To answer your question, as of right now there is not a specific number applied to each line. 99% of the time though the combination of columns A, B, C should always produce a unique identifier. I'm assuming then that I would need to add another column prior to A and change all the code so that anything that was Column A is now B and so forth. The other problem with adding anymore information is the page size. Another column will push the page limit and it would have to be printed in landscape mode. Would it be possible to create another column but leave it hidden so that is not printed or displayed but continue to be used for information.

The other problem would be that unique number would be required to be added to each line unless it would be possible to add each number as the information is entered or pasted into the worksheet.
