BGRID
Address the World with Precision
From global to local, find any point on Earth using a memorable sequence of words.
Hierarchical Precision
BGrid divides the world into 2048 distinct regions at every level.
Try hovering over the grid above. In a real BGrid, each cell resolves to a BIP39 word.
Row-Major Cell Indexing
Each level subdivides a region into a 64×32 or 32×64 grid, yielding exactly 2048 cells per level. Cells are indexed in row-major order (raster scan): starting at the top-left corner, numbering proceeds left-to-right across each row, then continues on the next row below.
Arrows indicate the scan direction. Corners show the first and last cell index of each visible row.
The index can be computed with either formula — both are equivalent, depending on whether rows and columns start at 0 or 1:
- 0-based:
row × cols + col + 1 - 1-based:
(row − 1) × cols + col
producing a contiguous sequence from 1 to 2048.
Can help in Emergencies
In critical situations, every second counts. BGrid addresses make location sharing fast and reliable when it matters most.
Short sequences of common words that can be spoken clearly over radio or phone, even in noisy environments.
Each word maps to a number (1–2048), so addresses can be typed on any phone keypad without a smartphone.
Unlike GPS coordinates, there's nothing to spell out letter by letter — just say the words.
Available in 9 languages, so responders and victims can communicate locations in their native tongue.
No internet connection required — the grid is deterministic and can be resolved locally on any device.
Under stress, people recall common words far better than long numeric coordinates. Four words is all it takes.
