Postal Code Conversion File [Canada], March 2024, Census of Canada 2021

The Postal Code Conversion File (PCCF) is a digital file which provides a correspondence between the Canada Post Corporation (CPC) six-character postal code and Statistics Canada's standard geographic areas for which census data and other statistics are produced. Through the link between postal codes and standard geographic areas, the PCCF permits the integration of data from various sources. The Single Link Indicator provides one best link for every postal code, as there are multiple records for many postal codes. To obtain the postal code conversion file or for questions, consult the DLI contact at your educational institution. New to the June 2022 version, a separate data file is available for retired postal codes. The retired file uses the same record layout as the PCCF file. The same syntax file can be used for both the PCCF data file and the retired data file. The geographic coordinates attached to each postal code on the PCCF are commonly used to map the distribution of data for spatial analysis (e.g., clients, activities). The location information is a powerful tool for planning, or research purposes. In April 1983, the Statistical Registers and Geography Division released the first version of the PCCF, which linked postal codesOM to 1981 Census geographic areas and included geographic coordinates. Since then, the file has been updated on a regular basis to reflect changes. For this release of the PCCF, the postal codes are directly geocoded to 2021 Census geographic areas. A quality indicator for the confidence of this linkage is available in the PCCF.邮政编码转换文件（Postal Code Conversion File，PCCF）是一种数字文件，用于建立加拿大邮政公司（Canada Post Corporation，CPC）的6位字符邮政编码与加拿大统计局（Statistics Canada）标准地理区域之间的对应关系——这些标准地理区域正是生成普查数据及其他统计数据的依据。通过邮政编码与标准地理区域之间的关联，该文件可实现多源数据的整合。单链接指示器（Single Link Indicator）可为每个邮政编码生成一条最优关联记录，由于多数邮政编码对应多条原始记录。如需获取该邮政编码转换文件或有相关疑问，请联系您所在教育机构的DLI联络人。2022年6月版新增了针对已退役邮政编码的独立数据文件，该退役文件与PCCF文件采用相同的记录格式，二者可共用同一语法文件。PCCF中附加于每个邮政编码的地理坐标，常被用于绘制数据分布地图以开展空间分析（如客户分布、活动分布分析），此类位置信息可作为规划与研究工作的有力工具。1983年4月，加拿大统计局统计登记与地理处发布了首个版本的PCCF，该版本将邮政编码与1981年普查地理区域进行关联，并附带地理坐标信息。自此之后，该文件会定期更新以适配各类变更。在本次发布的PCCF版本中，邮政编码已直接地理编码至2021年普查地理区域。PCCF中还提供了用于评估该关联置信度的质量指示器。
