I use this regex for Address:

   regex = new Regex(@"(?<strElement>(ADR)) (;(?<strAttr>[^\n\r]*))? (:(?<strPo>([^;]*)))  (;(?<strBlock>([^;]*)))  (;(?<strStreet>([^;]*)))  (;(?<strCity>([^;]*))) (;(?<strRegion>([^;]*))) (;(?<strPostcode>([^;]*)))(;(?<strNation>[^\n\r]*))", options);

You could try to find an existing library instead of reinventing the wheel. This for instance.

What options do you use?

If you don't use IgnorePatternWhitespace, then the spaces in your expression are a problem.

Another problem is, you check for a ; before "VOICE", but in your string there is a ,

Do you really need all those * quantifiers? If you want to make something optional, it is better to use the ? quantifier, it matches only 0 or 1 times.
