Understanding Plus Codes and Open Location Codes
Plus Codes, also known as Open Location Codes (OLC), represent one of the most innovative advancements in global addressing since the invention of postal codes. Developed by Google and released as an open-source project under the Apache 2.0 license, Plus Codes provide a universal method for identifying any location on Earth using a short, memorable alphanumeric string. Unlike traditional street addresses that depend on named roads and numbered buildings, Plus Codes derive directly from latitude and longitude coordinates, making them accessible anywhere — from bustling metropolitan centers to remote rural villages without formal addressing infrastructure.
What makes Plus Codes truly remarkable is their simplicity and precision. A standard 10-digit Plus Code, such as 87G7MXQ9+7G, identifies a 14 by 14 meter area — roughly the size of a small building. This level of accuracy is sufficient for most everyday applications including delivery services, emergency response, and personal navigation. For scenarios requiring even greater precision, extending the code to 11 digits narrows the area to approximately 3.5 by 3.5 meters, while 14-digit codes achieve centimeter-level accuracy suitable for surveying and construction purposes.
The structure of a Plus Code follows a logical hierarchy. The first four characters form the area code, defining a 1-degree by 1-degree region (approximately 111 km by 111 km at the equator). The subsequent six characters constitute the local code, progressively narrowing the location through a base-20 grid system. The optional '+' separator, placed after the eighth character, serves as a visual delimiter and helps distinguish Plus Codes from other alphanumeric systems. This hierarchical design means that locations near each other share similar code prefixes, making the system intuitive for human use.
How do you convert a Plus Code to latitude and longitude? The process involves mathematical decoding of the base-20 grid system. Each character pair alternates between latitude and longitude refinements. For example, decoding 87G7MXQ9+7G reveals coordinates at approximately 40.7128°N, 74.0060°W — the heart of New York City. Our Plus Code converter performs this computation instantly in your browser, requiring no internet connection or external API calls. Simply paste your code, click convert, and receive precise coordinates along with accuracy metrics and an interactive map preview.
Real-world applications of Plus Codes are expanding rapidly. In India, NGOs like Shelter Associates have used Plus Codes to bring delivery services to slum areas for the first time. The International Rescue Committee employs them in Somalia for immunization tracking and family planning programs. In Cape Verde, unnamed streets across the archipelago are now navigable thanks to Plus Code addressing. Even in developed nations, Plus Codes solve the "last mile" problem for e-commerce deliveries to new construction sites, parks, and event venues lacking traditional addresses.
Our Plus Code to Latitude Longitude converter supports both full and short codes, batch processing for large datasets, and reverse conversion from coordinates back to Plus Codes. Whether you are a developer integrating geolocation into your application, a logistics coordinator managing delivery routes, or a researcher mapping remote field sites, this tool provides the accuracy and efficiency you need. The entire conversion process runs client-side, ensuring your location data remains private and secure. No data is transmitted to our servers or any third party.
Understanding the relationship between Plus Codes and traditional coordinate systems is essential for modern geospatial work. While latitude and longitude provide universal reference points, they are cumbersome to communicate — imagine reading "40.712776 degrees North, 74.005974 degrees West" over the phone. Plus Codes compress this information into 87G7MXQ9+7G, a format as easy to share as a phone number. Combined with our free converter, you can seamlessly move between these coordinate representations, unlocking the full potential of location-based services in your projects.
