UTM Zone Map: Find Your UTM Zone
Click anywhere on the map to find the UTM zone number, band letter, EPSG code, and central meridian for that location. The map highlights all 60 UTM zones.
How UTM Zones Work
The UTM system divides the Earth into 60 zones, each 6 degrees of longitude wide. Zone 1 starts at 180 W and zones count eastward. Each zone uses a Transverse Mercator projection centered on its central meridian, which keeps distortion low within the zone.
| Zone | Longitude Range | Central Meridian | Example Location |
|---|---|---|---|
| 10 | 126 W to 120 W | 123 W | San Francisco, USA |
| 17 | 84 W to 78 W | 81 W | Miami, USA |
| 18 | 78 W to 72 W | 75 W | New York, USA |
| 30 | 6 W to 0 | 3 W | London, UK |
| 32 | 6 E to 12 E | 9 E | Berlin, Germany |
| 54 | 138 E to 144 E | 141 E | Tokyo, Japan |
| 56 | 150 E to 156 E | 153 E | Sydney, Australia |
UTM Band Letters
The latitude band letter (C through X, skipping I and O) identifies the 8-degree latitude band. For example, zone "18T" means UTM zone 18 in the latitude band between 32 N and 40 N.
Common mistake: Do not confuse UTM band letters with MGRS grid square letters. UTM bands are 8 degrees tall; MGRS grid squares are 100km squares within a UTM zone.
