New movers are big spenders who are changing things up. We can connect you with all of them

ResponseCanada Pre-Movers / Movers is Canada’s biggest and most accurate compilation of Canadian households on the move. Cleanlist meticulously tracks every Canadian home that’s listed for sale, then follows it through the move process. Each record is cleaned, standardized and enriched in ways that only Cleanlist can do – complete with in-depth profiles to allow for precision targeting and personalized messaging. For many organizations, this is a gold-mine just waiting to be tapped.

Postal Code Targeting might just be the silver bullet you've always wanted

Identity and life verification just got a whole lot faster and easier

  • Protect your
  • Fight back
    against fraud
  • Comply with KYC

Does an end-of-life event expose your organization to risk?

Deceased Identification is a Cleanlist-exclusive life verification solution that can inform you of deceased customers, accounts, or policyholders quickly and precisely. More than 250,000 Canadians die annually. Yet many of them remain on databases for months and even years.

The old ways of life verification required extensive sampling and the mailing of cumbersome proof-of-life forms. These processes are expensive to execute and very slow to work. Thankfully, there’s a much better way.

Cleanlist helped create the Canadian Deceased Registry – the only commercially available record of deceased Canadians. It’s updated daily, directly from Canada’s 2,200 funeral homes. Coverage is broad and the data is highly accurate.

The Deceased Identification service securely monitors your accounts and alerts you to deaths the moment they occur. Plus, you’ll get access to an online tool to verify the data and confirm the death. No other solution is as timely, easy-to-use, and effective.

Occupancy verification is just an API call away

Right Party Verification is a Cleanlist-exclusive occupancy verification solution that helps you confirm that someone lives where you think they do. It’s used as part of Know-Your-Customer (KYC) compliance programs, to help reduce fraud, and to clean and validate large databases.

Maybe you’ve been out of touch for a while, and want to confirm your addresses. Or, possibly you need to be extra sure something important or expensive gets there. In many cases, our clients use Right Party Verification as part of their account onboarding and KYC program. For all these situations and more, Right Party Verification can help you save costs, prevent fraud, and invest with certainty.
