[1] La Poste Monaco operates seven post offices at various locations within principality; one in each of the wards of La Condamine, Fontvieille, Les Moneghetti, Monaco-Ville and three including the company's headquarters in Monte Carlo.

The post boxes also have a notice to mention the fact only Monegasque stamps are valid when using them, despite the rates being the same as in France.

By Decree of the National Convention on 27 October 1793, the Principality of Monaco was integrated into the territory of France until the passing of the Treaty of Paris on 30 May 1814.

The second interruption occurred just shortly after as a result of the Second Treaty of Paris (20 November 1815), which made Monaco a protectorate of the Kingdom of Sardinia.

This led to the Monegasque postal system becoming Sardinian from the signing of the Treaty of Stupinigi (taking effect on 1 January 1818) until the signing of the Treaty of Turin on 24 March 1860, again making Monaco a principality of France, and restoring the postal relationship.
