If you're texting customers from your tree service business in 2026 and you don't know what A2P 10DLC is, your messages may already be getting filtered, blocked, or quietly dropped by the cell carriers. And if a customer ever sues you under the Telephone Consumer Protection Act for a non-consented message, the statutory damages start at $500 per text and go up to $1,500 per text for willful violations. That math gets bad fast.
This is the side of business texting nobody warns you about until it's a problem. Here's what you actually need to know to text your customers without becoming a cautionary tale.
What A2P 10DLC Is, In Plain English
A2P stands for "Application-to-Person" — messages sent from a business application to an individual's phone. 10DLC stands for "10-Digit Long Code" — the standard business phone numbers we all use, as opposed to short codes (5-6 digit numbers like 12345 used by very large brands).
Starting in 2023, the U.S. wireless carriers (Verizon, AT&T, T-Mobile) began requiring all businesses sending A2P messages over 10DLC numbers to register their brand (your company), their campaigns (the use cases you're texting for), and their numbers through a system called The Campaign Registry (TCR). Unregistered or improperly-registered traffic gets aggressively filtered. By 2025, carrier filtering tightened to the point where unregistered business-to-consumer texts are functionally blocked.
Most tree service companies don't realize this is happening. You send a confirmation text to a new customer. You don't get a delivery receipt because text doesn't always work that way. The customer doesn't reply because they never saw the message. You think they got it. They didn't.
How to Tell If Your Texts Are Getting Blocked
The frustrating part: you usually can't, directly. Carriers don't send a polite notice saying "we filtered your message." They just don't deliver it. Symptoms include:
- Customers say "I never got that text" surprisingly often
- Reply rates from text outreach drop suddenly even though nothing changed in your messaging
- Your SMS provider's dashboard shows messages "sent" but a low or zero "delivered" rate to certain carriers
- Tests to your own phone (different carrier than your business number) don't arrive
If you're seeing any of these, get on a call with your SMS provider and ask specifically about your A2P 10DLC registration status.
What TCPA Adds On Top
A2P 10DLC is the carriers' rules. The Telephone Consumer Protection Act is federal law, enforced by the FCC and via private right of action (meaning customers can sue you directly).
Key TCPA rules for SMS:
- Marketing messages require prior express written consent from the recipient. The recipient has to have explicitly opted in — checking a checkbox on a form, signing an agreement that mentions texts, or clearly opting in via SMS.
- Informational/transactional messages (appointment confirmations, service ETAs, payment receipts) require prior express consent — lower bar, but still requires the customer to have given you their number knowingly with the expectation you'd text them.
- Opt-out requests must be honored immediately and permanently. Standard keywords are STOP, UNSUBSCRIBE, CANCEL, QUIT, END.
- Damages are $500 per text for negligent violations, up to $1,500 per text for willful violations, with no cap. A class action over 1,000 unconsented marketing texts could mean $500,000-$1,500,000 in liability.
Real cases: in 2024, a tree care company in Florida settled a TCPA class action for $2.1M over unconsented marketing texts. A landscaping company in California paid $850K in 2025 for the same thing. These are not theoretical risks. Plaintiff's law firms specialize in TCPA — the statutory damages make even small case sizes worth filing.

What Compliant Tree Service Texting Looks Like
1. Get A2P 10DLC registered
This means registering your business as a Brand with The Campaign Registry, then registering each Campaign (use case) you'll be texting for — common ones for tree service: appointment confirmations, service reminders, account notifications, marketing/promotional. Most SMS providers (Twilio, MessageBird, Bandwidth, Telnyx) handle the actual filing for you, but the responsibility for accurate information sits with you. Registration takes 1-2 weeks for the carrier review.
2. Document your consent source for every recipient
For every customer you text, you should be able to point to where and when they consented. Common compliant sources:
- Web form submission with a clear "I agree to receive text messages from [your company]" checkbox (unchecked by default — they have to actively check it)
- In-person service agreement signed at the property with a text-message consent paragraph
- Verbal agreement on a recorded phone call where the customer was told they'd receive texts (be careful — verbal consent for marketing texts is more controversial)
- SMS opt-in flow where the customer texts a keyword to opt themselves in
Save the consent record. If you're ever sued, the consent log is your defense.
3. Honor opt-outs automatically
When a customer texts STOP (or any of the standard keywords), your system should immediately stop sending and log it as a permanent opt-out. Permanent — you don't get to add them back six months later because they "forgot." Carriers track aggregate opt-out rates across your numbers and will downgrade your sending reputation if you're getting flagged a lot.
4. Don't send marketing messages to customers who only consented to transactional
The customer who gave you their number to confirm an estimate appointment did NOT consent to monthly promotional texts. Your software should track which consent type each customer is opted into, and route messages accordingly.
5. Include identification and opt-out in messages
Marketing texts should identify your business and include opt-out instructions. "Reply STOP to unsubscribe" should be in every marketing message at minimum — some advisors recommend including it in transactional messages too, just to be safe.
What Most Tree Care Software Gets Wrong About SMS
The dirty secret of the tree service software market: most platforms either ignore A2P 10DLC entirely or tell you to handle it yourself. The marketing copy says "two-way SMS!" but the implementation is "we'll let you send texts; figure out the compliance yourself."
That arrangement carries the legal risk on you, the operator. If you ever face a TCPA action, the software vendor's terms of service push the liability to you. You're holding the bag.
The right software does three things differently:
- Files A2P 10DLC registration on your behalf as part of onboarding, not an afterthought
- Tracks per-customer consent records with documented sources, automatically logged
- Enforces consent at the platform level — you literally cannot send a marketing text to a customer who hasn't opted in for marketing, because the system blocks it before it reaches the SMS provider
This is what we built into ArborDash's SMS texting. A2P registration handled during onboarding. Per-customer, per-channel consent tracking with documented sources. Automatic enforcement of opt-outs. The compliance architecture is the platform — you don't have to remember.
What to Do This Week If You're Texting Customers
- Find out if your A2P 10DLC registration is current. Email your SMS provider (Twilio, etc.) and ask for written confirmation of your brand and campaign registration status.
- Audit your consent records. For your last 50 texted customers, can you point to the source of consent (form submission, signed agreement, etc.)? If not, stop texting them until you can.
- Make sure STOP is honored. Test it. Text STOP to your own business number. If you're still able to receive a message after that, you have an opt-out enforcement problem.
- Separate marketing from transactional consent. Don't blast service reminders to people who only signed up to get appointment confirmations.
- If you're not registered or don't have consent records, consider pausing automated SMS until you've got the compliance basics in place. The cost of a TCPA suit dwarfs any short-term inconvenience.
Bottom Line
SMS is one of the most effective channels for tree service customer communication — nothing else has the open rate of a text. But the compliance layer is real, the carriers are blocking unregistered traffic, and the TCPA penalties are large enough to end small businesses. Get the registration done, track your consent, and use software that enforces compliance at the platform level rather than on you. Texting customers should be a competitive advantage, not a liability waiting to bite you.
