National Insurance number cards
HMRC are to stop issuing plastic national insurance (NI) number cards.
With immediate effect, HMRC will no longer be sending replacement NI number cards. Instead they will simply, when requested, provide confirmation by letter of an individual’s NI number.
Children approaching their 16th birthday will continue to receive plastic cards notifying them of their NI number for the moment. This will also be the case for first time applicants for an NI number.
