is-national-insurance-number

This module provides a function to validate UK National Insurance numbers.

It validates strings strictly (must be upper case, contain no spaces, dashes etc).

I recommend santising your input before validation.

Installing

  npm install is-national-insurance-number --save

Example usage

const isNino = require('is-national-insurance-number');

isNino('AA111111A'); // true
isNino('thrasdfag'); // false

Using provided sanitiser:

const sanitiseNino = require('is-national-insurance-number/sanitise-nino');

sanitiseNino('aa 11 22 33 a'); // AA112233A
sanitiseNino('AA-11-22-33-A'); // AA112233A
sanitiseNino('aa112233A! 😺'); // AA112233A
