Every cell in Column A starting in row 2 is filled

You can try this but if the above is literally true, this may not be such a
good idea!

Entered in B2 and copied down as needed.

=COUNTIF(A$2:A2,A2)

Every cell in Column A starting in row 2 is filled with seven digit
numbers.
Often times each seven digit number will occur more than once. I want to
put a formula in every cell in Column B starting in row 2 so that if I
have a
seven digit number that appears for the first time in cell A5 a "1" will
appear next to it in B5. If that same seven digit number appears in cell
A25
a "2" will appear next to it in cell B25. Finally if that same number
appears in cell A39 then a "3" will appear next to it in cell B39.
However
the numbers won't always appear in A5, B25, or B39. Those were random
cells
that I selected. Is this possible or do I need a macro to do this?
