V-LOOK UP FORMULA

I am working with 2 excel workbooks. I am copying the company i.d. # in one and pasting it in the right cell in the other. I was wondering if it was possible to create some type of logic formula to do the work for me. In each workbook there is a column for company name, address, city, zipcode and state. Is it possible to make a formula that maybe says, 'if this address # and city in workbook 1 matches this address # and city in workbook 2, then copy and paste this company i.d. # from workbook 2 into this cell in workbook 1.'

Thanks,
J

vlookup

create a new column combining the 2 you want to lookup on.
so the column values look like: "London Road London"
then vlookup on that..
e.g. to combine columns a and b, column c has the formula: =A1&B1 in cell c1. Copy this down.
