The Corporate Telephone Preference Service (CTPS)

The Corporate Telephone Preference Service (CTPS) register currently contains 1,330,716 numbers.

Below you will see details of the size of the CTPS register at the end of each month together with the number of monthly additions and removals.

The CTPS requires businesses to re-register their number every year which is why you can often see large quantities of numbers coming off the register unlike the Telephone Preference Services (TPS) register which does not require consumers to re-register at any point.
