what is this?

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

It works for JavaScript and TypeScript (type definitions included).

installation

npm install bsn-js

usage

validate existing BSN

import { isValidBSN } from 'bsn-js'

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

Example: const validBSN = isValidBSN('12312312') // false

generate BSN for testing

import { generateBSN } from 'bsn-js'

The test BSNs will consist of 9 characters. The Dutch authority has reserved BSNs starting with 0000 and 99999 for testing.

The generated 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
