• NPPES Data Dissemination (May 14, 2013) - ZIP format (436 MB)

Beginning with the May 2008 file, the size of the .csv Header File increased because we added Authorized Official data elements to it that were inadvertently not previously included. As a result of the larger size, the .csv Header File can no longer be opened in Excel. Even so, the .csv Header File is small enough to be opened by a simple text editor like Notepad. As always, the .csv data file must be opened with a text editor capable of opening large files. Two examples are TextPad and UltraEdit.
