A customer books an appointment and then forgets it. Another wants to know whether their order is ready. A third is a regular who hasn't walked in for six weeks. One text message solves all three problems in about ten seconds, which is exactly why so many small businesses have leaned on texting for reminders, confirmations, and quick promotions.

There's a catch, and in the last two years it has quietly cost businesses real customers. Your texts can be filtered, throttled, or blocked outright unless you've completed the registration that mobile carriers now require. The work isn't difficult, but it has to be done correctly, and several rules changed again in 2026. Here's what a small business needs to know to get compliant, stay compliant, and actually reach the phone in a customer's pocket.

Why Your Texts Might Already Be Disappearing

When you send a message from a business number to a customer, the carriers classify it as A2P messaging, short for application-to-person. The number itself is a 10DLC, a standard ten-digit long code. Carriers use that classification to separate legitimate business traffic from bulk spam, and since February 1, 2025, the major U.S. carriers stopped delivering unregistered 10DLC traffic entirely. Not filtered at the margins. Blocked.

That distinction matters because a lot of owners never got the memo. If a tool or platform encouraged you to "just start texting customers," your messages may be failing silently. You see a send confirmation on your end while the customer sees nothing at all. Before you build any strategy around texting, confirm that your messages are actually arriving.

The Two Registrations You Actually Need

Registration happens through The Campaign Registry, the industry database carriers check before delivering a message. There are two parts, and both are required before a single marketing text goes out to a U.S. mobile number.

The first is brand registration, which establishes who you are. You'll submit your legal business name exactly as it appears on IRS records, your EIN, your business type, and your website. As of 2026, the EIN must be at least 15 days old before it will be accepted, so brand-new businesses need to wait a beat before registering.

The second is campaign registration, which describes how you plan to use texting. You provide the use case, several sample messages, estimated monthly volume, and the URL where customers opt in. That opt-in page has to be live and verifiable by the carrier, so a placeholder link will sink the application.

In most cases your messaging provider submits both on your behalf. Expect brand approval in two to five business days and full campaign approval anywhere from one to four weeks, depending on how complex your use case is and how long the carrier review queue is running.

On cost, plan for a small one-time brand fee plus a vetting fee, and a modest monthly charge per campaign with carrier surcharges on top. Publicly traded companies also need the deeper Authentication+ verification tier. Two things are worth remembering here: the fees are non-refundable even when a registration is rejected, and a hard rejection means you pay the vetting fee again before your clock restarts. Getting the details right on the first pass is cheaper than rushing.

Consent Is the Part That Gets Businesses Sued

Delivery is only half the job. Consent is the other half, and it carries the real financial risk. The Telephone Consumer Protection Act requires prior express written consent before you send promotional texts, and the burden of proving that consent falls on you. A purchased list with no documentation is not a shortcut; it is a stack of per-message liability.

The rules tightened on January 27, 2026, when the FCC's one-to-one consent requirement took effect. Consent can no longer be shared across brands or sold to third parties, and each seller must collect separate, explicit consent from each consumer. A single lead form that funnels signups to five different companies now satisfies the consent requirement for none of them. If your opt-in flow aggregates leads, it needs an audit before you send another message.

Two more guardrails protect you. First, honor opt-outs immediately. When someone replies STOP, that number comes off your list, with real-time processing as the standard. Second, respect quiet hours: federal rules prohibit marketing texts before 8 a.m. or after 9 p.m. in the recipient's local time zone. Statutory damages run from $500 to $1,500 per message with no cap on aggregate liability, so a few sloppy sends to a large list is not a rounding error.

What to Send Once You're Approved

Compliance clears the runway, but it doesn't make a message worth reading. Texting earns its reputation on engagement, with open rates well above 90% and response rates that dwarf email's roughly 6%. That attention is a loan, not a gift. Messages that feel relevant and expected get answered; messages that feel like broadcast advertising get the STOP reply and never come back.

The messages that consistently work for small businesses look like this:

  • Appointment reminders and confirmations that invite a one-word reply to reschedule
  • Order-ready and status updates that save a phone call in both directions
  • Waitlist and cancellation-fill offers that turn a no-show into a booked slot
  • Reactivation nudges to past customers who haven't been in for a set number of weeks
  • Review requests sent an hour or two after a job is marked complete

Keep each message short, identify your business by name, include one clear action, and always leave the opt-out language visible. The platforms handle most of that automatically once the campaign is registered, but the tone is yours to set.

A Realistic Plan to Get This Done This Month

None of this requires a developer or a large budget. It requires about an afternoon of setup and a few days of waiting on approval. Here is a sequence that works.

Start with an audit. Pull your last 90 days of sent texts and find out how many actually delivered, not how many were queued. If delivery is low or unknown, registration is your first priority.

Next, gather the registration inputs: EIN, the legal name that matches IRS records, your website, your privacy policy, and a live opt-in page. Write your campaign description and three or four sample messages, including the opt-out line, before you begin the application.

Then register the brand, followed by the campaign, through your provider. While that processes, build consent capture into every channel you own: website forms, checkout, intake paperwork, and in-person signups. The language should be clear, and it should state that consent is not a condition of purchase.

Finally, configure quiet hours and automatic opt-out handling inside the platform. Set the sending window to something conservative, like 9 a.m. to 8 p.m., so a time-zone mistake can't create a violation. Once delivery is confirmed and consent is documented, texting becomes what it always should have been: the fastest, most direct channel a small business has for reaching the people who already know it.
