Coordinate systems in Yemen: quick reference
Yemen's modern national datum is Yemen NGN96 (EPSG:4163), the frame adopted for new geodetic and survey work, used in practice with UTM zone 38N (EPSG:2089), which covers the centre of the country and its capital Sanaa. NGN96 is a modern datum close to WGS84, making it the most accurate choice for GNSS observation.
Yemen carries a dual legacy, though: before the 1990 unification, the People's Democratic Republic of Yemen in the south used the South Yemen datum (EPSG:4164) with a Soviet-style Gauss-Krüger belt, zone 8 (EPSG:2395), while the earliest Aden work goes back to the Aden 1925 datum (EPSG:6881). This mix means an old southern sheet may sit on a completely different system from a northern one.
The converter below opens on a Sanaa sample point and lists the Yemeni systems first. Enter your coordinates to get the value in every system that covers your location — from modern NGN96 to the heritage South Yemen and Aden grids — each with an explicit accuracy badge.
| EPSG | System | Accuracy |
