Hi,

In 2007 - combine all the list by copy/paste below each other. Then choose
the command Data, Remove Duplicates....

In 2003 - combine all the list by copy/paste below each other. Select just
the column with the repeat numbers and then choose Data, Filter, Advanced
filter, Copy to another location, make sure the list range is just your
number column with a single title at the top, no Criteria range, the first
cell of a blank column for the Copy to range, lets say D1. Check Unique
records only and then OK.
Now build VLOOKUP functions to retrieve any other columns of data you want.

You could also use a VBA macro.
