Telephone Preference Service Screening - TPS Checker

121prodata is your organisation's answer to TPS compliance and provides easy, fast and low cost TPS checking.

Our TPS screening services enable you to be legally compliant and to save time and money. 

121prodata is a full TPS and CTPS licensee and our register data is updated daily. 

If you are making sales and marketing calls to UK individuals or organisations, you are now required by law to check every 28 days and remove from unsolicited calling all telephone numbers registered with TPS and CTPS (Corporate TPS) to ‘opt-out’ from receiving calls.

If you're not sure about your legal obligations - take a quick look at our short guide - 'Staying within the law when making sales and marketing calls'.



3 Ways to TPS Check your Telephone Numbers


“121prodata’s online TPS screening is very easy to use, even for a non-techie. I would definitely recommend it to sales and marketing execs looking to screen data quickly and at low cost.  The beauty of it is that you can do-it-yourself and don’t need to wait for a data bureau to come back to you”. 

Frankie Mortimore, Marketing Account Manager, EEIDB Ltd



“Exemplas asks 121prodata to correct, prepare and screen more than 420,000 numbers every 28 days. It’s an excellent service and the people are helpful too – which is always a good sign. They’ve also set up a secure FTP for us to transfer data to and from them, which helps us meet data security requirements”.

Amy Duffin, DBA, Exemplas
