What steps will reproduce the problem?

an Irish vat number is accepted by vies and not by the library. for example the following vat number : IE1113202EH is somehow validated by VIES even if it doesn't match the Irish vat number format described on wikipedia

What is the expected output? What do you see instead?

>>> vatnumber.check_vies('IE1113202EH') True >>> vatnumber.check_vat('IE1113202EH') False

Expected to see True

What version of the product are you using? On what operating system?

version 1.0

Please provide any additional information below.

I couldn't find any information on any change on the Irish vat number format which is supposed to be 8 digits length (not 9)

See http://www.vatlive.com/european-news/ireland-vat-number-format-from-january-2013/

irish validation is now done using python-stdnum. You should report this issue on their bugtracker: https://github.com/arthurdejong/python-stdnum
