My guess is that they may fall back to zip if they are missing something or something doesn't add up. Also, the birthdate might be pulling from a different source than the mosaic data - probably what you entered in DL.com. The mosaic data is pulled by your address, I suspect. Data that delta collects is not necessarily used as an input to get the mosaic code.
