A Great Yarmouth woman is warning people to be on alert to scammers posing as the Postcode Lottery.
The 79-year-old's suspicions were first aroused when a letter dropped on her doormat addressed to her dead husband.
It told her she had won £355,000 and that she just needed to call a number to collect her winnings.
Her fears about it being the work of con-men were confirmed when she called the real Postcode Lottery and now she is keen to encourage others to be on their guard.
'It all looks very authentic,' she said.
A spokesman for Norfolk County Council said: 'Lottery scams have done the rounds in various forms over many years, so this is nothing new.
'Our message is clear – if you haven't bought a lottery ticket then you can never be a winner.
'We would urge people to sign up for our Trading Standards scam alerts to receive information about the latest scams to look out for.'
