Here at UKCrimeStats we spend a lot of time working on postcodes. Every few months, drugstore new postcodes are created, others are decommissioned and we then go away and do the radius calculations and all the matchings to different areas and of course crimes and property prices. So postcodes can get out of date very quickly and there’s nothing more annoying than missing a few postcodes out of a few thousand. That won’t happen with UKCrimeStats. We have also been careful to keep a record of the retired postcodes because many people unknowingly keep using them for years afterwards.
