Britons send more greetings cards than consumers in any other country included in a survey by Ofcom.
As the final posting date for Christmas approaches, research by the communications regulator found that more than a third of UK adults (37%) had sent a greetings card, invitation or postcard in the last month - the highest rate in the world.
Australia is in second place at 34%.
Consumers in France were the least likely to send greetings cards with just 17% saying they had done so in the last month.
The findings, revealed in Ofcom's International Communications Market report, found 33% of people in China had sent a card in the last month, compared with the US (32%), Italy (30%), Germany (24%), Japan (23%) and Spain (19%).
Ofcom's director of research, James Thickett, said: "Although we're all increasingly using digital methods of communication, our research shows that the traditional greetings card still remains a popular choice for UK consumers."
Ofcom surveyed a total of 5,243 consumers in the UK, France, Germany, Italy, USA, Japan, Australia, Spain and China in September.
