Postal Code Conversion File [Canada], September 2022, 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 vast majority of the postal codesOM are directly geocoded to 2016 Census geography while others are linked via various conversion processes. 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）是一类数字文件，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用于生成普查数据及其他统计数据的标准地理区域之间的对应关系。通过邮政编码与标准地理区域之间的关联，PCCF可实现多源数据的整合。由于多数邮政编码对应多条记录，单链接指示器（Single Link Indicator）会为每个邮政编码提供一条最优关联结果。如需获取该邮政编码转换文件或咨询相关问题，请联系您所在教育机构的DLI联络人。
2022年6月版本新增了一项更新：针对已停用的邮政编码，可单独获取一份专用数据文件。该停用邮政编码文件的记录布局与PCCF文件完全一致，二者可共用同一份语法文件。
PCCF中绑定至每个邮政编码的地理坐标，常被用于绘制空间分析所需的数据分布地图（例如客户分布、活动分布）。此类位置信息是支撑规划与研究工作的高效工具。
1983年4月，加拿大统计局统计登记与地理分部首次发布了PCCF的初始版本，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。自此之后，该文件会定期更新以适配地理信息变化。
在本次发布的PCCF版本中，绝大多数邮政编码已直接完成地理编码至2016年普查地理区域，其余邮政编码则通过各类转换流程完成关联。PCCF中还提供了用于衡量该关联置信度的质量指示器。
