National Do Not Call List (DNCL)

Identify prospects registered on the National Do Not Call List.

The National Do Not Call List (DNCL) was introduced in 2008 by Canada's CRTC with the objective of reducing unwanted telemarketing calls to consumers who register their number on the database. While there are a few exceptions, many telemarketing firms are required by law to comply with the DNCL, or face large financial penalties issued by the CRTC (up to $1,500 per violation for individuals and up to $15,000 per violation for businesses).

By removing prospects registered on the National DNCL your firm can become compliant with the DNCL and avoid potentially damaging financial penalties.

Matched records are flagged.

A summary report provides you with statistical data describing your results and a record layout defines field positioning and content.

For more information on the National DNCL, please visit our Canadian National Do Not Call List FAQ.

Note: In order for Cleanlist to flag your records with those registered on the National DNCL, your organization is required by the CRTC to be both registered and subscribed to the National DNCL. Once you're registered and have purchased a subscription, Cleanlist requires your Registration Access Number, Subscription Access Number, and Download Key in order to process your file. Unfortunately, the CRTC does not permit Cleanlist to offer DNCL scrubbing without our clients being directly registered with the CRTC and having an active DNCL subscription.

An included summary report provides statistical data describing your results.


  1. Comply with CRTC policy and avoid large CTRC-issued financial penalties.
  2. Improve response rates and reduce costs by not contacting non-responsive individuals.
