I found the formula!
My daughter, who is 16, has been completing and submitting several job applications for fairly easy, first time job type jobs. After not hearing back from the majority of them, we both couldn’t wonder if not supplying a National Insurance Number could be the problem. In place of the NI#, she would simply write that a temporary number would be issued by employer, etc., and explain why.
WELL! I phoned back our local Job Centre Plus here in Taunton and spoke to Craig. I explained that I was informed of the process for getting the NI#, but in the meantime, could they issue a temporary. He did and explained what the temporary formula is!
TN (temporary number) followed by the day/month/year of birth (two digits) followed by an A:
TN110266A (TN 11th of February 1966 A)! Easy Peasy!
