-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
Yes the Eircode system has flaws and will be closed. But that's the system we have to deal with. The UK Postcode system was closed for years as well. Alas "postcode" in Ireland will mean "Eircode". When Eircode is launched, we can start adding it to OSM in the addr:postcode tags. Maybe we'll do some sort of "free the postcode" for eircode. As for integrating with OSM, since openpostcode is an algorithm based on lat/lons, I don't think there is any way to "integrate" them (or is there?). OSM provides the lat/lons, do whatever with them. Please don't add openpostcode codes to OSM as "addr:postcode", that's inaccurate until people start using openpostcode. The openpostcode map uses Google maps though :P *Designing* a postcode is hard. openpostcode has flaws as well. Sometimes 2 houses of a semi-d will have radically different codes, meaning you can't use "ranges" at all (e.g. KFLRL2LN and JKQXQ6QF ). A take away nearby cannot say "We deliver to postcodes starting with KF".
