They are not the only ones doing the sorting though, with Norwich Evening News community content curator Kate Wolstenholme looking through the archives to find these pictures of festive postal workers through the years.
Looking back at the pictures it seems not a lot has changed from the oldest to most recent images, with letters still making the trip down a chute before being collected by a postal worker at the bottom.
Other areas of the office also seem remarkably unchanged, with the only thing difference being the people.
