History
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.

Landline
Area code 0240 is presented as a geographic fixed-line identifier. Consult Autorité de régulation des communications électroniques, des postes et de la distribution de la presse (Arcep) for current allocation or licensing information.
