Package Exports
- valid-nino
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (valid-nino) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme

Validate a UK National Insurance number. Unit tested with alsatian.
Installation
npm install valid-ninoUsage
import validNino from "valid-nino";
validNino("AB123456C"); // true
validNino("TN50X"); // falseLogic
The prefix can be any two letters, except that the first letter cannot be D, F, I, Q, U or V; and the second letter cannot be D, F, I, O, Q, U or V. In addition, there are seven two-letter combinations that are specifically disallowed, these being BG, GB, KN, NK, NT, TN and ZZ.
The second part of the NI number is a straightforward string of exactly six digits, that is, a number between 000000 and 999999. It never contains leading spaces or other extraneous symbols.
The suffix is either a single letter, in the range A to D, or a space. Although it's always present (if it's a space, the NI number is not trimmed), it is not required for uniqueness. So, if AB123456C is a valid number, then no other number will begin with AB123456.
