What is the cost of a letter stamp in Monaco?

As of my last update in September 2021 the price for a domestic first-class letter stamp (Zone A) in Monaco was €1.15. This applies to standard-sized letters weighing up to 20 grams and sent within the country.

However, please note that this information may be outdated and stamp prices are subject to change. For the most up-to-date postage rates, it's best to consult the official website of Monaco Post or contact your local post office.
