Check your current and old credit card statements for blank checks. If checks are available, write a check to "Cash" with the desired amount. Take it to your bank or check cashing establishment to receive cash for the check amount.
Use your credit card in an ATM to retrieve cash from your available cash advance limit. To do this you require a pin number for your credit card. If you do not have a pin number, contact the 800 number on the back of your card to request one.
Take your credit card to any bank and request a cash advance on your card. The teller will run the card as if it were a purchase and give you cash in return. You will need to provide a driver's license with a physical address (not a PO Box) and sign a credit card slip to receive the cash.
