If you'd like to include companies with two sets of zip codes (that exclude companies with some zip codes), we recommend you use a combination of segments.
For example, let's say you wanted to include companies with these zip codes: 122 40 through 122 50 and 133 10 through 133 40 and you wanted to exclude companies with zip codes 122 51 through 133 09.
First create Segment A, where you include companies with zip code 122 40 through 122 50.
Then create Segment B, where you include companies with zip code 133 10 through 133 40.
In Segment B, you also include Segment A.
