1. Introduction

The Worldwide Coordinate Identifier (WWC-ID) is an open, decentralized encoding system that uniquely describes almost any point on Earth. Each location receives a 9-character alphanumeric identifier, which is fully mathematically defined, reversible, offline computable, and freely licensed.

The WWC-ID is suitable for navigation, humanitarian work, documentation, research, crisis response, and any application that requires a permanent and universal location identification system.

1.1 Historical Context

The term World Wide Code (WWC) was first published on 17 March 2009 by Rüdiger Gums. The original concept appeared simultaneously in several language editions:

German:
“World Wide Code (WWC): Die neue Orientierung”
ISBN-10: 3941756001
ISBN-13: 978-3941756007

English:
“World Wide Code (WWC): The New Orientation”
ISBN-10: 3-941756-01-X
ISBN-13: 978-3-941756-01-4

French:
“World Wide Code (WWC): La nouvelle orientation”
ISBN-10: 3-941756-02-8
ISBN-13: 978-3-941756-02-1

Albanian:
“World Wide Code (WWC): Ky orientim i ri”
ISBN-10: 3-941756-03-6
ISBN-13: 978-3-941756-03-8

Spanish:
“World Wide Code (WWC): La nueva orientación”
ISBN-10: 3-941756-04-4
ISBN-13: 978-3-941756-04-5

These publications from 2009 serve exclusively as a historical reference and document the first use of the term World Wide Code (WWC).

The WWC-ID Specification (2025), by contrast, is a completely newly defined, mathematically reproducible and MIT-licensed system for uniquely encoding geographic locations. The historical term WWC is not part of the modern WWC-ID specification. WWC-ID is an independent, contemporary, and technically distinct system.
