There are a few public data sets that are immensely useful for developers, collected by the government, and should be much easier to locate than they are. Here are as close as I have been able to find to definitive lists:
US Zip Codescensus.gov (viz., ZCTA listing)
US Area Codesnanpa.com (viz., all states utilized codes listing)
US College and University Codesfau.eduIt would be nice if the government kept master data files on this information that they made free and open for download -- if not a public database with open API!
Perhaps organizing this into a public database could be the next phase of the
databug project.
