60412: Verification blocked by Fraudulent Signup Prevention

Based on your service configuration, Twilio Verify has blocked this request because it was identified as a possible fraudulent signup attempt.

To prevent platform abuse and unnecessary costs, the verification attempt was terminated before the message was sent.

• The request was identified as a high-risk attempt to create a fake or duplicate account.
• You have not added a legitimate number to the Verify Safelist.

• Update your Safelist: Add the phone number to your Verify Safelist. This prevents active filters from blocking this specific phone number.
• Override it using the risk_check parameter: If you're sure that this authentication is legitimate and safe, you can bypass the block by including the risk_check=disable parameter in your API request.
  • Note: Disabling risk checks increases your exposure to SMS pumping and fake account creation.
• Adjust Fraudulent Signup Prevention Setting: While the feature is in pilot, contact your account manager or reach out to support to adjust the prevention mode.
