The Isle of Man Government owns the Isle of Man Post Office. Postcode searches require a registered email address (free) and rate limited to 10 searches per day. The government IT department sells the postcode/geolocation dataset to a very small customer base of couriers, dairy co-operative doorstep milk delivery service, Tesco, etc. An IT services company ( also resell geolocation datasets and data cleansing services.

Sep 2015: not all data available online or in one place but specific meta data available on request from public counters

Sep 2015: clarified that the Isle of Man Post Office supplies postcodes to UK Royal Mail PAF under a contract but it is unclear if the contract is exclusive or non-exclusive and a request to establish legal certainty some time ago has still not had a response (unsurprisingly if non-exclusive lol)

Sep 2015: coordinates are in ESRI GIS system (Cabinet Office) and UNIFORM gazetteer (Department of Infrastructure) as northings/eastings but standard algorithms to convert to lat/long kn Google Maps, etc.
