my friend owed me $$ her husband is a truck driver. She paid me in the form of a com check. It has my name the amount and her husband,s account number.

When i called the number its asking for a company number or something i'm not sure... Where is says account/express code there's a 10 or 12 digit number...

Is this correct ???

And how do i cash it ??
