Coordinate systems in Iraq: quick reference
Iraq’s best-known national datum is Karbala 1979 — the basis of cadastral and municipal work — used either geographically (EPSG:4743), through the Iraq National Grid (EPSG:6646), or via UTM zones 37 to 39 (e.g. EPSG:3392 for Baghdad’s zone 38). Before it, the Nahrwan 1934 datum (EPSG:4744) with the Lambert conic “Iraq zone” projection (EPSG:3394) underpinned mapping across Iraq and the wider region.
More recently Iraq adopted the IGRS frame (EPSG:3889), tied to the global reference frames, for new GNSS work. An older ED50-based edition of the national grid (EPSG:3893) also circulates, carrying only ballpark accuracy of several metres — the tool surfaces an honest accuracy badge for every system.
Baghdad (44.4°E) falls in UTM zone 38. Enter your coordinates below — the converter opens on a Baghdad sample point and lists the Iraqi systems first.
| EPSG | System | Accuracy |
|---|---|---|
| 4743 | Karbala 1979 (projected-variant geographic)(geographic) | ±0.1 m |
| 6646 | Karbala 1979 / Iraq National Grid(projected grid) | ±0.1 m |
| 3392 | Karbala 1979 / UTM zone 38N(projected grid) | ±0.1 m |
| 3394 | Nahrwan 1934 / Iraq zone (LCC)(projected grid) | ±0.1 m |
| 4744 | Nahrwan 1934(geographic) | ±0.1 m |
| 3889 | IGRS(geographic) | ±0.1 m |
The tool covers 19 systems relevant to Iraq (national systems plus the WGS84 UTM zones) — the table above lists only the key ones.
FAQ
- Which coordinate system does Iraq use?
- Cadastral and municipal work sits on Karbala 1979 (geographic, the Iraq National Grid EPSG:6646, or UTM); older maps use Nahrwan 1934 with the Lambert “Iraq zone” projection; modern work observes on the IGRS frame tied to the global reference frames.
- What is the Karbala 1979 datum?
- A national geodetic datum established during the Polservice survey campaign of the 1970s; it became the basis of Iraq’s land registry and municipal mapping, used with the national grid and UTM zones 37 to 39.
- Which UTM zone is Baghdad in?
- Baghdad (about 44.4°E) sits in UTM zone 38N — EPSG:3392 on Karbala 1979, or EPSG:3891 on the modern IGRS frame.
- What is the difference between Nahrwan 1934 and Karbala 1979?
- Nahrwan 1934 is the older datum (origin station at Nahrwan near Baghdad), used with the Lambert conic projection; Karbala 1979 is the newer datum behind modern cadastre. Legacy sheets are often on Nahrwan and newer ones on Karbala — mixing them shifts points by tens of metres.
- How accurate is the WGS84 to Karbala 1979 conversion?
- The published EPSG shifts for Karbala 1979 are good to a few metres or better, while the ED50 edition of the national grid is only ballpark (around 9 m). Centimetre-grade work needs a local geodetic fit — a service we provide.
