DNC (Do Not Call) suppression checking

Optimise your calling campaigns and reduce any complaints that you may receive.

What is a DNC check?


We have a database of approximately 2 million numbers from individuals who have expressed that they do not wish to be called for marketing purposes. This database is made up of individuals who have contacted us directly, as well as those that have contacted our partners.

Why is DNC screening important?

Whilst these individuals have said they do not wish to be called for marketing purposes, they may not have registered with the TPS or the CTPS as yet.

By screening your data against the DNC list, you can ensure that you are removing any possible complainants from your records.

How we screen your data

We screen your data automatically against the DNC list as part of our TPS/CTPS screening service, to enable you to easily identify these individuals and remove them from your calling lists if you so wish.

Though, unless someone has specifically asked to be removed from your calling list, or registered with the TPS, you don’t have to remove them, we find it is best practice to remove all of the individuals who have expressed they don’t want to be called, as this reduces down any complaints that your staff may have to handle.
