The main function of the French Post Office (La Poste) is to convey letters (though La Poste also provides banking services, and you can open an account there). Letters for destinations within France usually arrive the next day, for EU countries 2-4 days and for USA up to 7 days. In many post offices, you will find automatic stamp machines, telephone booths and photocopiers.
The cost of sending a letter depends on its weight and destination. For EU destinations, it costs 0,54€ to send a letter weighing up to 20 grams. For countries outside the EU, there are different prices for each geographical region. A letter weighing more than 20 grams must be marked Lettre (all post offices have weighing scales and label dispensers).
An essential part of all addresses in France is the five-digit postcode that identifies the commune. The postcode immediately precedes the name of the town or village, on the last line of the address for all mail within France. The first 2 digits of the postcode indicate the number of the département; and the last 3 digits identify the commune (for example, 56470 is the postcode for the town of La Trinité-sur-Mer in département number 56, i.e. Le Morbihan). For large cities with arrondissements -districts- like Paris, the last 2 digits of the postcode indicate the arrondissement; for example: 75006 PARIS means “Paris, 6ème arrondissement”. Post offices are usually open from 8 am to 6pm Monday to Friday and from 8am to 12pm on Saturday. Exact hours may vary from office to office. In Paris, the post office on Rue du Louvre (2ème arrondissement) is open 24 hours daily.string(0) ""
