UTM zone
Enter a latitude and longitude to find the zone.
Understanding UTM zones
The Universal Transverse Mercator (UTM) coordinate system divides the Earth into 60 zones, each 6° of longitude wide. UTM identifies locations using easting and northing coordinates in metres, which makes it convenient for surveying, mapping and GIS.
Zone numbering
- Zones 1–60: starting at 180°W, zones increase eastward
- N/S suffix: northern or southern hemisphere
- Zone width: each zone spans 6° of longitude
- Latitude limits: UTM is valid between 80°S and 84°N
Why use UTM?
- Metric units: coordinates are in metres, so distances are easy
- Low distortion: within a zone, distortion stays under about 0.1%
- Universal: a standard system used worldwide
- Compatible: works with every GIS package and GPS device
Special cases
A few zones have irregular boundaries to keep a country in one piece:
- Zone 32: widened to cover Norway (56°N to 64°N)
- Svalbard: uses zones 31, 33, 35 and 37

Looking for a specific place? UTM zone by city lists the zone, EPSG code and central meridian for 75 cities, with how far each sits from its zone boundary — the number that decides whether one zone actually covers your site. London, for instance, is 9 km from the zone 31 edge.
Frequently Asked Questions About UTM Zones
UTM zones are 6° wide longitude bands numbered 1-60 from west to east. The simplest method: take your longitude, add 180, divide by 6, and round up. Or use our interactive map to click your location for instant zone identification with EPSG code.
EPSG codes uniquely identify coordinate reference systems (CRS) used in GIS software. Using the wrong EPSG causes data misalignment - your map layers won't overlay correctly. For UTM Zone 43N (WGS84 datum), use EPSG:32643. Northern hemisphere zones use 326XX, southern use 327XX.
WGS84 is a geographic coordinate system using latitude/longitude in degrees - it's what GPS uses. UTM is a projected coordinate system using meters on a flat grid. UTM is better for local measurements and surveying because distances and areas are in meters, while WGS84 is better for global applications.
Misaligned layers usually mean CRS mismatch. Check that all layers use the same EPSG code. Common mistake: mixing WGS84 (EPSG:4326) with Web Mercator (EPSG:3857) or UTM zones. Use our tool to identify the correct EPSG code for your project area.
Use the UTM zone where your project is located. If your project spans two zones, choose the zone containing most of the area, or use a local projected CRS. For global projects, consider Web Mercator (EPSG:3857) but be aware of area distortion at high latitudes.
