Never use a bank box or bank ID at the request of someone who unexpectedly contacts you.
Never give out codes or other sensitive information.
If you feel unsure when someone you don’t know calls you, hang up, regardless of whether the person claims to be a close relative or is calling from a bank, business or government agency.
Do not trust the person who contacts you just because they have personal information about you.
If you experience or suspect fraud, contact your bank immediately. Always report to the police.
