Your Texts Aren't Delivering. Fix A2P 10DLC This Week.
YOUR TEXTS AREN'T DELIVERING. FIX A2P 10DLC THIS WEEK.
Your appointment confirmations aren't all landing. Your estimate follow-ups, payment links, and membership reminders — a chunk of those texts are getting filtered or blocked before customers ever see them. And you don't know which ones.
THE PROBLEM
As of March 18, 2026, Twilio began tying MMS throughput to Brand Trust Scores and campaign use cases. T-Mobile applies daily message caps at the brand level — tied to your EIN. If you're unvetted, you might be capped at 2,000 messages per day across all T-Mobile subscribers, shared across every platform you use.
When you hit that cap, messages just stop delivering until midnight Pacific. No warning. You just go silent on a third of your customer base.
WHAT IS A2P 10DLC?
A2P = Application-to-Person (any text sent by software on behalf of a business)
10DLC = Ten-Digit Long Code (your regular local phone number)
The carriers decided businesses sending texts from local numbers need to register through The Campaign Registry (TCR). Tell them who you are, what you're sending, and prove you have consent.
THE REGISTRATION FIX
STEP 1: REGISTER YOUR BRAND
Cost: $4.50 one-time through TCR
What you need:
* Your EIN (legal name must match IRS records exactly)
* Business address
* Website with visible privacy policy and SMS consent language
* Support phone number and email
* Two sample messages that match what you actually send
STEP 2: CREATE A CUSTOMER CARE CAMPAIGN
Cost: $2-10/month depending on your category
Covers: Confirmations, reminders, estimates, invoices, membership notices
STEP 3: UPDATE YOUR WEBSITE
Add this consent language to every form where customers enter phone numbers:
> "By entering your mobile number and clicking submit, you agree to receive SMS messages from [Your Company Name] related to your appointments, estimates, and account. Message frequency varies. Message and data rates may apply. Reply HELP for help, STOP to opt out."
STEP 4: ALIGN YOUR TEMPLATES
Every automated text needs STOP and HELP keywords at the end. Your sample messages submitted to TCR must match your actual templates in Jobber, Housecall Pro, or ServiceTitan.
Template Examples:
* Confirmation: "[Name], it's [Company]: your [Service] on [Day] [Time]. Tap to confirm or reschedule: [link]. Reply STOP to opt out, HELP for help."
* Estimate follow-up: "[Name], it's [Company]. Your estimate for [Service] is ready: [link]. Reply 1 with a day/time to schedule. STOP to opt out, HELP for help."
* Past-due reminder: "[Name], friendly nudge from [Company]: invoice [#] for [Service] is [$$] and past due. Pay here: [link]. Questions? Reply. STOP to opt out, HELP for help."
STEP 5: USE VERIFIED TOLL-FREE AS A BRIDGE
While 10DLC approval processes (up to 7 business days for brand vetting), move time-sensitive confirmations to a verified toll-free number. Pending toll-free traffic has been blocked since January 31, 2024.
CHECKING DELIVERY STATUS
Jobber: Insights → Reports → Client Communications Report
Housecall Pro: Automatic consent confirmations; delivery failure alerts in Notification Center
ServiceTitan: Chat/Phones Pro message threads; contact Support for delivery status details
TEMPLATE RULES
* Text-only for confirmations and follow-ups (highest delivery rates)
* Use your branded domain for links (avoid bit.ly and other shorteners)
* Keep images under 5MB if you must include them
* Include STOP/HELP on every automated message
WEEKLY TARGETS (ADVISORY)
* Delivery rate: 95%+ per carrier
* Confirmations within 60 minutes: 80%+
* Estimate follow-up reply rate: 5-15%
If AT&T is at 97% but T-Mobile is at 82%, you've got a carrier-specific cap issue.
THIS WEEK'S ACTION
The question you need to answer: Do you have a verified toll-free number live right now, and do your website consent language and SMS templates match the campaign you're registering?
If the answer to either is no, that's your Monday morning.
