Matching First and second names with ID numbers

Hi

I am new but really need help. I need to match a list of names with there ID number. The list of names is small only about 200 but the ID is is about 6000.

The fist list has a First and second name a Post Code(zip code) and other bit's of information that I need to have the ID to be able to imput it but it doesn't have that ID number

The list of ID's has First and second name a Post Code(zip code) and the ID code but dosn't have the information on it that I need.

My question is - is there a script I can use that will match the First and second name and post on the ID list and then move the ID code onto a separate column?

Thanks!
