In the summer of 1940, a young soldier from Surrey, England, named D.J. Page stumbled upon an astonishing coincidence in a letter. Inside the envelope was a photo of him from his recent wedding, but it had been mistakenly opened by another soldier from a different unit. The soldier's name was Pep, and his number was 1509322, while Page's number was 1509321. The striking similarity between their names and numbers often led to confusion with their mail. This issue was only resolved when Page was transferred to another artillery unit.

After the war, Page became a driver for the London Transport Department. During one pay period, he noticed an unusually high tax deduction and went to speak with his supervisor for clarification. To his surprise, he found out that his salary had been mistakenly mixed up with that of another driver named Pep. Page was astounded to learn that this Pep was the same soldier who had opened his letter earlier. Even more incredible was the fact that Page's driving license number was 29222, while Pep's was 29223, nearly identical.
