Country Standard Numbers


JavaScript (TypeScript) package to validate most all national numbers, with a focus on VAT, Person and Tax identifiers.

Quick start

import { stdnum } from 'stdnum';

console.log(; // 'Brazilian National Identifier',
console.log(stdnum.BR.cpf.localName); // 'Cadastro de Pessoas Físicas',
console.log(stdnum.BR.cpf.abbreviation); // 'CPF',

const {
    isValid, // is false
    error, // InvalidLength: The number has an invalid length...
} = stdnum.BR.cpf.validate('xyzzy');

const {
    isValid, // true
    compact, // '39053344705'
    isIndividual, // true
    isEntity, // false
} = stdnum.BR.cpf.validate("390.533.447-05");

All country validators are in the "namespace" of the ISO country code.

Supported Countries and Numbers

How you can help! This library currently support about half the countries in the world. It would be great if we can get to 100%. Submit an issue with any reference documentation and I'll do my best to integrate it, bonus points if you can get detailed descriptions of checksums or other validation criteria.
