Twilio and the SMS carriers (Verizon, AT&T, T-Mobile, etc.) are now requiring registration of phone numbers and campaigns (what type of messages you are sending) to reduce filtering. Their goal is to prevent SMS from becoming water logged with spam like phone calls have become. Read more about this from Twilio here.

Follow the steps in this guide to register your business and Twilio phone number.

5. Now that you've created business profile click on Go to A2P Messaging.


6. Click on Continue registration.


7. Select Company Type Private and agree to the registration fee.


8. You'll then be given a TCR score, unless your score is below 60 don't worry about the score. Click Continue.


9. You'll now create a messaging service and assign it to a number. Name your messaging service something like ABC Cleaners SMRT Service and select Notify my users for the Messaging Service use case.
On the next page you'll select the phone number you want to connect to the service.


10. You'll now register a campaign.
