A2P 10DLC Registration Explained for RV Repair Shops

RV owners drop the rig and leave. They are at work, at home or three campgrounds down the road when you need a yes on the estimate, and a text reaches them faster than a voicemail. So when a shop sets up business texting and finds it can’t send anything yet, the delay feels like red tape.

It is red tape, but it exists for a reason, and getting through it is mostly about telling the truth clearly. This guide explains what A2P 10DLC registration is, why US carriers require it, what an RV shop has to provide, how consent and STOP work, and how long it really takes.

What A2P 10DLC means#Link to the section “What A2P 10DLC means”

A2P stands for application-to-person: a text sent from software rather than typed on someone’s phone. 10DLC is a 10-digit long code, an ordinary local phone number. Twilio describes A2P 10DLC as the standard US carriers put in place so that messages sent to US customers from these numbers are verified and consensual.

Regular local numbers were built for person-to-person texting. As spam moved onto them, carriers responded with registration: every business sending from software has to say who it is and what it sends before its messages are delivered normally. Registrations go to The Campaign Registry (TCR), an industry registry that businesses reach through their messaging provider rather than directly.

If your shop texts customers from any system on a computer, including a shop management system, you are sending A2P traffic. Twilio says carriers treat all SMS sent through its platform as coming from an application, and since September 1, 2023 Twilio has blocked messages to US numbers from unregistered 10DLC numbers.

Brands and campaigns: the two halves of registration#Link to the section “Brands and campaigns: the two halves of registration”

Registration has two parts, and both have to clear before your messages flow normally:

• The brand is your business: who is sending.
• The campaign is your messaging program: what you send, why, and how customers opt in, opt out and get help.

Twilio’s own guidance for software platforms is that the business sending the messages is the one that gets registered, not the software company. Your customers should see your shop’s name, and so should the registry.

What an RV shop needs to provide#Link to the section “What an RV shop needs to provide”

For the brand#Link to the section “For the brand”

Most shops register as a standard or low-volume standard brand, which needs a federal tax ID. Twilio’s list of required business information includes:

• Your legal business name exactly as registered with your EIN. Twilio points to the IRS CP 575 confirmation letter, or a 147C letter if you lost it, and warns that W-2 or W-9 names can differ.
• Your EIN, business type (corporation, LLC, partnership and so on) and industry.
• Your business address.
• A website that loads, belongs to your business and isn’t parked, for sale or behind a login.
• An authorized contact: name, title, email and phone.

If you’re a sole proprietor without an EIN#Link to the section “If you’re a sole proprietor without an EIN”

A sole proprietorship with no EIN registers as a sole proprietor brand instead. Rather than a tax ID, the owner verifies a real mobile number by replying to a one-time code, and Twilio says that number can be used no more than three times across all registrations with TCR. The trade-off is lower limits: one campaign per brand and, per Twilio, 1,000 messages a day to T-Mobile customers, roughly 3,000 a day across US carriers. That is plenty for most one-truck mobile techs. If you do have an EIN, TCR requires you to register as a standard or low-volume brand instead.

For the campaign#Link to the section “For the campaign”

The campaign describes your messaging program. Expect to provide:

• A use case and a plain description: who sends, who receives and why.
• The message flow: exactly how customers opt in, written so a reviewer can verify it.
• Two or more sample messages that name your shop and match what you’ll really send, including any links.
• Your opt-out and help behavior, plus whether messages contain links or phone numbers.
• A privacy policy and terms on your website that cover texting.

The texts an RV shop actually sends#Link to the section “The texts an RV shop actually sends”

Service texting is mostly informational: messages about the customer’s own rig, sent because they asked for updates. Typical messages include:

Promotional texts, such as a spring de-winterizing special or a coupon, are a different category. The CTIA Messaging Principles and Best Practices, the guidelines the wireless industry follows, say a customer should agree in writing before receiving promotional texts, and that adding a promotion to an informational text can turn it into a promotional one. If you want to send marketing by text, it needs its own written consent and a campaign registered for it. Keep it out of your service messages.

Consent: how customers opt in#Link to the section “Consent: how customers opt in”

Reviewers look hardest at consent. CTIA’s guidelines tie the kind of consent to the kind of message: conversational replies to a customer who texted you first, informational messages such as appointment reminders with the customer’s express consent, and promotional messages with written consent.

For an RV shop, consent usually happens at the counter or on the phone when you take the customer’s number. Say what they’ll get, in the same words every time, and record their answer. A counter script can be as simple as:

“We’ll text you updates about your repair from this number, like when your estimate is ready to approve and when your rig is ready for pickup. Message frequency depends on the work. Message and data rates may apply. Reply STOP any time to stop, or HELP for help. Is that okay?”

That covers the points CTIA asks a call to action to make clear: who is sending, what the messages are for, any charges, and how to opt out and get help. Publish the same wording on your website so a reviewer can verify it, and never make consent to texts a condition of doing the repair.

Opt-out and help: STOP has to work#Link to the section “Opt-out and help: STOP has to work”

A customer can end the conversation at any time, and the rules are not subtle about it. Under the FCC’s TCPA rules in effect since April 11, 2025, replying “stop,” “quit,” “end,” “revoke,” “opt out,” “cancel” or “unsubscribe” counts as revoking consent, a customer can also revoke it by any other reasonable means, and a revocation has to be honored within a reasonable time not exceeding ten business days. The FCC allows one confirmation text that only confirms the opt-out and contains no marketing. CTIA’s guidelines say the same in practice: send one final confirmation, then nothing more. On September 30, 2026 the FCC adopted further changes to how revocations work (FCC 26-67), which take effect 30 days after they are published in the Federal Register and keep the ten-business-day limit. Check the current rules, or ask counsel, if you’re building your own system.

In practice:

• Treat STOP and its variations as final, whatever the capitalization.
• Answer HELP with your shop’s name and how to reach you.
• If a customer tells your advisor in person to stop texting, record it the same way.
• Call or email instead. Opting out of texts should never affect the repair.

How long registration takes#Link to the section “How long registration takes”

Honestly: it varies, and anyone who promises a fixed date is guessing. Twilio’s own documentation gives a range. The automated brand check with TCR typically happens within minutes, but a brand that needs manual review can take seven business days or more. Campaign vetting is a manual review, and Twilio’s guidance has described it as taking anywhere from about a week to two or three weeks, depending on how many campaigns are in the queue.

A rejection restarts part of the clock, so the fastest path is a registration that is right the first time: exact legal name, working website with a privacy policy, consent described as it really happens, and sample messages that match your real ones. Start before you need to send your first estimate by text, not after.

How RVDesk handles registration#Link to the section “How RVDesk handles registration”

In RVDesk, each shop gets its own local number, registered with the carriers in the shop’s business name rather than shared with other shops. RVDesk collects the information the registration needs and files it for you, and the status shows on your Integrations screen the whole way through. Consent is collected the way a shop actually works, at the counter when the customer gives you their number, and the wording is published on a page of your own so a reviewer can verify it. STOP is honored automatically, and a customer who has opted out can’t be texted by mistake.

Once registration clears, two-way texting puts customer replies in one place against the customer and the job, and estimates go out as a link the customer can approve from their phone.
