Sitting discussing this at the moment. DD is 16, online it says that before your 16th birthday you should receive a National Insurance Card through the post but we've received nothing. This doesn't surprise me as we have moved house 3 times since she was born so therefore school as well. She is also at an independent school so not registered for state education either.
How do they find out where she is? Do we have to contact someone about it? Not sure what we need to do!
