Corporate Telephone Preference Service from Data Soap

Data Soap screens against the TPS, CTPS and a Do Not Call suppression list of approximately 2 million numbers in one clean. We aim to return your cleaned data in one working day to give you a hand in your battle for reducing the amount of complaints.

What is CTPS?

The Corporate Telephone Preference Service (CTPS) is an opt out register for corporate subscribers who express their wish not to receive unsolicited sales and marketing calls to their numbers. It is a legal requirement that companies do not make calls to numbers registered on the CTPS unless they have the express opt-in permission to do so. The CTPS differs from the TPS for residential consumers in that you need to renew the registration with the site every year.
