Start your Twilio sign-up before you buy
Getting the missed-call text-back? Do this part first. US phone carriers make every business register before it can text customers (it's called A2P 10DLC), and their review takes a few days. Start it today and your texts are ready the day you sign up, instead of a week later.
- Your legal business name and address, as on your tax paperwork
- Your EIN (business tax ID). No EIN? You can register as a sole proprietor instead.
- Your website address, if you have one
- A card for Twilio: you pay them directly, usually a couple of dollars a month for the number, about a cent per text, plus small one-time registration fees (Twilio shows the exact amounts before you pay)
1. Create your Twilio account
- Go to twilio.com and sign up in your business's name, with an email you check.
- Verify your email and phone number when asked.
- Upgrade from the free trial: in the Twilio Console, click Upgrade account and add your card. (Trial accounts can't register for business texting.)
2. Buy a local phone number
- In the Console, open Phone Numbers → Manage → Buy a number.
- Search your area code. Pick one that shows both Voice and SMS.
- Buy it. Keeping your existing business number? Still buy one: calls you miss get forwarded to it (we explain how when you connect).
3. Register for business texting (A2P 10DLC)
In the Console, open Messaging → Regulatory Compliance (or search the Console for "A2P 10DLC") and follow the steps. There are two parts:
- Your brand: who's texting. Enter your business details exactly as they appear on your tax records. With an EIN and fewer than a few thousand texts a day, choose Low-volume standard; without an EIN choose Sole proprietor.
- Your campaign: what you text and why. When it asks, paste these (change the business name):

Campaign description
When a customer calls [Your Business] and we can't answer, we send one text to the caller so they can tell us what they need. We reply by text to schedule service or answer their question.
Sample message 1
Hi, this is [Your Business]. Sorry we missed your call! What can we help you with? If this is an emergency, call 911. Reply STOP to opt out.
Sample message 2
Thanks! When would be a good time for us to come out? You can also book here: [your booking link]. Reply STOP to opt out.
How customers opt in (message flow)
Customers opt in by calling our business phone number. When a call is missed, the caller receives one text from our business number about their call. Texts are sent only between 9am and 8pm. Every first message includes how to opt out (reply STOP) and we honor STOP immediately.
Tick that messages include opt-out (STOP) and help keywords, and that there are no links to lending, gambling or similar content (there aren't). Submit.
4. Keep these for later
On the Twilio Console home page, find your Account SID and Auth Token. After you sign up you paste them, with your new number, on your Lumière Agents page, and we set up the number's call and text settings for you. You can also connect it the same day you sign up; texts start going out as soon as the registration is approved.
One setting to change once approved: the registration puts your number in a Messaging Service. Open it → Integration → under "Incoming messages" choose Defer to sender's webhook. Without this, callers' replies don't reach your page.
Sign up any time: registration keeps going in the background.
