When I looked it up here is what I found and it says zero residents and we have never used this zipcode since I have been here almost 8 years. I think it is safe to delete it.

We use a third party service to provide address information, so we would expect this to be updated in that service if it's no longer a zip. Until then, we don't really have an easy way to control what zip codes show up or don't show up in that list.
