What is it?

Angular-js wrapper for jsvat

jsvat is a small library to check validity of European (and few non-eu) VAT number. ( learn more about VAT) jsvat use 2-step check (see below) and didn't make any request for external resources.

Each country has own regexp for VAT number and different math-logic of number calculating.

For more details check jsvat repo.

What angular-jsvat do

  1. Provide JsVatFactory facatory (just an angularjs wrapper for jsvat)

    Just check is VAT number valid or not and which country this VAT is: JsVatFactory.checkVAT('BG131134023'); // {isValid: true, country: 'bulgaria', value: 'BG131134023'}
    JsVatFactory.checkVAT('BG0433170001'); //{isValid: false, country: null, value: 'BG0433170001'}
    JsVatFactory.checkVAT('atu5-150-7409'); //{isValid: true, country: 'austria', value: 'ATU51507409'}
    JsVatFactory.checkVAT('aTU 5 804 4146'); //{isValid: true, country: 'austria', value: 'ATU58044146'}

  2. You can specify list of allowed countries

    JsVatFactory.config = ['austria', 'belgium']; //All countries except 'austria' and 'belgium' would return false
    JsVatFactory.checkVAT('BG131134023'); //valid VAT, but result would be 'false'


  1. Bower

    bower i angular-jsvat --save

  2. NPM (node.js)

    npm i angular-jsvat --save

  3. Directly download one of the latest releases:

  4. After that, just include angular-jsvat as a dependency

    angular.module('app', ['angular-jsvat'])

    (no dependencies required, angular-jsvat is standalone app)

How does jsvat check the validity?

It use jsvat) core functionality:

There is 2-step check:

  1. Compare with list of Regexps;

    For example regexp for austria is /^(AT)U(\d{8})$/.

    Looks like ATU99999999 is valid (it's successfied the regexp), but actually it's should be invalid.

  2. Some magic mathematical counting;

    Here we make some mathematical calculation (different for each country). After that we may be sure that ATU99999999and for example ATV66889218 isn't valid, but ATU12011204 is valid.
