Text Messaging for Auto Repair Shops: Setup and Rules

How to set up texting for an auto repair shop: 10DLC or toll-free registration, consent, opt-outs under the FCC's 2026 order, quiet hours and what to text at each stage.

Text messaging for auto repair shops has gone from a nice extra to the way customers expect to hear about their car: the appointment, the inspection photos, the estimate to approve, the "it's ready" and the payment link. Getting it set up properly is less about the software than about three things owners often skip: registering the number with the carriers, getting consent, and handling opt-outs the way the rules require.

This guide covers the setup, the 2026 compliance picture (including the FCC's September 2026 order on opt-outs), quiet hours, and what to text at each stage of a visit. For ready-to-copy wording, see our auto repair text message templates.

The short answer

Text messaging for auto repair shops, in short: register your texting number for A2P 10DLC (or verify a toll-free number) through your provider, collect consent at booking or check-in, honor STOP and other opt-out words, send marketing only with written consent and between 8 a.m. and 8 p.m., and text at each stage of the visit.

Key takeaways

US carriers require business texts from 10-digit numbers to be registered (A2P 10DLC); Twilio has blocked unregistered traffic since September 1, 2023.
Registration is done through your texting provider: a brand, then a campaign; Twilio estimates under a week for campaign approval.
Service texts need consent; marketing texts sent with an autodialer need prior express written consent.
Opt-outs must be honored quickly (the 2024 FCC rule says within 10 business days); the FCC's September 2026 order lets you designate STOP-style keywords as the official method.
Keep marketing texts to daytime: federal rules bar telephone solicitations before 8 a.m. and after 9 p.m., and Florida and Maryland use 8 p.m.

Disclosure: we make BayRobin, an AI receptionist and front office for independent repair shops, and show where it fits. Everything here works without it. Figures from other companies come from their public pages, checked in October 2026 and linked at the end.

What do you need before your shop starts texting customers?

A number that can text. Your shop's existing landline number (text-enabled by a provider), a new local number, or a toll-free number.
Carrier registration for that number: A2P 10DLC for local numbers, toll-free verification for toll-free ones.
A consent step at booking, on your online booking page and at check-in, recorded on the customer.
Opt-out handling that stops texts on STOP and similar replies, automatically.
Templates for each stage of a visit, so every service writer sends the same clear messages.
One owner for the inbox: replies need answering, and a text left unread for a day is a missed call by another name.

What is A2P 10DLC, and does your shop need it?

If you text customers from a regular 10-digit number through any software, yes. Twilio's documentation describes A2P (application-to-person) 10DLC (10-digit long code) as "the standard that United States telecom carriers have put in place" for business texting, and says anyone sending SMS or MMS from an application over a 10DLC number to the US must register. Twilio's changelog states that unregistered US 10DLC messages have been blocked since September 1, 2023.

Registration has two parts, done through your texting provider (The Campaign Registry, which runs the system, doesn't take registrations from businesses directly):

Brand: your business identity, normally with your EIN.
Campaign: what you'll send, how customers opt in, opt out and get help, with sample messages.

Costs vary by provider. Twilio's published fees, checked in October 2026:

Registration type (Twilio)	Who it's for	Brand fee	Campaign fees
Low-volume standard	Businesses with an EIN sending under 6,000 segments a day	$4 one-time	$15 one-time vetting; $1.50 to $10 per campaign per month
Standard	Businesses with an EIN sending more	$44 one-time	$15 one-time vetting; $1.50 to $10 per campaign per month
Sole proprietor	Senders without an EIN; one number, one campaign	$4 one-time	$15 one-time vetting; $2 per campaign per month

Twilio estimates "under one week to get campaign approval", with no exact timeline. Most independent shops have an EIN, so the sole proprietor option won't apply. If you'd rather use a toll-free number, it has its own process: Twilio says toll-free numbers can't text US and Canadian customers until toll-free verification is complete.

If your shop software or texting tool sends texts for you, ask it three questions: whose number do the texts come from, who registered it, and under which brand?

What consent do you need to text customers?

Under the Telephone Consumer Protection Act, the FCC treats a text sent with an autodialer as a "robocall". Its rules (47 CFR 64.1200) require the recipient's prior express consent for autodialed calls and texts to a mobile number, and prior express written consent if the message includes an advertisement or is telemarketing.

Message	Type	Consent to have
Appointment confirmation and reminder	Informational	Consent to text, given when they booked
Vehicle received, inspection results, estimate link	Informational	Consent to text
Ready for pickup, invoice and pay link	Informational	Consent to text
Service due by mileage, declined-work follow-up	Often treated as informational, but can read as marketing	Written consent is the safe choice
Oil change special, seasonal promotion, review request with an offer	Marketing	Prior express written consent

A simple way to get both at once is a checkbox or a recorded yes at booking with clear wording, for example: "[Shop] may text you about your appointments and vehicle, and occasional offers, at this number. Msg frequency varies. Msg and data rates may apply. Reply STOP to opt out, HELP for help." CTIA's industry guidelines also expect the first confirmation text to name the program, give a help contact, say how to opt out and how often you'll text, and mention any fees. This isn't legal advice; have counsel or your provider check your wording.

How must you handle STOP and other opt-outs?

Since April 11, 2025, the FCC's 2024 consent order has required callers and texters to honor opt-outs made "in any reasonable manner" within ten business days, and lets you send one confirmation text, which the FCC presumes is fine if sent within five minutes. It lists the words that count when someone replies to a text: "stop", "quit", "end", "revoke", "opt out", "cancel" and "unsubscribe".

The FCC changed this again on September 30, 2026 (order FCC 26-67, released October 1). Under the new rules, which take effect 30 days after publication in the Federal Register:

You may designate an exclusive way to opt out, such as replying with one of those standard words, as long as you disclose it clearly in your texts.
If a customer opts out of one kind of informational text (say, service-due reminders), you may treat it as covering only that kind, not every informational text.
An opt-out from marketing still stops all your marketing texts.

Practically: put "Reply STOP to opt out" in your first text and in marketing texts, make sure your system stops on all seven words automatically, send one short confirmation, and record the opt-out on the customer. Check the effective date of the new order before relying on the narrower informational opt-out.

What times can you send texts to customers?

Federal rules bar telephone solicitations to residential subscribers before 8 a.m. or after 9 p.m. in the recipient's time zone. Some states are stricter: Florida bars commercial telephone solicitations before 8 a.m. or after 8 p.m., and more than three in 24 hours on the same subject, and its telemarketing law defines a sales call to include a text message; Maryland has the same 8 p.m. to 8 a.m. window and three-in-24-hours limit.

A simple house rule covers most states: send marketing between 9 a.m. and 7 p.m. local time, never more than one a day, and send service updates during business hours unless the customer is waiting on that news.

What should a shop text, and when?

Stage	What to send	Goal
Booking	Confirmation with date, time, vehicle and address	Fewer wrong-day arrivals
Day before	Reminder with a confirm or reschedule reply	Fewer no-shows (see reducing no-shows)
Check-in	"We have your car", with when to expect news	Fewer status calls
Inspection	Estimate link with photos; approve or decline each item	Faster approvals, written record
Delays	Parts or timing changes, as soon as you know	Trust
Ready	Ready for pickup, total and a pay link	Faster pickup and payment
After payment	One review request	More reviews
Between visits	Service due; declined work at about 14 and 90 days	The next visit (see service reminder texts)

How do you run two-way texting day to day?

Answer replies within the hour during business hours. Customers who text expect a text back, not a call.
Don't diagnose or quote repairs by text beyond what's on the estimate; offer a call for anything complicated.
Keep approvals in writing: an approval reply or a click on the estimate link is a record; note phone approvals with the time and who took them.
Use names and the vehicle ("your 2016 Camry") so the message is clearly from you.
Fall back to email or a call for customers who haven't agreed to texts or who opted out.

Frequently asked questions

Do auto repair shops need A2P 10DLC registration?

Yes, if you text customers from a regular 10-digit number through software. US carriers require brand and campaign registration through your texting provider, and Twilio has blocked unregistered US 10DLC traffic since September 1, 2023. Toll-free numbers need toll-free verification instead.

Can a repair shop text customers without consent?

Get consent first. TCPA rules require prior express consent for autodialed texts to mobile numbers, and prior express written consent for marketing. Collect it at booking or check-in with clear wording, record it, and include opt-out instructions.

How quickly must a shop honor a STOP text?

Under the FCC's 2024 rule, within a reasonable time not exceeding ten business days, with one confirmation text allowed. In practice, good texting systems stop immediately. The FCC's September 2026 order lets businesses designate keyword replies like STOP as the exclusive opt-out method once it takes effect.

What time can a business send text messages?

Federal rules bar telephone solicitations before 8 a.m. or after 9 p.m. local time, and states such as Florida and Maryland use 8 a.m. to 8 p.m. for solicitations. Sending marketing between 9 a.m. and 7 p.m. keeps you inside both.

What should an auto repair shop text customers?

Appointment confirmations and reminders, vehicle received, inspection results with an estimate link, delays, ready for pickup with a pay link, one review request after payment, and between visits, service-due and declined-work reminders. See our text templates for wording.
