export default regexps;

Other option for phone number: /^((\+|00(\s|\s?\-\s?)?)31(\s|\s?\-\s?)?(\(0\)[\-\s]?)?|0)[1-9]((\s|\s?\-\s?)?[0-9])((\s|\s?-\s?)?[0-9])((\s|\s?-\s?)?[0-9])\s?[0-9]\s?[0-9]\s?[0-9]\s?[0-9]\s?[0-9]$/,

This matches:

Some valid examples as how Dutch people would write down their phonenumber:
0101234567
010-1234567
010 - 123 45 67
010 1234 567
06-12345678
06 123 456 78
0111-123456
0111 123456

International notation:
+31101234567
0031101234567
+31(0) 10123 4567

Dear @RobSchilderr , hope the Regex-ies for Nederland didn't change since then. Anyway, thanks a lot !

BTW, I think for IBAN, the regex might be : /^NL[0-9]{2}[A-z0-9]{4}[0-9]{10}$/'
