PCCF + version 5D user's guide : automated geographic coding based on the Statistics Canada postal code conversion files including postal codes through September 2008 / by Russell Wilkins. : CS82-0086/2009E-PDF

"PCCF + Version 5 consists of a SAS control program and a series of reference files derived from the most recent Statistics Canada Postal Code Conversion File (PCCF) and a 2006 postal code population weight file (WCF). It automatically assigns a full range of geographic identifiers (down to dissemination area, dissemination block, and latitude, longitude) based on postal codes. It is consistent and logical in the way it does this. Any incorrect coding due to errors in the underlying reference files can easily be corrected once identified. To do such coding by manual methods would require highly skilled coders with much time and access to the full mailing address or property description. Even so, the results of manual coding would tend to be less accurate (particularly in urban areas), and they could inadvertently introduce systematic bias (especially in rural areas)"--Abstract.
