It is a number out of Nebraska, however, it is not the number that should be called back. Ususally, they leave an 800 number for you to call back and I know that it's legit because the fraud happened to someone I know. When you call the 402 number, it is not a number that can be called back, just like a neutral number for a hospital. It will say that this number can't be reached, and that's why they leave the 800 number.
NO>>>> THIS IS A SCAM CALL!!! They are wanting your credit info.. If it was the bank
(1)They would leave a message if you are not there id who they are reason for call and a number for you to call back.
(2) They would already have all your info including your social security number and other personal info.
(3) If it was your bank the number would be legit and you could get threw.
So if you answer DO NOT give or OK anything with them go directly threw your bank. They will be more than happy to assist you.Remember not just threw this number but any number wanting info on you, you do not give out over phone.
