Business Text Messaging: What It Is and How to Get Your Number Set Up

By Anthony, Founder of LightningVoIP · Published September 9, 2026

Customers increasingly expect to text a business the same way they call or email it. Setting that up is very doable, but there is one step almost no one knows about until they hit it: your number has to be registered and approved before it can send a single text. Here is exactly how business texting works, what the registration involves, and how we take that whole process off your plate.

What business text messaging is

Business text messaging lets your company send and receive texts with customers using your business phone number, not someone's personal cell. It is most often used for customer service and order-related updates rather than advertising. If a customer places an order, you can text them to confirm it, tell them when it ships, and answer questions, all from the same number they already have for you.

Done right, texting becomes another support channel that sits alongside phone and email, and it is the one a lot of customers now prefer for quick, order-related questions.

How businesses actually use it

The most common use cases are simple and practical:

• Order confirmations. A quick text when an order is received.
• Shipping notifications. A heads-up, with a tracking link, when it ships.
• Delivery updates. "Out for delivery today," or a reschedule notice.
• Customer service. Customers reply to ask a question, and your team answers by text.
• Inbound texts. Customers text your business number first, the same way they might email.

Here is what those messages look like in practice:

Transactional vs. marketing texts

This distinction matters, because it decides how your texting has to be set up. The use cases above are transactional (also called customer-care) messaging: orders, shipping, delivery, appointment reminders, and answers to questions the customer asked about.

Marketing texting is different. That is when the main purpose is to send promotions, sales, or offers. Marketing programs face stricter registration and stricter consent rules, and one rule matters especially: a customer should never be required to accept marketing texts as a condition of buying from you. If you only want order updates and support, keep the setup focused on that, it is simpler and approves faster.

Why you can't just start texting: 10DLC registration

This is the step that surprises almost everyone. You cannot flip a switch and text customers from a business number. Since 2023, US carriers require every business to register before its number can send texts. The process is called 10DLC (10-digit long code), and it exists to cut down on spam and confirm that a real, identified business is behind the texts.

There are two parts:

1. Register the business (the "brand")

You provide who your business is:

• Legal business name
• Brand or DBA name, if you use one
• EIN (required)
• Business address
• Business website
• Business industry
• A contact name, phone, and email

A working business website helps here, because the registration may be reviewed. The EIN is not optional, it is how the system ties the texting to a real, registered business.

2. Describe how you will use texting (the "campaign")

Then you describe the messaging program: why you are texting, what kinds of messages you will send, how customers give permission, and a couple of real sample messages. For an order-and-support program, a clear description reads something like: "This program sends order confirmations, status updates, shipping and delivery notifications, and customer-service replies related to products the customer requested."

How customers give permission (opt-in)

The single most important piece of the registration is showing how customers agree to receive your texts. Common, acceptable ways a customer opts in:

• Enters their mobile number at checkout and agrees to order updates
• Checks an SMS consent box when placing an order or creating an account
• Asks customer service for help by text
• Sends the first text to your business

If you collect consent online, your form should spell out what people are agreeing to. A standard consent line looks like this:

The wording should match how you actually collect the number, and a separate SMS consent checkbox is recommended when you gather consent on a form. Your disclosure should say what the texts are about, that frequency may vary, that message and data rates may apply, and how to stop (reply STOP).

Managing the messages: by hand or connected to your systems

You do not need a big integration to get started. There are two common setups:

Handle texts manually

Someone on your team reads and replies to customer texts from a simple messaging portal. This is perfect when your text volume is modest, which is most small businesses starting out.

Connect texting to another system

If you want texts to flow automatically to or from your online ordering system, CRM, help desk, or phone system, that can be connected. The exact setup depends on the software, and it is something we scope with you rather than a one-size box.

What the whole process looks like

1. Register your business (the brand).
2. Describe your messaging program (the campaign).
3. Show how customers consent to receive texts.
4. Submit two sample messages.
5. The registration is reviewed and approved.
6. Your business number is enabled for texting.

Realistically, plan for the review and approval to take a few weeks, and a little extra time to attach the number to the approved program. It is not hard, but it is not instant, which is exactly why it pays to start before you actually need to text customers.

Business texting is an add-on, and we set it up for you

At LightningVoIP, business texting is an add-on we enable on your existing business number. More useful than that: we do the 10DLC registration for you. You hand us your business details and how you plan to use texting, and we handle the brand registration, the campaign, the sample messages, the consent wording, and getting your number switched on, then we set it up to be managed by hand or connected to your systems, whichever fits.

What we'll need from you to start

When you're ready, having these handy makes it fast:

• Business details. Legal name, DBA if any, EIN, address, website, industry, and a contact name, phone, and email.
• How you'll use texting. What you'll send, how customers give you their number, and how they consent.
• Two sample messages using your real business name.
• The business number you want to use for texting.
• How you want to manage it. Your team replies by hand, or connect it to an ordering system, CRM, or phone system.
