No, that is the only identifier available.

Is there another column that is fairly unique that you can sort by instead?
You can always resort the third workbook by ID later.

Hi,

Here is my situation. I have two workbooks whose information i have to
combine in to a third workbook. the data in all colums are different except
for the first column. the first column of each contains customers
identification numbers. for the third workbook i will be including ALL the
columns from the first two workbooks. my problem is this: the ID numbers
will not be in the same order in the first two workbooks. is there a way to
check the order in the first two workbooks and create one list in the third
workbook that is sorted. i guess the data in the other columns would have to
be sorted based on the ID number sort. does this make sense?

thank you in advance
