NI number
Extracted from the Wikipedia article National Insurance number.
History
These sections dealt not only with the recording of NI contributions but with requests for information about qualifying contributions necessary to pay sickness, unemployment, widows, and other benefits and also with any correspondence arising from those NI accounts and NI cards. Within each of the sections, NI numbers were allocated among 16 splits, with one clerk administering each split. To trace unknown NI numbers, a general index contained millions of small RF2 index slips, filed in order of surname and listing the name(s), date of birth, and NI number for every person within the National Insurance scheme.
