Business Texting Done Right — A2P Registration & Not Getting Blocked

The texts your software says it sent may not be arriving

U.S. carriers now require businesses that send automated texts over regular phone numbers to register — a system called A2P 10DLC, run through a central database called The Campaign Registry. The grace periods are over: as of mid-2026, unregistered business texting gets blocked, and the failure is silent. Your software says "sent." The customer's phone shows nothing. Nobody calls to tell you.

I went through the registration for Bill's Home Tech this past June. My business identity was approved in about a day. My messaging campaign was rejected more than once — first over my website's privacy policy, then over how my booking form asked permission to text — and each resubmission cost another $15 vetting fee. Nine days later it cleared, and my appointment texts have flowed since. This guide is that experience turned into a map, including the parts where I'd steer most one-person shops onto an easier road.

What A2P 10DLC means, in one breath

A2P is "application to person" — a program texting a customer on your behalf, as opposed to you thumbing a text from your own phone (which needs no registration at all). 10DLC is a "10-digit long code," meaning a regular local phone number. Put together: if software sends texts under your business's name from a normal number, carriers want you registered with The Campaign Registry first — who you are (the "brand") and what you send (the "campaign"), sample messages included, word for word.

What it costs and how long it takes (mid-2026)

• Brand registration: about $4 one-time with an EIN (about $4.50 on the sole-proprietor path for businesses without one).
• Campaign vetting: $15 — charged per submission and kept even if you're rejected. I paid it twice.
• Ongoing: roughly $1.50–$2/month for a low-volume campaign, a dollar or two for the number, about a penny per text plus small carrier surcharges.
• Timeline: brand approval is often quick; campaign review runs days to weeks. My full journey — submit, two rejections, fix, resubmit, approve — took nine days.
• Prices and rules shift; treat these as the shape of the bill and check your provider's current pricing page before filing.

The two rejection traps I hit (so you don't)

• The privacy policy. A reviewer actually visits your privacy page. It must load publicly, mention text messaging, and explicitly say mobile information isn't shared with third parties for marketing. Mine was missing the texting language — rejected.
• Forced consent. Customers must be able to book or buy from you without agreeing to texts. My booking form implied the phone number came with reminders attached — rejected. The fix: a separate, optional, unchecked "text me reminders" checkbox, with the form working either way.
• Both fixes took minutes once I understood them. Both are on the pre-submission checklist in the PDF, along with the other common failures (blank terms URL, default brand name, EIN details that don't match IRS records).

Opt-in, STOP, and playing fair

• Get clear permission before texting, and match the message to the permission — reminder opt-in is not marketing opt-in.
• STOP must always work, and since April 2025 federal rules say any reasonable opt-out counts — "please stop texting me" in plain English is a valid revocation, not just the keyword.
• HELP should return your business name and contact info. Good providers handle both keywords automatically.
• Never text someone who opted out, and never buy phone lists. (Plain-language summary, not legal advice — the TCPA has real teeth.)

The easier paths most one-person shops should take

• A managed business-phone service. Apps like Quo (formerly OpenPhone) build the registration into signup — you answer plain-English questions, they file with the registry. You still need a real privacy policy and honest opt-in; you skip the forms and the fee bookkeeping.
• Square's built-in texts. If appointment reminders are the whole wish list and you run on Square, Square Appointments sends confirmation and reminder texts with opt-in collected in its own booking flow — no carrier paperwork on your desk. See my Square and online-booking guides.
• Toll-free verification. A parallel road: text from an 833/844 number with one verification process instead of brand-plus-campaign. Higher sending limits, but unverified toll-free is blocked outright, the identity checks tightened in 2026 — and you give up the local (330) number your neighbors recognize.

So which road should you take?

My honest sorting: Square's built-in texts if reminders are all you want and you're on Square anyway. A managed service if you want real two-way business texting or a missed-call text-back without paperwork — that's the right default for most one-person shops. The do-it-yourself path (Twilio-style) only if you enjoy this stuff and want the lowest monthly cost, because the price is paid in attention — I took it, and it cost me two rejections and thirty dollars in vetting fees to learn what's now printed in the checklist. The only wrong choice is unregistered texting that silently goes nowhere.

Why I wrote this

Because I actually did this. In June 2026 I registered my own business texting for Bill's Home Tech — filled out every form, got rejected twice, fixed my privacy policy and my booking form, paid the vetting fee more than once, and watched the approval finally land nine days in. Most guides on this topic are written by companies selling texting plans. This one's written by a one-person shop in Atwater who sat on your side of the form. — Bill
