This import regards the postal codes from Romania by matching the type of street, the name of the street and the street number on OSM with the corresponding fields from the Post's database. Only perfect matches are modified (e.g. if the type of street is different, no change is made).
This import has been discussed extensively on the talk-ro mailing list in November 2013
Postal codes will be added periodically, as more addresses are added in OSM.
You can contact the operator for any changes that should not be made.
