Typically, the new data file became available to the public on Jan. 15, April 15, July 15 and Oct. 15, explains the CMS. Each time the file updated, the CMS considered it a replacement file, not an updated file.

The data format was text, and the file size was approximately 170 MB. Compatible software programs included Microsoft Access, Microsoft SQL/DB2/Oracle, SAS or other statistical software. The file cost was $100, according to the CMS. The final update of 2007 in the second quarter is available as of 2015. In June 2007, the CMS discontinued the UPIN and replaced it with the National Provider Identifier.
