I was looking through my received postcards today and decided to sort by Postcard ID. I discovered that in August 2017 I’d received DE-6425810 and DE-6425811. I don’t know what the odds are of two Postcrossers getting my address moments apart, but two from the same country must be unlikely (even allowing for the fact that it’s Germany ).
Does anyone else have consecutive Postcard IDs? Has anyone got a sequence of three?
