Customers increasingly expect to text a business the same way they text a friend — asking about an order, confirming an appointment, or getting a quick answer without sitting on hold. Setting up two-way texting lets your team send and receive those messages from a dedicated business number instead of a personal cell phone.

This guide walks through choosing the right texting setup, registering your number so messages actually get delivered, and avoiding the compliance mistakes that get businesses blocked by carriers before they even get started.
Quick Answer
Pick a business texting platform (or a text-enabled VoIP/landline number), register your business for A2P 10DLC compliance so carriers don’t block your messages, collect proper opt-in consent from customers, and connect the number to a shared inbox so your whole team can reply.
Step 1: Choose How You’ll Text
You have two basic paths. The first is text-enabling a number you already use, such as a VoIP business line or, in some cases, an existing landline — several providers offer this as an add-on so you keep your current number but gain texting ability. The second is signing up for a dedicated business texting platform that issues you a new local or toll-free number built for messaging.
For a solo operator or very small team, a free or low-cost tool like Google Voice can cover basic back-and-forth texting. For a team that needs multiple people replying from the same number, read receipts, templates, or integration with a CRM or helpdesk, a dedicated platform (examples include OpenPhone, Textline, SimpleTexting, or EZ Texting) is worth the cost. Pricing structures differ by provider and change over time: some bill per user per month, while others sell tiered plans built around a bundled allotment of message credits, with extra seats, phone numbers, or credits beyond that allotment billed separately. Rather than assuming a simple per-seat price, check each provider’s current plan page directly, since tiers and what’s included in each one shift fairly often.
Step 2: Register for A2P 10DLC Compliance
If you plan to send business texts from a standard 10-digit number to U.S. customers, your business needs to complete A2P (Application-to-Person) 10DLC registration through The Campaign Registry. This involves registering your business as a ‘Brand’ (legal name, EIN, business type, website) and then registering a ‘Campaign’ describing your use case and message types.
This isn’t optional paperwork you can skip — major U.S. carriers now block unregistered business texting traffic outright, meaning your messages simply won’t arrive if you haven’t registered. Most texting platforms walk you through this registration inside their dashboard, and approval generally takes anywhere from a few days to a few weeks, so start this step early rather than the day you plan to launch.
If you expect very high message volume, ask your provider whether a short code or toll-free number makes more sense than a standard 10-digit number, since those have different registration paths and throughput limits.
Step 3: Get Consent and Connect Your Team
Before texting any customer, you need their opt-in — typically captured through a checkbox on a website form, a checkout flow, a sign-in sheet, or a reply to an initial opt-in text. Keep a record of when and how each customer opted in, since carriers and regulators can require proof.
Once your number is live, connect it to a shared inbox so multiple team members can see and respond to the same conversation thread without stepping on each other. Most platforms support canned responses or templates for common questions, automated away messages outside business hours, and keyword handling for opt-outs like STOP and HELP, which carriers require you to honor automatically.
If you use a CRM, help desk, or scheduling tool, check whether your texting platform integrates directly — logging conversations against a customer record saves your team from re-explaining context on every reply.
Tips and Common Mistakes
Don’t start sending high volumes of texts before your A2P registration is approved — you risk messages being silently blocked or your number getting flagged. Don’t text customers who haven’t opted in, even with a friendly reminder; unsolicited texts can create legal exposure, not just annoyance. Avoid running marketing blasts and one-on-one support replies through the exact same unlabeled thread, since customers can get confused about what they’re responding to. Set a realistic response-time expectation (even an auto-reply saying when a human will follow up) rather than letting texts sit unanswered, since customers who text generally expect a faster reply than email. Finally, keep your opt-in consent records and message templates documented somewhere your whole team can reference, not just in one person’s head.

Frequently Asked Questions
Can I text customers from my existing business phone number?
Often yes — many VoIP providers and some landline carriers offer text-enabling as an add-on so you keep your current number. If that’s not available, a dedicated texting platform will issue you a new number instead.
Is two-way business texting free?
Basic tools like Google Voice are free or very low-cost for light use, but dedicated business texting platforms charge for their shared-inbox and automation features. Some bill per user per month, while others sell tiered plans built around a bundled allotment of message credits, with overage fees once you exceed that bundle — so check a provider’s current plan page rather than assuming a single pricing model.
Do I really need to register for A2P 10DLC?
Yes, if you’re sending business texts from a standard 10-digit number to U.S. customers. Carriers block unregistered traffic, so skipping registration means your messages won’t be delivered.
How fast should I respond to customer texts?
There’s no universal rule, but customers who text generally expect quicker replies than email — many businesses aim for responses within minutes during business hours and use an automated message to set expectations outside those hours.
