I have column A with over 500 account numbers. What is the formula that will
allow me to see which of those accounts are listed more than once.

One way:
1) Sort the column in ascending order
2) In B2 enter a formula: =IF(A2=A1,1,"") and fill down to the bottom of
your column of numbers in column A
3) Anywhere where a 1 appears, there are duplicates.
