Suppose these are in A1:A1000
Insert a new row 1 and in A1 type a label (could be just the word ZIP)
Select all of the occupied A cells; use Data | Advanced Filter and specify
Unique
Now you have a list of the zips; copy these to A1 of Sheet 2
Select the data in A of Sheet1 again and use Data | Advanced Filter and
specify show all
In B1 of Sheet 2 use =COUNTIF(Sheet1!A:A,Sheet2!A1)
Copy this don the column
