Metropolitan France’s ten-digit national numbering plan became operational on 18 October 1996. It organised fixed numbers into five broad prefix families: 01 for Île-de-France, 02 for the north-west, 03 for the north-east, 04 for the south-east and 05 for the south-west. Arcep later relaxed these geographic rules in stages, ending location-based assignment restrictions for 01–05 numbers on 1 January 2023.
Since 1 January 2023, 04 does not prove a current south-eastern location.
