In practice, the number E33 does not appear on any road signs. Instead, its entire stretch is signposted as E31, creating a duplication with the European route E31, E31 in Germany and the Netherlands. This goes back to the numbering set forth in the original European Agreement on Main International Traffic Arteries (AGR) of 1975, in which Parma - La Spezia was numbered E31 and Rotterdam - Ludwigshafen was numbered E33. These numbers were swapped upon the AGR's entry into force in 1985, apparently resulting from the fact that the Parma - La Spezia route is entirely situated east of the Rotterdam - Ludwigshafen route so that the former should under AGR principles have a number above the former. This numbering change, however, never made it onto Italian signs.
