Martha (the OP), indicated she had the answer at the same time
you replied, evidently just new entries are the problem.

If there were a number of old entries you would want to convert
them to text, and I have a macro for that.

Tom, a zip code of 7234 formatted as 00000 to show 07234
would test as a length of 4 =LEN(A1)

Nine digit zip codes do not sort properly in Excel even when the cell is

use 9 digit zipcodes because of the error. Help!

Can you give an example of improperly sorted 9 digit zip codes? Although I
think I know what you mean, I was not able to replicate a sorting error.
