The Address on the Envelope: Streets, House Numbers, Postal Codes and How the World Learned Where Everyone Lives

Every home has an address. But who decided what that address should be?

Street names, house numbers and postal codes are so familiar that most people rarely question them. Yet behind every address lies a remarkable history of growing cities, expanding empires, government records, postal networks and the human need to find places beyond our immediate surroundings.

The Address on the Envelope explores how the world learned to identify individual buildings and why something as ordinary as a street number became essential to modern life.

From the first organised numbering systems in European cities to Britain's postcodes, America's ZIP Codes and the distinctive addressing traditions of Japan and other countries, Marcus Ellery reveals how societies developed different solutions to the same geographical problem.

The book also examines rural homes without numbered streets, settlements missing from official records, emergency services searching for the correct doorway, and the digital mapping technologies transforming how we locate places today.

Accessible, informative and international in scope, this is a fascinating exploration of the hidden systems that connect people, buildings and communities.

Every address tells us where something is. Its history reveals how the world learned to find it.
