The UK trading watchdog is asking the public to collect any potential scam mailings they have recently received and drop them into designated 'Scamnesty' bins or boxes at areas across the country.
The campaign is part of 'scams awareness month', a nationwide drive to reduce the £3.5 billion cost of scams in the UK every year.
The Office of Fair Trading (OFT) wants to raise awareness of mass marketed scams that affect three million people a year such as bogus lotteries, deceptive prize draws and sweepstakes, fake psychics, get-rich-quick schemes and miracle health cures.
However, OFT research suggests that less than five per cent of victims report the incident to the authorities.
The mailings collected from the 'Scamnesty' bins could provide crucial intelligence to prevent others from being scammed, according to the OFT.
Mike Haley, OFT director of consumer protection, said: "Any scam mailings that are dropped in the bins could be vital in gathering intelligence on the latest scams and in stopping the worst offenders from continuing to bring misery to thousands of vulnerable people each year."
