Counts in a list

Hi Jane

I'm assuming that you mean the top 30 most common/repeated postcodes.

The easiest way to identify them is to make a pivot table with the Postcode in both the ROWS and VALUES section.

Ensure the values is set to COUNT

This will display all postcodes and the number of times it has been repeated. You can then sort/filter the results to identify the values you want.
