What does it mean when you go to the bank of the check...?

Question

and try to cash it but they say that an alert popped up and they'll need to speak with the company that wrote the check first.

Answer 1

It could mean a few things:

1) the company that issued the check has told the bank branch that they need to be contacted if a check is presented.

2) That the companies bank account is what is called a "zero balance account' and the branch needs to make sure that the check will be covered.

3) The company reported that check as lost or stolen and the teller is calling to get authorization to pay (or not).
