The National Do Not Call List (DNCL) was introduced in 2008 with the purpose of reducing unwanted telemarketing calls to those with phone numbers on the list. 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 (not deleted) with an indicator placed in a new field added to your record. A summary report provides you with statistical data describing your results and a record layout defines field positioning and content.

Please 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. After your are registered and subscribed we require your Registration Access Number, Subscription Access Number, and Download Key in order to process your file. Unfortunately, we cannot offer DNCL scrubbing without these numbers.
