National Insurance Numbers

[Inez10]

Does anyone know whether the numbers and letters making up the N.I. No. contain any information.  Can anyone tell your age from your National Insurance No.?

Your NINO is in the format  AB 123456 C

The two letter prefix can usually establish the date of issue of the NINO and the six digits are allocated sequentially.

Since most people are assigned their NINO as children as part of the Child Benefit payment system there is often a direct correlation between your prefix and your birthdate.

My sister's number and mine are exactly the same except the last digit of mine is A and hers is B.  They were issued over 6 years apart so i dont see how any of it could refer to date of issue

Siblings with consecutive numbers is explained in the first link above.

it is possible to kind of tell ages from ninos. ninos allocated in the 70's generally start with an N. 1970 is NW. in the 1990s they started generally with a J. its a bit of a rough and ready reckoner i know ,but sorry. i work with them every day. people who are not born as british citizens usually have them starting with a SE, SC or PW or PC (pre 2000). if you have been to a jobcentre and have been given one by them starting with a TN, this is a temporary number and only works in jobcentre related situations and not for tax purposes.

so someone could tell what age I am but not my sister?

 

Therefore you can only tell someones age so long as they are the oldest sibling?
