The 2014 Postal Code Conversion File (enhanced by Environics Analytics) is now available in the catalogue. For those not familiar with the PCCF, it allows you to map each six-digit postal code with a latitude/longitude coordinate. It also tells you which census geographies each postal code falls into. (Just be careful doing so with dissemination areas and census subdivisions: their boundaries don't coincide very well with postal codes.)
If you need help using the PCCF, or merging it with other data, e.g. TransUnion or Taxfiler, don't hesitate to ask us for pointers.
