The DMTI Six Digit Postal Code file that we have is from 2002 onward. Does any one know if Six Digit Postal Code data is available for 1998 - 2002 from Geography or another source?
Answer
The Geography Division did not create a product that contained representative points for postal codes. There are representative point coordinates contained in the PCCF products,
but they are the coordinates for the representative points of the census geography that is the best fit for that postal code and not for the postal code itself.
The PCCF has latitude/longitude for all postal codes – since it contains all postal code records, it’s possible to use that file to create a list of valid postal codes for 1998, and to determine the lat/long of each 6-digit postal code. It won’t be exact – but it will be better than nothing.
