I know there’s a much more complex (and correct) answer than this, but ZIP codes aren’t 1:1 with cities. My city is a suburban one but has something like a dozen ZIP codes. They provide additional granularity and help route mail more efficiently, though leaving a ZIP code off of your mail will still result in your mail being delivered.
