"The ministry of Health said to-day that the former National Registration numbers will now be known as National Health service numbers and arrangements will be made to provide numbers for children and others who have no identity cards. Anyone using the service will be asked, as now, for his number when applying to be put on a doctor’s list or for dental or ophthalmic treatment. “Difficulty may be found,” the Minister’s statement says, “in getting this treatment if the number cannot be given.”
