VLOOKUP returns incorrect results when comparing zip codes across worksheets. I think the problem could be caused by 2 things:
1. There are duplicate rows in the lookup_value range because each represents an individual and needs to remain a duplicate to show whether there are multiple individuals from the same zip. In these cases, VLOOKUP only returns the first matching zip from rows containing duplicate zips. (See 07042 in worksheet 1 of the file linked below.)
2. Zip code format is not being treated as a number during sort. Do I need to use a different format during sort? Don't want to lose the leading zeros on the zips.

How can I make VLOOKUP work correctly in this context? Thanks!
