bsn-js can be used to generate a test BSN (burger service nummer) or validate an existing BSN

works for JavaScript and TypeScript (type definitions included)

npm install bsn-js

or using yarn

yarn add bsn-js

import { isValidBSN } from 'bsn-js'

or

const { isValidBSN } = require('bsn-js')

pass the BSN (string) to the function and it will return true or false

example: const validBSN = isValidBSN('12312312') # false

import { generateBSN } from 'bsn-js'

or

const { generateBSN } = require('bsn-js)

test BSNs will consist of 9 characters

the Dutch authority has reserved BSNs starting with 0000 and 99999 for testing

the generetated BSN will start with 99999 by default

const bsn = generateBSN() # 999999400

when the function generateBSN is given true as argument, it will return a BSN starting with 0000

const bsn = generateBSN(true) # 000078840
