Top community discussions about FourOneOne

FourOneOne is a small application that allows you to look up airport codes, area codes, country codes and ZIP codes. It was inspired by the (now discontinued) Code Finder application by Andrew Zamler-Carhart.

The data comes from freely available files published by the OpenBSD and NetBSD projects.

What's New in FourOneOne

Version 1.0.1:
  • Now uses an internal copy of the data by default (this can be changed in Preferences). This should fix problems that some users had when running with older data files.
