Why number your house? A paper
published by Cambridge University argues that house numbers are more than just ways to make the post office’s job easier. House numbers facilitated huge a range of activities, from census-taking, to military enlistment, to law enforcement. House numbers
became less political and more utilitarian over the years. Numbered houses are an easy way to give a place a unique identifier, making life easier for emergency services workers, your visitors, and commercial interests alike.
