Geo & Location Tools
Convert between DMS and decimal coordinates, calculate distances, validate IBANs and phone numbers, look up country codes, timezones by location, UTM conversion, area codes, and bounding boxes — all client-side.
Most popular
- geoCoord Conv.● ready
Enter coordinates in DMS (degrees, minutes, seconds), decimal degrees, or degrees-minutes and convert between all formats instantly.
- geoDistance● ready
Enter two sets of latitude/longitude coordinates to compute distance in kilometers, miles, and nautical miles with initial compass bearing.
- geoPhone Valid.● ready
Enter a phone number to validate its format, see the country, national format, E.164 international format, and detect the number type.
- geoIBAN● ready
Enter an IBAN to validate its format, check the MOD-97 checksum, identify the country and bank, and format it with proper spacing.
- 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.

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.
