"I mulled over this: which European country's phone calling code requires the longest search into π?
 E.g. Switzerland +41, 3 digits #math #pi"

A couple of folks asked about very small "countries" or territories that
had seemingly long calling codes but which are actually subsumed under
e.g. North American Numbering Plan (+1) which isn't in Europe anyway,
Vatican City (+379 & +39), Curaçao (+599-9) under Netherlands Caribbean,
etc.
