The BSN, PGN and OWN in the Netherlands can be validated with a 11 proef (elf proef). In this post I show you the JavaScript and TypeScript code.
In the Netherlands, we have a few identification numbers from the government. In this example, you can create a function to validate both of them based on the specification.
- BSN = Burgerservice nummer
- PGN = Burgerservice nummer in schools where the student doesn't have a BSN. The PGN is also called OWN.
How to use the code?
Define the function in your code and call it like this:
TypeScript example
// PGN/OWN
elfProefValidation('114435231', ElfproefType.own); // returns true;
elfProefValidation('34564366349', ElfproefType.own); // returns false;
// BSN
elfProefValidation('232262536', ElfproefType.bsn); // returns true;
elfProefValidation('247594057', ElfproefType.bsn); // returns false;
JavaScript example
// PGN/OWN
elfProefValidation('114435231', 'own'); // returns true;
elfProefValidation('34564366349', 'own')); // returns false;
// BSN
elfProefValidation('232262536', 'bsn')); // returns true;
elfProefValidation('247594057', 'bsn')); // returns false;
Working version
I created a working version on RunKit . Make sure you select Node version 17.
