[dvdvol] Question regarding barrage of Chilean Requests

If you happen to drop by the requests list, we have had a recent influx from Chile. It appears that many of them have very short addresses. I have no idea if these addresses would work. I would expect to see the name of a city perhaps. Am I expecting too much? I don't want to waste a bunch of time, supplies, and money, but I don't want to disappoint a big group of interested people. I have a similar situation for a Colombian address as well. Both Chile and Colombia have postal web sites, but they are in Spanish and my ability to operate in that language is quite limited. Please let me know what you think. Thank you.
