I’m writing to see about getting older versions of the PCCF (Postal Code Conversion File). The DLI FTP site has files from 2007 to March of 2008, but nothing older. I have locally stored files from earlier years, but lack 2004 through 2006. A researcher here needs a version of the PCCF from this period. Are these older files still available? Is there a reason why we don’t have these older files on the DLI FTP site?
Older versions of the PCCF are available on our FTP site. The PCCFs for 2002 to 2006 are available in the 2001 folder:
More PCCF files can be found in the 1986, 1991, and 1996 folders at: /ftp/dli/geography
