don’t answer when scammers come calling.
…. we’ve become aware of a widespread scam targeting bank customers nationwide, including ours. Please use caution when discussing your bank accounts over the phone as you could be chatting with a scammer, disguised as an Ally Bank employee. Keep in mind, while we do make follow-up calls occasionally, we don’t call our customers out of the blue.
Here are 4 ways you can outwit the scammer.
Verify only your name and secret question.
When Ally calls you, we’ll only ask to verify your name and secret question. Do not provide any additional account details.
Ask questions.
Asking questions like “When’s the last time I called you?” may prompt the fraudster to hang up.
Deny requests for a one-time passcode.
We’ll never call you and ask if we can text you a one-time passcode to verify your account. These scammers will.
Call us directly if something feels suspicious.
Our Ally Bank Customer Care representatives welcome callbacks. You can reach us 24/7 at 1-877-247-2559.
