30451: Toll-Free phone number verification unable to process - address invalid

Twilio is unable to process your Toll Free Verification request because it could not be validated by Twilio and could not be submitted for verification review.

The toll-free phone number cannot be verified because the address is invalid. It could be due to:

• The provided address is not a valid US or Canada address
• Invalid State or Region
• Invalid Country
• Invalid House Number (or Unit/Apartment/Suite Number)
• Invalid City
• Invalid Postal Code
• Invalid Street
• Invalid Address - multiple issues

Correct the address and resubmit the verification in Console or via the Messaging Compliance API. It is not recommended to delete the verification to resolve address validation issue.
