Traditional street addresses fail more often than you'd expect. If you're trying to direct a courier to a specific park entrance, locate a building in a dense metropolitan labyrinth, or find a rural home without a formal street name, standard postal data falls short. To bridge this gap, Google developed Plus Codes—an open-source location addressing system built on latitude and longitude coordinates. When paired with a local city name, a short 6 digit code pinpoints locations with remarkable precision, transforming how delivery drivers, emergency responders, and everyday users navigate the physical world.
Understanding how these alphanumeric strings work helps you share your exact position without relying on complicated GPS coordinates or ambiguous street names. Whether you're integrating open location tech into a logistics workflow or just trying to help friends find a remote campsite, mastering this system eliminates the friction of traditional navigation.
What Are Google Plus Codes and How Do They Work?
At its core, a Plus Code (formally known as an Open Location Code) is a alphanumeric grid reference derived directly from a location's latitude and longitude. Instead of showing a long, error-prone string of decimal degrees like 37.422000, -122.084000, the system translates those coordinates into a short sequence of numbers and letters.
The global mapping grid breaks the Earth down into a series of hierarchical rectangles:
- Large grids: The first few characters define a wide region (roughly 100 by 100 degrees).
- Medium grids: Subsequent characters narrow the position down to city or neighborhood blocks.
- High precision: The final characters shrink the target area down to small zones—often roughly 14 by 14 meters for standard codes, or even smaller with additional characters.
Because they rely strictly on geometric coordinates rather than government-issued postal registries, these codes cover every square inch of the planet, including open oceans, deserts, and informal settlements lacking formal street infrastructure. You can learn more about the technical specification through the Google Maps Plus Codes Guide.
The Role of the 6-Digit Key in Local Navigation
Full global Plus Codes typically span ten to eleven characters (plus a separator symbol like +), such as 87G7MXQ4+P5. While highly accurate, a ten-character code can be cumbersome to read aloud over the phone.
To solve this, Google introduced abbreviated Plus Codes. By replacing the first four characters—the wide-area regional prefix—with a local city name, the code condenses down to a 6-digit format plus the separator (for example, MXQ4+P5 New York).
This 6-digit local key provides several distinct advantages:
- Memorability: A shorter code acts much like a local telephone number, making it easy to dictate or remember quickly.
- Contextual Accuracy: When combined with a municipality name, it locks in the correct regional grid without forcing the user to transmit global coordinates.
- Hyper-Local Precision: It narrows search parameters down to a tight geographic box, ensuring couriers arrive at the correct loading dock or side entrance rather than the middle of a large block.

How to Find and Use Plus Codes in Google Maps
Finding and sharing a code on your mobile device or desktop requires just a few taps. The system is built directly into mapping software, requiring no third-party downloads.
- Open Google Maps on your phone or browser.
- Drop a pin on any exact location, or tap an existing business, landmark, or home.
- Scroll down the bottom information sheet to view the location details.
- Look for the Plus Code entry (displayed as a mix of letters and numbers with a plus sign, like
7JVW+52). - Copy the code and paste it directly into the Google Maps search bar to instantly jump to that exact spot.
If you're sharing the code with someone already in your city, you can use the shortened 6-digit local variant alongside your city name. If you're coordinating across international borders, always provide the full global code.
Common Mistakes to Avoid
While location codes simplify navigation, users often run into a few predictable pitfalls:
- Dropping the city context with 6-digit codes: Never text a raw 6-digit code to someone in a different city. Without the local town name or regional prefix, the code becomes completely ambiguous because identical 6-digit sequences repeat globally.
- Confusing similar characters: Hand-copying codes can lead to errors. The coding alphabet intentionally excludes certain easily confused vowels and letters (like 'I' and 'O') to minimize typos, but care is still required when reading handwritten notes.
- Ignoring entrance-specific tags: Dropping a pin on the middle of a large commercial building gives you a general code. If you need a specific delivery bay or pedestrian gate, zoom in closely and drop your pin directly on that entrance before copying the code.
Frequently Asked Questions
Do Plus Codes require an active internet connection to work?
Yes and no. Generating or decoding codes programmatically relies on mathematical formulas derived from latitude and longitude, meaning the underlying logic works offline. However, looking up a code's physical location or translating a 6-digit local code using a city name inside Google Maps requires data connectivity to load the map tiles and municipal boundaries.
Are Plus Codes compatible with navigation apps other than Google Maps?
Yes. Because Plus Codes are based on the open-source Open Location Code standard, other mapping platforms and open-source navigation tools can encode and decode them. You aren't locked into a single proprietary ecosystem.
How large is the target area for a standard 10-digit code?
A standard full code maps out a grid cell roughly 14 by 14 meters in size. This is precise enough to isolate individual residential properties, specific storefronts, or distinct building wings.
Can businesses register their Plus Codes officially?
Businesses don't need to "register" a code because codes are algorithmically generated from geographic coordinates. However, adding your location's Plus Code to your website, contact page, and delivery instructions helps logistics drivers find your exact entrance instantly.
