Although Moe’s Tavern has featured many times in the chapters, until recently it was known that the telephone number of the tavern was exposed in Episode 17, Season 7, when Mr. Burns tries to call his assistant Smithers after Homer takes his place at the plant.

This is how FayerWayer describes it, who ensures that when Burns calls his assistant and without knowing the number communicates directly with the traditional tavern of ‘The Simpson’.
This same statement is made by Ámbito, from Argentina, which emphasizes that one of the curiosities is that this number has one digit more than those used in that North American country, so it may be a new trick from the writers to keep the place hidden of the map that Springfield is on.
Even, adds this last medium, in the United States there are about 35 localities that bear the name of the city of ‘The Simpsons’.
