How to Text-Enable Your Business Landline

Your customers already text the number on your website, your van, and your Google profile. If that number is a landline, most of those texts go nowhere. The customer thinks you are ignoring them, and you never knew they wrote. Landline texting fixes that gap: it lets your existing number send and receive texts, while your voice calls carry on as before.

The texts you never see: what happens when a customer texts your landline today

A traditional landline cannot receive text messages. It was built for voice calls, and the network behind it has nowhere to put an incoming text. In most cases the carrier drops the text without notifying either party: your customer gets no error, and you get nothing at all. A shrinking few convert it to an automated voice call, and some return a failure notice.

Think about when those texts arrive: a homeowner at 9pm whose boiler has stopped, or a renter sending a photo of a leak while at work. Neither will ring again to check whether the text landed. They will simply try the next business. That is the quiet cost of an untextable landline.

What landline texting actually is (hosted messaging, in plain English)

Landline texting, sometimes called hosted messaging, adds texting to a number that was never built for it. A provider hosts the texting side of your number, while your phone company keeps carrying your voice calls.

To your customers, nothing looks different. They text the same number they have always called, and your replies come from that same number. You read and reply in an app or a web dashboard, and staff can share the same inbox. Best of all, you keep the number: no new cards, no van repaint, no updating every listing.

The 4 steps: pick a provider, prove you own the number, carrier verification, activation

Step 1: pick a provider. Choose one that supports your number, offers a shared inbox and photo messaging, and handles the registration paperwork for you.

Step 2: prove you own the number. The provider will ask for a recent phone bill in the business name, plus a signed Letter of Authorization saying it may enable texting on that number.

Step 3: carrier verification. The provider submits your number and paperwork to the carriers, who check the number can be text-enabled and the business is legitimate. This is also where your business gets registered for A2P 10DLC — see our guide to what A2P 10DLC is.

Step 4: activation. Once the carriers approve the number, texting goes live. Test it yourself first: text the number from a personal phone, reply from the inbox, and confirm the reply arrives.

The paperwork: Letter of Authorization, phone bill, and 10DLC registration

The paperwork is the part most businesses are not expecting, but none of it is difficult. The Letter of Authorization is a short signed form giving the provider permission to text-enable your number. The phone bill is proof of ownership: it must show the number and the business name, and it usually needs to be recent.

Then there is 10DLC registration. 10DLC stands for 10-digit long code, and it is how US carriers tell a genuine business sender from a spammer. Your provider registers your business and the kind of messages you plan to send. This is not optional: unregistered business texting is filtered, delayed, or blocked. Registration also ties into consent: marketing texts need consent, and you must stop when someone opts out. Our guide to whether it is legal to text back a missed call explains the difference.

How long it takes and what it costs (up to 2 weeks; from $29/month at SlickText)

Text-enabling an existing number usually takes up to two weeks, depending on the number and the registration requirements. Some are approved in a few days; others take the full two weeks, usually because carrier verification or 10DLC registration needs more information. Start a fortnight before you need it.

On price, SlickText's paid plans start at $29/month. Prices checked November 2026 — verify on the vendor's own page. What you pay depends on your message volume and the features you need. There is also a cost to doing nothing: every text that vanishes is a customer who may never call, and a single recovered job a month will usually pay for the service several times over.

What changes for your customers — and what stays exactly the same

For your customers, the biggest change is that texting you finally works. They can send a photo of the problem, confirm a time, or ask a quick question without a phone call. Many customers expect this.

For you, the change is a new inbox to watch. Treat it like a second phone line: somebody needs to own it during working hours, and replies need to be quick. What stays the same is everything your customers rely on. Your number does not change, and your voice calls keep running through your existing provider unchanged.

Landline texting vs a new mobile number: which one to choose

Text-enabling your landline is the right choice when your number is already everywhere: on your website, your van, and your Google profile. Keeping it means keeping years of trust, and every customer who already has you saved can text you without learning anything new.

A new mobile number is better in narrower cases. If your landline is rarely called and your business is starting fresh, a mobile number gives you texting and calling in one place, with no setup wait. The question is simple: which number do your customers already have? If it is your landline, text-enable it.
