- geoMidpoint● ready
The true halfway point between two locations on the globe — not the naive average of the latitudes and longitudes.
- geoDestination● ready
Given a start point, a compass bearing, and a distance, compute where you end up on the globe.
- geoBearing● ready
Enter two points to get the heading you start on and the heading you arrive on — great circles curve, so they differ.
Validate & Format

Enter an IBAN to validate its format, check the MOD-97 checksum, identify the country and bank, and format it with proper spacing.
- geoPostal/ZIP● ready
Enter a postal/ZIP code and select a country to validate against that country official format. Supports US ZIP, UK postcodes, and more.
Reference
- geoCountry Codes● ready
Search by country name, 2-letter code (US), 3-letter code (USA), or numeric code (840) to get all other representations plus flag emoji.

Search NANP area codes (US, Canada, Caribbean) by number, city, state, or timezone. See overlay codes and geographic coverage.
Grids & Encodings

- geoMGRS● ready
Encode coordinates to MGRS grid references (e.g. 31U DQ 48251 11932) and decode MGRS back to lat/lon at 1 m to 10 km precision.
- geoPlus Code● ready
Convert between coordinates and Plus Codes — short, unambiguous location strings like 849VCWC8+R9 that work offline.
- geoAntipodes● ready
Enter a location and see the exact opposite point on the globe, the half-circumference distance, and the time-zone offset.

Frequently asked questions
How accurate is the distance calculator?
It uses the Haversine formula for great-circle distance on a sphere, accurate to within ~0.5% for most distances. For survey-grade precision, use a specialized GIS tool.
Does the IBAN validator check if the account exists?
No — it validates the IBAN format and checksum. It cannot verify whether the bank account is active or belongs to a real person.
How precise is a geohash?
Each character adds about 2.5 bits of precision: 6 characters cover roughly 1.2 km × 0.6 km, 10 characters about 3.7 m × 1.9 m, and 12 characters about 3.7 cm. Longer hashes pinpoint smaller cells.
What is MGRS?
The Military Grid Reference System builds on UTM: a zone number, a latitude-band letter, two 100 km square letters, then easting/northing digits. Ten digits resolve to about 1 metre; fewer digits give coarser 10 km to 100 m precision.
