Will the credit card company tell you your expiration date over the phone?

My mother(in FLA at the moment) has a credit card that she wants to use to buy me a train ticket with but the card is at home so she would have to call the number in and pay over the phone. She knows the number since she got it off of the billing statement, but does not have the expiration date since that is not displayed there. If she calls the company, would they tell her the expiration date over the phone?|||doubtful - the "caller" could be someone who stole the teh card number and just needs the exp date to be able to use it
