Plus Code decoder
The center and area of a Plus Code; a short code needs a nearby reference point to recover the full code.
The code's center is 47.3655625°, 8.5249375°.

How we got thisFormula, worked example, sources, and proof
Model: Open Location Code decode; short codes recovered to the nearest match to the reference
Accuracy: Exact
When to use this: Use this when a Plus Code arrives as an address: it returns the center and the area of the code's cell. A short code, the form written with a town name, needs a nearby reference point before it can be recovered, and this takes one. It is what turns an address written as a code into coordinates you can navigate to, map, or compare against another position.
Limitations: The code names a cell, not a point: the common ten-character form is about fourteen meters square, and a shorter one is much larger. A short code without a reference point is ambiguous, and giving the wrong reference recovers a different place entirely, which is a real risk when the town name is dropped. Codes of different lengths mean very different areas, from a degree at four characters to a few meters at eleven, and a code with a plus sign in an unexpected place is invalid rather than approximate.

Changes
- 2026-09-19, changed: Every indexing tool is now stable. Geohash decode and neighbors match pygeohash on 1,000 and 500 cases; the Plus Code tools pass every row of the Open Location Code test data; tile ground resolution matches the Bing Maps table; the H3 resolution chooser matches H3's resolution table; and H3 polygon fill gives H3 C's own test counts (1,253 cells, 1,214 with a hole). Results are unchanged apart from the fix below. Changelog
Checked against: 49 golden test vectors (download the test vectors, each with its source and tolerance). See how results are checked and every source.
