Please be advised that, effective January 1, 2014, Canada Post will no longer permit the distribution of the raw NCOA database outside of Canada. International mailers and service providers will still be able to process Canadian NCOA data; however, all processing will have to be done on Canadian soil. Mailers should contact their mail service provider to determine if and how they are impacted by these changes. Canada Post has been working with licensees since late 2012 to help them adapt to the changes and to mitigate any impact to mailers.
