If the PIN generation does not work

If you do not receive an OTP, wait for at least 5 minutes before trying again. Ensure your mobile network is strong and that you have not blocked SMS alerts from the bank.

If the digital methods fail after multiple attempts, visit an AU Bank branch or call the helpline at 1800 1200 1200. If you have a complaint that the bank does not resolve within 30 days, you can escalate it. You may approach the Reserve Bank - Integrated Ombudsman Scheme, 2026 (RBI, 2026).
