I am mapping in Iran right now and was wondering if there is any consensus about mapping addresses.
As far as I understand the system of addressing here every address is a post code that is unique in the whole country, consisting of 10 digits, the first five being the area code.
Is there any consensus about how to translate this to OSM tags? Split it to addr:postcode and addr:housenumber or put all 10 digits inside addr:housenumber?
And should I translate the number to Arabic numbers or leave it in Persian numbers?
And for the addr:street I assume we should just use the closest street name to the entrance?
Thanks for your help!
