If you have lost it

  • Report the loss on service-public.fr (loss) or at the police/gendarmerie (theft), then make a pre-application on ants.gouv.fr and book an appointment at the town hall.
  • The number of the old card is on the declaration receipt if you registered it, and on some past procedures (tickets, contracts) where you entered it.
