30752: Brand Registration Failure: Invalid or expired OTP

This error occurs during Sole Proprietor A2P Brand verification when the OTP used for brand verification is invalid or has expired. Twilio sends the verification request to the mobile number registered with the Brand after the Brand reaches APPROVED. The Brand remains UNVERIFIED until the mobile number owner completes the verification step. The OTP is valid for 24 hours.

• The mobile number owner did not complete the OTP verification within 24 hours, so the OTP expired.
• The verification attempt did not use the current valid OTP for the Brand verification request.
• The mobile number owner did not reply YES to the verification message sent to the registered mobile number, so the Brand verification did not complete.

• Ask the owner of the registered mobile number to complete the verification message and reply YES. After the reply is received, identity_status changes to VERIFIED.
• If the OTP has expired, request a fresh OTP from Console or by creating a Brand Registration OTP through the API. Then complete verification with the latest OTP request.
• Check the Brand status before proceeding. Wait for the Brand to reach APPROVED, then confirm that identity_status changes from UNVERIFIED to VERIFIED after verification completes.
