Starting in January 2026 or 2027, depending on the location, new subscriptions for copper telephone and internet lines will no longer be available in France. The T-socket, a standard electrical socket found in most homes, will no longer be used for new connections. The copper network, which has been in use since the 1970s, will be gradually phased out until the end of 2030. This transition will affect more than 23 million homes as fiber-optic connections replace copper lines. By early 2026, fiber coverage is expected to reach 94% of homes, using a set-top box instead of the traditional T-socket for internet access. The closure of copper lines occurs in two stages. First, the commercial closure stops all new subscriptions, regardless of the provider. This stage is scheduled for January 31, 2026, or 2027, depending on the commune. Following this, the technical closure stops existing copper services, which can only occur at least 12 months after the commercial closure. The regulator, Arcep, has stated that nearly three-quarters of communes will experience the commercial closure in 2026, with the rest following in the following months. Existing ADSL internet and fixed-line telephone subscriptions will remain active, but no new copper subscriptions will be allowed. The transition is being carried out in five phases, with the first one completed in March 2021 for 700 homes in Lévis-Saint-Nom. Lot 1, covering 162 communes and 209,000 homes, was closed by the end of January 2025. Lot 2, which includes 829 communes and nearly 1 million homes, will have its technical closure on January 27, 2026. Lot 3, covering 2,138 communes and about 2.5 million homes, will be closed on January 31, 2027. Lot 4, with 6,894 communes and 8.3 million homes, is scheduled for 2028, followed by Lot 5, covering 10,470 communes and 11.7 million homes, in 2029. The entire process is expected to be completed by the end of 2030. Fiber-optic connections will replace copper lines, and by early 2026, fiber will be available in nearly 94% of homes. Unlike copper, fiber does not require a T-socket; instead, it uses a set-top box for internet access. The T-socket will remain on the wall but will no longer be used for connecting to copper lines. Some services, such as remote monitoring and assistance, will also be affected. The exact closure dates may change, as nearly 8,000 communes have had their schedules postponed to avoid subscriber disconnection risks. Orange has announced the technical closure of 763 communes, or about 900,000 homes, on January 27, 2026, slightly less than initially planned. Before January 31, 2027, it is important to check the status of your home’s internet connection using the Arcep’s online tool, Ma connexion internet, which shows the available technologies and applicable closure dates. Orange also provides an interactive map and a closure trajectory file for reference. If you are moving homes after January 31, 2027, and the new home is still connected to copper, you will need to use fiber to set up a new internet connection. The transition from copper to fiber is a significant change for many households, requiring careful planning to ensure uninterrupted service.
