21741: Brand Registration Failure: 2FA Code Expired

This error occurs when the Authentication+ PIN sent to the brand contact expires before the contact completes verification. Complete 2FA within the time window provided in the verification email.

• The brand contact did not enter the verification code before it expired.
• The verification attempt happened after the deadline in the 2FA email.
• The verification email was missed or not acted on before the code expired.

• Re-initiate the 2FA process and ask the brand contact to complete verification before the code expires.
• If the brand contact did not receive the verification email, resend the Authentication+ email from the Twilio Console.
• If the contact email is incorrect or needs to be updated, update brand_contact_email in the us_a2p_messaging_profile_information bundle and trigger verification again.
• If you are using the API for a failed new Brand registration, create a new 2FA verification request with the Brand 2FA Verification endpoint after you update the brand contact details.
