Telemarketers will be able to download the National DNCL in two different file formats:

Comma-separated Value (CSV) format, also known as a “Flat Text File”; and
Extensible Markup Language (XML) Tagged File.
The files will be provided for downloading in one Zip file, which includes individual files for each Canadian NPA (area code) selected. If the full national list is selected, then one Zip file will be provided containing a single file with all numbers registered on the National DNCL for Canada.
