WhatsApp fallback to SMS toggle in Messaging Services disabled for Verify customers

We’ve made some changes to help keep Verify traffic secure and your customers protected.

As of June 20, 2025, the “WhatsApp Fallback to SMS” toggle in Messaging Services is no longer supported for Twilio Verify customers. This toggle wasn’t designed to work with Verify, and we’ve identified a potential fraud risk when the two are used together.

To make things easier and safer, we’ve automatically migrated impacted customers to Verify’s own WhatsApp fallback to SMS solution. This ensures fallback SMS messages are protected by Fraud Guard and sent using Twilio-managed phone numbers for reliable delivery.

What this means for customers

• No action is needed. The migration has already happened behind the scenes.

• If a customer prefers to use their own SMS sender, or would like to turn off fallback entirely, our Support team is happy to help.
  
  

We know changes like this can raise questions, and we’re here to support you. This update is all about keeping traffic secure and making sure Verify works exactly as expected—without surprises.
