consent language below before they submit; renters who text in send the first message themselves. Every renter then receives an opt-in confirmation that names LeaseLine and says what they will receive, how often, that message and data rates may apply, and how to reply STOP or HELP. Form sign-ups get it in LeaseLine’s first text; renters who text in get it right after LeaseLine’s first reply.
- Text in. On https://leaseline.ai/#waitlist-signup, the homepage signup section on phones shows the "Text us" button, which opens a text to (929) 508-0955 with the message "Find me an apartment!" ready. On a Mac, a "Text us" link beside the desktop phone form opens Messages the same way. The button opens the renter’s messaging app with that pre-filled draft. The renter sends the first message; opening the draft does not send it. Right after LeaseLine's first reply, LeaseLine sends the opt-in confirmation below, with frequency, rates, and STOP/HELP instructions.
- Website phone form. On leaseline.ai, the renter enters their mobile number and checks the SMS consent box, which is unchecked by default; the form can’t be submitted without it. LeaseLine then sends the first text.
- Facebook and Instagram lead forms. LeaseLine’s lead forms require the renter to check an SMS consent box that names LeaseLine and recurring automated texts, says consent is not required to buy anything, gives message frequency, rates, and STOP/HELP instructions, and links to LeaseLine’s Terms and Privacy Policy. LeaseLine then sends the first text.
Verify the live text-in signup
Open the homepage signup sectionwhile signed out. On phones, the "Text us" button opens a text to LeaseLine's number with the first message ready. On desktop, the phone form shows its consent box, unchecked, with the details and links beside it. On a Mac, a "Text us" link beside the form also opens Messages with the first text ready. Whichever way a renter texts in, LeaseLine sends the opt-in confirmation below right after its first reply, with frequency, rates, and STOP/HELP instructions. These screenshots were captured on October 9, 2026, and show the signed-out homepage without any renter information.
1. Exact website consent language
On phones, every "Text us" button opens a text to LeaseLine with the first message ready; the renter sends it, and the opt-in confirmation with the full disclosure follows LeaseLine's first reply. On desktop, the phone form shows its consent box, unchecked, with the details and links beside it.
2. Carrier SMS flow
This shows a typical messaging flow: the consumer initiates by texting first, LeaseLine replies with the brand and compliance disclosures, and opt-out keywords are honored.
