Files on postal coding in the Norwich area, May 1959
Finding number: POST 122/1137
This confidential document discusses the introduction of post codes in the Norwich area and testing the public reaction to them. It is part of a block of records that looks at how many people used postcodes on their letters during the experiment. For a time, about a third of all letters had the experimental codes on.
There are indicators of how well automated sorting machinery might cope with the different kinds of codes considered, as well as detail relating to the workings of the trial on the ground.
Given the impact that postcodes now have on the lives of all UK residents, the way they affect prices paid for insurance, the delivery of healthcare and so on, the creation of these codes is clearly a significant development.
