Property management runs on texting — rent reminders, maintenance windows, renewal nudges, showing confirmations. In 2026, every one of those texts gets blocked or filtered unless the number sending them is A2P 10DLC registered.
A2P means application-to-person: any text sent by software (your property-management platform, CRM, or follow-up tool) rather than typed by a human. 10DLC is the ordinary 10-digit local number it comes from. AT&T, T-Mobile, and Verizon require every business sending A2P texts to register with The Campaign Registry: a Brand (who you are) and a Campaign (what you text, with real samples). Registered traffic gets delivered. Unregistered traffic gets blocked or silently filtered.
Two reasons. Anything money-adjacent gets extra scrutiny — carriers treat debt-collection texting as a restricted category, and a rent reminder written with late-fee threats pattern-matches straight into it. And portfolio texting is spiky: a number that idles mid-month, then fires a thousand reminders on the morning of the first, looks exactly like a freshly spun-up spam operation. Registration plus pacing keeps a legitimate property-management operation deliverable through the cycle.
You file through your messaging provider (Twilio, Telnyx, Bandwidth, or the texting feature inside your PM software), which passes it to TCR. Three things trip most applications:
Register the management company once — you are the sender; the properties are what you text about. A self-managing landlord without an EIN can register as a sole proprietor, but that path caps throughput hard and only makes sense for a handful of units.
The campaign describes what you send and shows the vetter real samples. Rent reminders alone are Customer Care — but the moment you also send renewal offers or referral asks, that is marketing content. So register Mixed (or Low Volume Mixed) and include both message types in your samples.
| Use case | Fits when | Monthly |
|---|---|---|
| Low Volume Mixed | Reminders + occasional offers, under ~6,000 segments/day | ~$1.50–2 |
| Mixed | Same content, larger portfolio volume | ~$10 |
| Customer Care only | Strictly service messages — no promos, ever | ~$1.50–2 |
Two planning numbers: vetting takes days to weeks, so register well before you need the number live — and once vetted, your brand is assigned a trust tier that sets a daily sending cap. A typical small management company lands a tier comfortably above its reminder volume, but it is the cap your first-of-month pacing has to respect.
“Summit Property Management sends transactional and informational messages to current residents and scheduled prospects: rent due reminders, maintenance appointment updates, lease renewal notices, and showing confirmations. Recipients provide consent in writing at lease signing or via our resident portal. Reply STOP to opt out, HELP for help.”
Notice what is missing from the good ones: no ALL CAPS, no link shorteners, no “act now.” Every sample carries opt-out language.
“Friendly reminder: rent is due on the 1st” from the manager the resident already pays is customer care. Threats and urgent-pay language turn the same message into a restricted use case. Vetters read tone.
Spread reminders over the 28th–30th instead of one 8 a.m. blast on the 1st. Velocity checks flag spikes even on registered numbers.
Add a texting-consent line to the lease and portal onboarding, and archive it. “Signed at lease, here’s the record” ends any complaint conversation.
Campaign-per-building is wasted money and a vetting mess. One Mixed campaign covers the portfolio.
A water-shutoff notice is customer care at any hour; a renewal promo at 9 p.m. violates quiet-hours rules in several states. Know the texting rules for your state.
Collect consent in writing at lease signing, confirm the number at move-in, honor STOP instantly and permanently, keep HELP working. Residents rarely opt out of messages that save them a missed maintenance window — opt-outs come from promos sent too often. Service messages build the trust that makes the occasional renewal offer land.
On Twilio, unregistered A2P traffic to US numbers fails outright with error 30034. Elsewhere, messages silently vanish into carrier filtering — the worst failure mode in this business, because a resident who never got the maintenance-window text is a resident calling angry at 5 p.m. In property management, deliverability is an operations metric, not a marketing one.
FollowUp sidesteps the registration project two ways. On the Pro tier, messages send through your own iPhone number via iMessage — person-to-person delivery for smaller portfolios, no registration required. On the Autopilot tier, sends go out on a dedicated business number that is already A2P 10DLC registered, with quiet hours and opt-outs enforced automatically, and an AI that reads every reply so only the ones needing a human reach you. See how it works for property managers.
Yes. Any property manager sending business SMS to US numbers through software (rent reminders, maintenance updates, lease renewals, showing confirmations) from a 10-digit local number must register a brand and campaign with The Campaign Registry. In 2026, Twilio blocks unregistered traffic with error 30034 and AT&T, T-Mobile, and Verizon filter whatever slips through elsewhere.
Brand registration is $4 one-time. Campaign registration costs approximately $15 in one-time vetting plus roughly $1.50 to $12 per month depending on use case. A typical management company sending rent reminders, maintenance updates, and renewal notices fits Low Volume Mixed (about $1.50 to $2/month) or Mixed (about $10/month) at higher volume. Register once for the management company, not per property.
A routine reminder that rent is due, sent by the property manager the resident already pays, is customer care, not third-party debt collection. But wording matters: threats, late-fee pressure, and urgent-pay language make carriers and vetters read it as collections, which is a restricted use case. Keep reminders service-toned and factual, and the campaign vets cleanly.
It can. A number that sends a few dozen texts most days and then thousands on the first trips carrier velocity checks even when registered. Spread rent reminders across a two-to-three-day window, stay inside your trust tier’s daily cap, and keep the copy identical-but-personalized rather than one mass-pasted message.
Get texting consent in writing at lease signing or in your onboarding portal, and keep the record. A resident who gave you their number for their tenancy is a defensible audience for service messages, but marketing (renewal offers, referral promos) needs clear opt-in, and anyone who replies STOP stays suppressed. TCPA and state quiet-hours rules apply on top of 10DLC.
