60424: Contact address not found

This error occurs when your Verify request references a contact, but Twilio cannot find the phone number or email address needed for the verification. Verify sends verifications to a phone number or email address, so the contact must contain a valid destination for the channel you selected.

• The contact does not include a phone number or email address for the requested verification channel.
• The contact has an address, but your application selected a different channel than the address supports.
• The phone number stored on the contact is not in E.164 format for a phone-based verification.

• Update the contact so it includes the correct destination address for the channel you are using.
• If you are verifying a phone number, store the contact's phone number in E.164 format before you retry the request.
• If you are verifying by email, add a valid email address to the contact and send the verification with the email channel.
• Validate both the selected channel and the contact address in your application before you create the verification.
