How do I make a text entry valid only once?

At the start of my survey I have a text entry question where only a certain range of numbers are valid so that we can keep track of study participants, and make sure that they type in the actual ID number that is given to them. This is great, but it would be better to make each valid answer for that question (a participant's ID number) valid for only one use. For example, if someone enters the ID number "304", it is only valid for that first use so that if someone else tries to type in "304" it is no longer valid. Is there any way to do this?

You will require a web service which will authenticate the entered text ID on the fly i.e. once they enter and let them know if they can use.
