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.
Define the function in your code and call it like this:
// 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;
// PGN/OWN
elfProefValidation('114435231', 'own'); // returns true;
elfProefValidation('34564366349', 'own')); // returns false;
// BSN
elfProefValidation('232262536', 'bsn')); // returns true;
elfProefValidation('247594057', 'bsn')); // returns false;
