Isle of Man

The Geoplan product also contains the Isle of Man Sectors IM1 0, IM2 0, IM3 0 and IM8 0, but do not actually

exist as real codes. This is because, although the extents of the Districts IM1, IM2, IM3 and IM8 are known, the

boundaries of the Sectors within them cannot be determined. No maps exist at the Isle of Man Post Office which show these Sectors, so the non-existent Sectors listed above were created by Geoplan to take their place.
