Use

VIES

As a static method:

EUVatCheckResponse resp = EUVatChecker.doCheck("IT", "00950501007");
Assert.assertEquals(true, resp.isValid());
Assert.assertEquals("BANCA D'ITALIA", resp.getName());
Assert.assertEquals("VIA NAZIONALE 91 \n00184 ROMA RM\n", resp.getAddress());

You can create an instance if you prefer:

EUVatChecker euVatChecker = new EUVatChecker();
EUVatCheckResponse resp = euVatChecker.check("IT", "00950501007");
Assert.assertEquals(true, resp.isValid());
Assert.assertEquals("BANCA D'ITALIA", resp.getName());
Assert.assertEquals("VIA NAZIONALE 91 \n00184 ROMA RM\n", resp.getAddress());

For error handling, see the tests, you may distinguish "invalid" and "error" which can have a Fault object:

You can use your own data fetcher if customization is needed, see:

TIN

As a static method:

EUTinCheckResponse resp = EUTinChecker.doCheck("BE", "00012511119");
Assert.assertEquals(true, resp.isValidStructure());
Assert.assertEquals(true, resp.isValidSyntax());

Like the VIES counterpart, you can see the tests for all the possibile outputs:
