I have the .xml data with all of the latitude and longitude points from the nodes for California, but I need corresponding zip codes as well. Anyone able to point me in the direction of a simple way to get these through OSM? Thanks. asked 12 Jun '14, 19:22  ah2oman |

Can you provide a rough estimate on the number of nodes? If we're talking about, say 1000 nodes, I wouldn't have an issue recommending Reverse Geocoding provided by Nominatim. If that's more like a million, I'd be more than reluctant to recommend that though, unless you set up your own infrastructure for that purpose.
Unfortunately its going to be expanded to the US, so we're talking millions...thank you though for your response!
Then the only option is to install a local Nominatim instance and do the geocoding yourself. OSM doesn't have such a list but it can be generated using OSM data.
Maybe you can tell us your ultimate goal and we can try to find a better solution?
