Charities and other interested organisations are being invited to give their views on new rules that would allow people to enter society lotteries by text.
The consultation will ask about proposed new rules designed to ensure that lottery operators prevent anyone under the age of 16 from being able to enter lotteries by text, provide clear information about how to claim winnings and offer access to gambling addiction support.
The consultation comes after a new category of VAT-exempt short phone number was set up for society lotteries, which means that people wishing to enter lotteries by text can send their entries to a number beginning 72.
General text donations to charity are made by sending a message to numbers beginning 70, and the PSA estimates this raised £110m for charities last year.
A PSA spokesman said: "We’re pleased to see further growth and innovation in this space, and we hope that these special conditions will help to build consumer confidence in these services.
"Effective regulation can play an important part in building and maintaining a secure and dynamic market where consumers can charge content, goods and services to their phone bills with confidence.
"We look forward to hearing from people in the phone-paid services industry and the charity sector."
