The Telephone Preference Service will conduct research into how charities use mobile phones for fundraising before launching two new opt-out registers.
The TPS, a free register of people who do not want to receive marketing or fundraising calls, is planning to introduce a separate list for mobile phones and another service allowing parents to register their children's mobile numbers.
Colin Lloyd, chair of the TPS, told Third Sector that the organisation would carry out research in the new year to find out how charities use mobile phones for fundraising before launching the new lists later in 2011.
More than 16 million of the 24 million households in the UK are registered with the TPS. Mobile phones are the fastest-growing area, with a million registered numbers on the existing list.
Lloyd said the need for a separate mobile register was driven by the falling cost of mobile phone calls, which made it cheaper for organisations to make marketing calls to consumers. The new system will save charities that want to send out SMS appeals from the time-consuming process of separating mobile numbers from landlines on the list, he said.
