Zones 3/4 – Europe
Originally larger countries, such as the United Kingdom or France, were assigned two-digit codes (to compensate for their usually longer domestic numbers) and small countries, such as Iceland, were assigned three-digit codes; however, since the 1980s, all new assignments have been three-digit regardless of countries’ populations.
