What is the postal code of the region in France called Ile-de -France Paris?

Answer 1

There is a different postal code for each town, and in big town like Paris there are several postal codes. One way of finding it is to run a quick search on Google.fr, (enter the place name + "code postal"). This should return the postcode (a five-digit number). Another way is to enter the name and town of the person you are looking for in an online phone directory, like the "pages jaunes" (follow link for that one). The person has to be listed in the phone directory. The answer will include the full postal address including the zip code.
